    5:53 is in my opinion one of the most important notes of this test for anyone worried about heating up the air going into their engine. The fact that no matter the configuration your inter cooler is still doing its job is worth noting. While you don't see performance gains with the same tune all around I still have to wonder if the improved air flow helps increase your hp after a performance tune compared to stock. (just noticed the last comment on this video was 3 years ago...oh well)

    As the temperature graph you showed in the video proves, a cold air intake source does not provide "extra" power, it merely makes an engines' potential power production more consistent over time by keeping intake air temperature more consistent. This is actually less of an issue for drag racers than for road course or roundy-round runners for example.

    The stock intake comes with a snorkel which feeds into the bumper. That being said, these guys didn't keep all the variables constant for this experiment. A properly designed cold air intake feeds the pod filter into the bumper just like the stock intake snorkel.
    What their experiment shows is that short ram intakes with the conical filter in the engine bay feeds hotter air into the engine resulting in a power and efficiency loss vs. the stock filter.
    To deliver colder air into the engine with the intake there air two things to keep in mind, filter location and pipe material. Metal absorbs much more heat from the engine bay than plastic or rubber, so metal piping will heat up the air inside more than plastic/rubber or wrapped piping. Lots and lots of variables to consider, that's why good intakes cost so much money and they really just aren't worth it if you're not boosting the stock engine where restriction isn't an issue.

    • @smurphy505
      @smurphy505 Před 10 lety +2

      UPDATE: So I actually did purchase a DC Sports cold air intake ($152) for my Integra. While installing the cold air intake I learned that on my car there actually isn't a snorkel from the stock intake that pulls in outside air. Instead, the stock intake recycles air from the engine bay through an air box within the passenger side splashguard.
      What this means is my stock intake wasn't even drawing in outside air, but actually pulling in air through the engine bay, into this air box above the splashguard, and up to the filter. My cold air intake feeds the pod filter above the splashguard so it is truly drawing in cold outside air. I put an AEM Dryflow cover over the filter to prevent any chance of hydrolock.
      I haven't gotten the Integra on a DYNO before and after, but I have definitely noticed an increase in power. My idle speed is greater, the car pulls harder in the 5-7k rpm range, and I get more pull in the low rpms while in 4th gear. Also I got a lean code from the extra air being drawn into the engine, so I simply reset the ecu to adjust to the extra air being drawn in.
      Drawing in cold air does result in greater hp as their video has shown. You just have to decide is paying for a real cold air intake (not a short ram intake) is worth the money. For me, $152 for what I've gained was well worth it.

      If you buy a cheap intake it won't do anithing, im no implying, expensive is allway the best option, becouse it cost more, but becouse is been bouild with a better quality, and this translate to efficient air intake, is not the same to put a 50, dolar intake for your engine, and expect the same results, as to buy an intake for 150$ made by Japane, or one made on USA, the performance will be different due to the quality, of the part you are buying, in this case a cold performance intake.
      Fartheremore we don't know the make or price of this intake, they might look similar as an expensive one, but surely won't operate the same, so unless I know where and how much this intake cost, I won't take this video sirusly and you shouldn't either.

  • @camenisawok8499

    1) You need to drive the car around for few days for the ECU to learn the difference and adjust itself accordingly.
    2) A drop in performance air filter will give u noticeable throttle response. Your foot will feel the difference throughout the rpm range.
    3) Stay away from oil filter and stainless steel filters. They mess with your air flow sensor, your idle will become unstable.
    4) The sound from your engine bay will put a smile on your face.

    • @assininecomment4934
      @assininecomment4934 Před 4 lety

      Okay, but what does "give u noticeable throttle response", actually mean? Is that a faster increase in volume of airflow, after moment of throttle position change? What does "mess with your air flow sensor", actually mean? Can you direct us to any measurements or other evidence of throttle response, or airflow sensor function errors, following fitment of an oiled element air filter, or "stainless steel filter"? If we're taking about specific components and specific modifications, something more specific that "your foot" makes sense.

