- Spark plugs are a very important part of your engine's operation. There are many aspects to a spark plug, in this video we cover four of the more basic aspects to a spark plug to help give you a little more knowledge in case you're planning to heavily modify your car. However, I would recommend running the OEM plug for most applications.
A very special thanks to Advance Auto Parts for sponsoring this video and providing the spark plugs shown.

Great video dudes! Thanks for having me on and hanging out at Humble Mechanic HQ!
Oh and what about indexing? (1of 3) HAHAHAH
You tipped them off! deals off!
Gears and Gasoline okay first round is on me. 😜
Running one or two steps colder is not just for boosted engines if you're planning on running high RPMs all the time like on a track naturally aspirated could use those types of spark plugs because I saw an old video from 1969 to 1970 Mopar talking about super tuning going into various steps to maximize horsepower without getting into the block and heads

When I want colder spark plugs, I stick them in the freezer before I install them.
Martini is a wino try this, has amazing results guaranteed, for about a quarter millisecond before its cracks to shit and you have to flush your engine. Lol
Excellent info. I changed my 3-cyl. Geo Metro to Bosch Platinum +4 and over 10,000 miles of checking mileage got 14 percent better mileage. Also, while going up a steep hill I passed a car. This was the only time in my eight-year ownership that I passed another vehicle. My son