      @cheetahgaming3642 Před 4 lety +1

      @@assininecomment4934 ok first up about the sensors... on Oil-Based filters sometimes under heat the oil can drip onto the intake sensors (MAF Sensor, Map, depending on what your car has) there for altering the tune of the engine tricking it into running potentially leaner, therefore causing rough idle, power loss, and pinging. It also makes the emissions worse... Now about the throttle response, when you press the throttle in a stock airbox their may be a slight delay similar to turbo lag but much more minor, this can be due to a bad filter yada yada yada but when you switch to a pod filter, you open up the area at which air can enter the intake, from a small 25mm hole in the side to ALL SIDES of the filter. This can mean when you press the throttle you get INSTANT torque and even a potential power gain (a lot of factors go into that though) in my car you can definitely feel a difference in throttle responsivness, but after driving it on track it got a very stalley idle and pinged at very low rpms. it is old and its the first time its been driving hard in probably 2 years, so im guessing a lot of gunk has gotten onto the sensors (like i previously said) and caused these issues... one thing i will not agree on is the "ecu drive it for a few days" thing, thats utter bullshit. after 1 or 2 pulls and hell just starting it will make the ecu do 99% of the changes, and most cars with pod filters are tuned to be fuel efficient anyway so a ecu tune or reflash WILL see gains on these engines... ralliart ecu reflashes in my car see up to 10% or 6kw gains which as they said IS a noticible gain.......................... overall this has taken me 20 minutes of my life to type, why did i do this... you BETTER apreciate this ahahhahah

      @@cheetahgaming3642 - Thanks, mate - do appreciate your time and thought. Yes, I am familiar with those grubby sensor woes, though not personally. I guess it could be minimised by moving the air filter to a position where it won't absorb much engine bay heat - otherwise the whole (potential) benefit of any 'cold air' system is utterly negated. Even prior to any tuning changes, and even if *peak* power output isn't necessarily increased by some (millions of) free-flow / 'sport' air filter systems - maybe the quicker response, and increase in power and/or torque outputs *earlier* in the rev range, are there to be enjoyed.

    The only reason to fit a 'cold air intake' filter to a turbo charger, in my opinion, is essentially to act as a FILTER (dust, gravel, mud etc from damaging the housing) rather than serve as a cold air intake. It is not a practical addition to a turbo'd induction system as air is compressed (heated, eventually) and flows to the intercooler for initial cooling. So, what they were trying to prove/bust was done in a bad setting. Would have been a more effective experiment if applied to an N/A vehicle, outdoors and actually driving the car.

  • @tallnrough68

    You guys forgot to tune the car as well. Just adding a new intake won't yield any benefits until you have the proper fuel injectors, ecu mapping for airflow to gas ratio and placement of the man sensor is crucial as well. You'll probably gain about 10hp on a 200hp car. It's not much but where the torque band slouched, you'll see the gains there. It's not just slap on and you're ready to go. The computer in the car is mapped for stock hardware.

      I completely agree with that, but most people believe you just change the filter and make gains. I think that's the myth that's being busted here. Ultimately if you want to gain power by letting more/cooler air in, you need to deal with getting it out more efficiently too so an uprated intake is useless without a bit of exhaust work. Although your comment suggests you probably know that

      @norwester7018 Před 10 lety +2

      Yes and no... Yes, it would be a better test WITHOUT all the FI plumbing and in reality a Intercooler IS a CAI in effect if the goal is to lower induction air temps...
      But in reality, no, CAI's like they're testing do nothing to a car on a dyno and only a tiny TINY bit (if anything) on an average car moving at speed. I've done this on my MK1 2.0L 16v swapped GTi track car (won't do it on the rally cars cause they already breathe out of the cab or the side glass induction in-let depending on the stage/course)... I moved the Intake down to the bottom of the bumper and all it actually did was make the filter get dirtier faster. I was actually faster with the previous set-up by .13sec, but that could just be lap variance and my point is the CAI did NOTHING to an NA engine that is built to breathe and has a low restriction exhaust system. However on a cold misty day, I managed my best lap yet, by over .64sec and I could feel more power all around the rev-range. This is why Rally-cars run water injection on the intake, much like a cold misty day it cools the intake temp and increases the air-density more effectively then just moving the intake down low does. BOTH of those things combined could actually do quite a bit in the right conditions. That's the other thing, in wet rainy climates, running a CAI down near the ground only increases the chance of water induction (hydro-locking is no bueno) and in some cases on wet days when the air is already cool and damp it can be the "straw that broke..." in that it won;t allow the engine to get up to proper operating temp and if the car has a "fifth cold start injector" it'll mean the engine runs rough and way too fuel heavy killing power and fuel econ.
      Outside atmospheric temp and air-density make WAY more difference and the simple moving of the intake to down lower on the bumper/grill does little to change the charge temp. It's pretty interesting as I Daily Drive a 22RE 1st Gen 4Runner/Hilux Surf and on cold rainy days (here in Oregon, those happen all the time) it pulls harder and get's better mileage, and on hot summer days I get worse mileage and have less power... it's SLIGHT but it's noticeable to me. Putting a Snorkel on the truck did nothing to up the power in the warmer weather. It still runs stronger on cold rainy days.
      In this case, the CAI was already THERE from the factory and was just a small part of an engineered engine/drive-train designed to make power. On an average car it will do nothing but give you a louder induction "sucking" noise... which, funny enough, a LOT of people can psychologically convince themselves is "more power" and that they can "feel it".

    • @paulcutts1731
      @paulcutts1731 Před 10 lety

      Thanks for an epic answer! maybe a psychological difference is worth the few dollars. I watched a video recently featuring the guy who designed the F-type ad he said the air intakes on road cars are so optimized these days that any generic replacement wont e as good on any car made in the last 8 years or so. He recommended it only if you had massively increased he engine need for air with chips and turbo back exhausts bored out etc.. so that bears out exactly what you're saying.

    • @norwester7018
      @norwester7018 Před 10 lety +1

      ***** Cheers mate, in reality I just talk too much hahahaha... you've hit the nail on the head with OEM's too, cars today are SO much more volumetricaly/fuel efficient that really slapping on some $100 tube that moves the air-intake to a different place doesn't really do much and in some cases will actually DECREASE power. That's not to say that CAI's in general are stupid and useless (they're not and the GT-R has always had one from the factory), just that it's only ONE PART of a larger system. The old adage "an engine is an air pump" is still true today. I look at it like this: If you spend every day in the gym working on one single muscle, have you really made yourself "stronger" as a whole??? Modding engines is the same way. You have to look at baseline numbers, power curves, power delivery points and on and on and then do modifications to improve the engine where it needs it. And again, JUST like the vid you watched, these days, OEM's (car companies) are doing SO much to improve efficacy in the hunt for better fuel econ that they're making cars more powerful and harder to "improve" with simple little add-ons like these. It's nothing like "tuning" was even 10-15 years ago where engines weren't nearly as highly engineered for efficiency. Making more power and getting better mileage/lower fuel consumption out of an engine are often very similar processes. Certainly most, even extreme performance engines, can make "more" power, but most of the time you're either moving WHERE the power comes in around the rev-range, or your sacrificing reliability and drive-ability in the process of making that power (there are some exceptions, but that's a pretty good general rule of thumb). One of my old MKII Jettas made 265whp (!!!) on the dyno from a 16v 2.0L but it was TERRIBLE to drive on the road cause the cam I had to use was so "lope-y" and peaky and it made it's power so high up in the rev range that it just wasn't a good street car and really didn't do all that much better at the track. So yeah, I made more power, but at what cost??? Anyway...
      See, told you I talk too much... Best to ya mate,

    i think on turbo cars, doesn't matter if it's cold air intake or hot air intake, the air will be compressed by the turbo which will get hot anyways. So the intercooler is doing most of the cooling for the air before get into the manifold

    • @hypr1
      @hypr1 Před 9 měsíci

      I used to think this too but the intercooler doesn't cool all air to the same temperature. If intake air temps are higher, intercooler air temp will be higher as well, which means less dense, less oxygen. Even with a turbo superheating the intake air, if it's colder to start, it will be colder once it reaches your engine

    • @bigcazza5260
      @bigcazza5260 Před rokem

      probably none, the initial air is still hot and since you are compressing it all you will do is cool atmospheric pressure, better off putting a snorkel on for ram air intake

  • @qscvkg
    @qscvkg Před 8 lety +10

    honestly, when it comes to this stuff I just feel like it depends on the car, the R32 skyline already has a system to feed cooler air through the engine for max performance because of the fact that that is what the car was designed for, performance, no need to fix a stock performance air intake system with another performance air intake system you know? However there are some cars out there that have a very restrictive intake system, and it is on those specific cars that you might gain something, do I believe a cold air, or short ram intake can add 20%? hell no, however you might gain a horsepower or 2 with it. Not significant, however at least it is something.

      True to a degree. With modern cars control systems keep the air fuel mixture, etc. with much more precision. So with an old style carburetor changing the inlet temperature or restriction changed air mass flow and likely the mixture. Still even in a modern engine, colder, denser air should mean more mass flow and more power,

    • @97markviii
      @97markviii Před 9 lety +8

      The gains are real, but even less on turbocharged car. On a N/A car gains are going to be around 5%, no tune is necessary because the ecu sees air density and air temperature and adds timing and fuel accordingly. Why mcm used a turbo car was either to prove their point or were not thinking because a turbo runs off hot exhaust gases.

    • @justussmith3080
      @justussmith3080 Před 9 lety

      Yes it will set off the CEL, but if you reset the computer (i.e. Unhook the battery, turn the key in the ignition a few times to totally drain the power from the computer, and reconnect the battery) it goes off because resetting the computer forces it to adjust the fuel flow to the engine to correct the air/fuel ratio. And that is when you see gains. Just adding more air will make it run too lean and cut your power. If the computer adjusts to the extra air, it will add extra fuel to compensate, and with both more air AND more fuel, you can produce more power.

    • @ningen1980
      @ningen1980 Před 9 lety +2

      Justus Smith You're partly right about wiping the ECU by disconnecting the battery.
      Disconnecting the power supply forces the ECU to lose all fine tuned fuel maps that are saved in volatile memory (memory that needs constant power). Disconnecting the battery for a long period ends up sending the ECU into a failsafe mode that provides an air/fuel mixture of roughly 14.7:1.
      Once the ECU starts fine tuning the mixture, spark timing, valve timing and all the other aspects, It will push toward tuning itself to predetermined limits set by the manufacturer.
      Ultimately, the ECU will still throw a CEL and go into "limp mode" if it still detects more airflow than it can handle (I.E. an aftermarket intake). The only way to get rid of the CEL issue is either with a custom tune, or using the stock airbox.

    • @justussmith3080

  • @matreyia
    @matreyia Před 10 lety +10

    Guys, if you expect gains from intake with no ECU adjustments to compensate, it probably won't happen. There gains to be made otherwise the whole industry would be faking their dyno data. I'm sure they do it under their own ideal conditions. And these "cold" air intakes are not really effective because they are in the engine compartment.
    I'll see for myself next week when I install the Dinan Carbon Fiber Cold Air Intake (a true cold air completely insulated system that takes air from the lowest part of the car in the front fender) to mate with my Dinan S2 software upgrade. This intake is totally insulated and has mainly carbon fiber walls and it doesn't replace the stock intake but rather supplements/adds more air (40º cooler than stock air) to the stock intake.
    So far, adding a BMW M Performance exhaust with the software has made noticeable diffrence...the wheels skid more with the same driving style and intensity.
    We will see if the intake addition makes a noticeable increase in performance.

    • @jimfallowfield7028
      @jimfallowfield7028 Před 10 lety

      Keep hearing that you need to adjust the ECU for this to work. The ECU knows what the incoming air temperature and adjusts the fuel curve to compensate. The whole point of electronic fuel injection is that you don't need to tune the car for different environmental changes.
      When I hear that a CAI works best with a tune I think of that movie GO where the girl selling the fake ecstasy says you will feel it work better if you smoke a lot of pot.

    • @matreyia
      @matreyia Před 10 lety

      Well Jim, I'm not a mechanic or engineer. But I imagine that although companies want to make profit, they do have to have some data to back up their claims, however ideal conditions they use to come up with the numbers, they are still there. This video most likely doesn't show the intake accessory in the manner that the factory did their testing. Is that realistic? Of course not, you can't trust companies for their inflated numbers. But I'll take the path of personal experience, so if you will forgive me, I will see for myself if that $1200 I just spent really made a difference. I already spent 1300 on the BMW exhaust and it certainly made a noticeable difference with same style of driving so that is why I reserve judgement.
      Too many factors to consider so can't say universally that it is worthless or worthwhile...either way.

    • @cootercope
      @cootercope Před 10 lety

      matreyia if you want to see the best gains disconnect your battery to reset your fuel trims and let the fuel system relearn it with that air intake set up. then you will know you wasted money. the best way to gain the slight amount of hp is to just swap out your intake tube to one without any noise baffles.

    • @matreyia
      @matreyia Před 10 lety +1

      John Mann That can be done without disconnecting the battery on an e93.
      Should I even ask you if you know the Dinan CAI system for the e93 and how it works? From your words, it does not seem you know the system. There is no swapping out anything, there is no replacing the stock intake. Every is stock, the only difference is there is a supplemental forced induction system configured to add 40º cooler air to mix with the stock intake. Not only is there additional air, that air is also 40º cooler. And the Dinan software ECU upgrade is configured to take advantage of the extra cooler air. Right now, the Dinan software is not taking advantage of the intake as it was intended to do...so...
      I can come back here to report my impressions after next week when the intake system is installed. Or I can stay away if people don't want to hear it because they already know everything in every case. It could end up impressing me with noticeable gains like the M Performance exhaust I just installed, which immediately integrated to the Dinan software to increase output. Since I did not expect this gain, I would say that it is not imaginary or placebo...nor are my tires lying to me.

    • @drjim86
      @drjim86 Před 10 lety

    this test is misleading and confusing to most people. this car is designed for high performance already. if you replace the intake on a stock car that was designed to reduce noise and save gas, then you will probably see a difference when you remove the small restrictive plastic ribbed pipes. you will see even more of a difference if it is taking in fresh cold air than if it was taking it from the hot engine bay.

      Hey Dan, PSI and density aren't the same thing. The atmosphere is at 14.7 psi. And at 14.7 psi, cold air is more dense than hot air. That's why If you stick a balloon full of hot air in the fridge it shrinks. This principal doesn't change at higher psi. If you're pumping 20 psi of cold air, you're getting more air than if it was hot.

    • @VashStampede81
      @VashStampede81 Před 10 lety +3

      Which like Cody said would explain why you would also get different results at higher and lower elevations due to air density. I know my K&N worked for my SRT 4 . I could drive it in 5th gear going less than 25mph / 40kmph and still spool air into the turbo. Doing a launch I could smoke the tires all the way to 5th Pipe diameter, shape and length have a lot to do with how fast the air can be accelerated through the intake into the turbo, allowing a higher density of compacted air molecules, which allows the computer to adjust for more fuel, allowing more power (in a WOT situation this is maximized). Companies who do extensive testing, such as K&N tend to achieve more nominal results.

    they mythbust nothing
    CAI's don't do much or even hurt on stock sytems, since the ECU is configured for stock filter
    but they are a mod that make you able to gain much more power with a decent tune than with stock filter
    on mkIV forum (supra) there is a test with Blitz, Apexi, K&N, HKS and some other filters vs stock
    the test car was tuned and all filters gave around 14bhp gain, while the blitz(metal mesh) and hks(foam) were VERY poor at filtering and K&N filtered reasonably
    The apexi gave most bhp gain (although only 0,5) but was most definately the best filter. Probably even better than stock paper filter
    all I wanna say is: CAI on stock does only give sound
    CAI with mods can help
    when using pod or panel filter, use one which also filters well (injen/amsoil, apexi, aem dryflow for example)

    It might be like cooling a radiator. You need to have air forced into the system. Driving cools down a radiator, cool air and air flow would be increased if driving.

    @donmerrigan2362 Před 8 lety

    As others have said you need a retune to get any extra power from most mods. You've shown the cold air keeps the air into the motor cooler throughout rpm range. Cooler intake charge means denser air but you need to give more fuel to take advantage of it.
    I've personally logged a 1lb+/min increase in airflow by simply adding some metal tubing to move the intake filter from the stock location to down in the wheel well on a 1g awd dsm. More air = more potential power plain and simple.

I also took the car battery off and let it sit for a bit and reconnected the battery as when i started the car the fuel and ratio would change...now all i need is to tweak the fuel coming in because now i have more air than fuel got me? Hope it makes sense.

  • @DriftingDragon74
    @DriftingDragon74 Před 10 lety +3

    Cold air can increase power. Simple fact. However, exactly as they stated in the video the air actually going into the engine was staying pretty much constant. So, this only means that the cold air going into the filter wasn't cool enough to overcome the heat in the turbo and piping in the engine bay to make a noticeable difference. I'm not saying cai is worth all the hype but it has potential. Also, todays vehicles are computer controlled. Fine adjustments are made by the pcm/ecm to run similarly in all conditions. This cai can show its most noticeable effect on the street on a cold fall evening in naturally aspirated and carbureted vehicle. Then you can definitely see and feel a performance gain and could possibly even see the 20% increase they claim.

    • @Benedocta

    • @drewdude320i
      @drewdude320i Před 10 lety

      I have to respectfully disagree on part of what you stated here. While you may see a very slight increase to the horsepower at the wheels, you will never under any circumstance see a 20% improvement in power at the wheels with just a different air filter. 225hp / 0.8 = 285. That would be claiming a 60hp increase at the wheels in this instance. From a $20 air filter? No way.
      I'll give you an example. I have a 450hp V8 in my vehicle. It has two 3" air inlets and two filters (one behind each headlight) from the factory. A major aftermarket brand makes a "cold air intake" kit for the car. The previous owner included one in the sale, so I put it on for fun. While the car had more induction noise (less plastic to muffle noise), it was not any more powerful. And that's with a large n/a air-sucking motor. And unless the air induction system was unbelievably horribly designed, it wouldn't make any larger of a difference on a smaller car.
      Yes, having colder air helps reduce the temp of the intake charge and improve the efficiency of combustion (and thus create more power). And you're right that driving a car on a cold winter day vs a hot summer day makes a difference. But that's 40 degrees F vs 90 degrees F, and it's still just a slight improvement in power...maybe 2% tops. Going from 70 degrees F to 90 degrees F, even with "more flow," just cannot improve power by 20%. Truthfully, the only way a CAI is worth the investment is if you're just looking for style or more induction noise.

    • @ipo7596
      @ipo7596 Před 4 lety +1

      I think so. Watch Scotty Kilmer's explanation about CAIs. To summarize, I think it's the proper location of the CAI, preferably the coolest spot available in the engine bay. Then, I do think he mentioned about the computer getting reprogrammed so that it can register and detect where the new flow of air is coming upon now. Idk something like that. But I think the gains are almost negligible. I believe its like having a healthier lung, a clearer airway and cleaner, and colder air.

    • @mattbritton6222
      @mattbritton6222 Před 4 lety

      You should have an intake air temp sensor (sometimes called an air mass sensor or something) which tells the ECU the intake air temperature. The hotter the intake air, the less actual molecules of oxygen are getting in, so less fuel is required for the right air/fuel mix and the less power you can produce. I doubt it matters much between 15 degrees and 35 degrees, but I would think it matters if you feed in 50 degree air rather than 5 degrees.

    it also depends on how the engine control system is done is it a maf or a map sensor or both on my turbo volvo its a maf only and a single o2 sensor and the pod filter does make a noticeable difference as the bosch lh2.4 ecu system will see more air and add more fuel up to a certain point but not all ecu systems do this

  • @murmaider2
    @murmaider2 Před 10 lety +4

    I really do call bullshit on this "mythbusting". Air intakes on your average car are designed to be quiet, not "performance" or efficient. They often are fitted with baffles that decrease the diameter of the inlet pipe to quiet down the engine. If your car has a MAF (which it will if its fuel injected), a unrestricted intake will let your engine suck in more air which then will be compensated by the ECU which detects the increased airflow rate with the MAF and increases the amount of fuel injected. More air + more fuel = more power. Sure thats limited, but couple it with an exhaust, a bigger throttle body, a ECU tune and you can potentially make good power.

  • @shagtreez209
    @shagtreez209 Před 10 lety +6

    Couple of issues with the testing
    1. They were testing it out on a turbocharged engine that runs hotter than naturally aspired
    2. They are basically using a ram intake instead of the "true cold air" intake that sits below the fender.
    3. They were using it on a stationary car that was cooler with the stock intake and got progressively warmer when they put on the CAI, and a car will suck air cooler and more effectively at high speeds compared to on a dyno.
    4. They were using a Skyline as their test car! That has a pretty good intake stock, compared to a cheap Honda or Toyota that has a shitty one to begin with.
    But at the end of the day, is unlikely that you will see more that 5-10 hp from any CAI system. It isn't the greatest modification compared to money spent, but it will add a little bit of torque and a nice sound to your engine. It's not completely useless. Also somewhat increased fuel economy, but nothing amazing.

    Surely you need to remap the ECU with all these mods to work properly. Sticking a modded exhaust and air filter with the ECU in stock format will confuse the ECU resulting in lose of power. Remapping the ECU with mods will increase the power and performance. They all go hand in hand.

  • @BlueOvals24
    @BlueOvals24 Před 7 lety +4

    I think it really depends on the vehicle. On a vehicle with a minimally restricted system like that Skyline, a CAI won't do you much good. But my truck was pretty restricted with the factory air box. While I don't know for sure if the CAI improved my overall power, I did notice a big difference in throttle response and a notable difference in fuel economy.

  • @kevinyancey958
    @kevinyancey958 Před 5 lety

  • @joedoole3527
    @joedoole3527 Před 8 lety +41

    This is a bit deceiving. While your correct in the sense that slapping on random filters and tubes usually will not show power gains, a properly designed intake along with accompanying ecu tuning can indeed yield significant increases. The fact is though to take advantage of most aftermarket intakes that flow more air, you have to then go correct the ECU's map for air/fuel and timing to compensate for the additional air charge. We have seen gains upwards of 30 wheel HP on modern turbocharged vehicles after a simple cold air intake/retune. The gains are less on normally aspirated engines, but we have still seen gains of around 10 wheel HP on larger displacement 6 & 8 cylinder engines after a well designed Intake was installed AND the tune was adjusted accordingly. Tuning is key to making power, period!

      +Fuel4Torque kinda how I feel. Maybe this is a bad example, but take my computer. By putting a bigger fan on my cpu isn't going to make it run faster, it's going to make it run cooler / maybe more effeciently and potentially prolong it's lifespan, but it isn't going to run any faster.
      However, if I decide that I want to over clock my CPU, I would want to opt for more efficient CPU fan/heatsink for it, so that I know the temperature is efficient enough to not burn out by overclocking, or in car terms modding / additions that provide actual gains.
      When those increases are made, I know my CPU is getting enough air flow and at a hopefully cooler temperature than stock and won't break/melt/burn any parts from additional heat that's released in energy due to the actual gains (same for ICE [internal combustion engines]).
      Now, I'm definitely not a car expert and don't claim to be. I know just enough to be dangerous by being able to take my car apart, but not put it back together.
      Now, I understand ICE's function much differently than a CPU on a computer. I suspect the comparison can still be made, and hope someone can correct me if I'm wrong.
      I know ICE needs air, fuel, and spark to run or fire. I imagine the temperature of that air doesn't matter at the point of modification, more than ensuring flow of that air is maintained and to a temperature below the hottest temperature the engine can withstand before breaking.
      Again, I imagine this may provide potential longevity of an engine (disregarding water etc getting into cold air) as would a CPU, but not inherently make it run faster.
      I guess what I'm trying to say is just because something runs more efficiently doesn't always translate to an increase of performance.
      I'm sure someone smarter on here will probably prove me wrong, but that's my perception of it.

      @cheetahgaming3642 Před 4 lety

      on a boosted performance car the intake is already a good system... although the induction/flutter is great and it might be more beneficial for space... but retuning/flashing the ecu JUST for an intake will do nothing, changing other factors in the ecu would see a gain for ALL these filter setups. There is so much more you could do to this car besides a $20 pod filter and youd probably see 200kw-250kw for around $500-$1000
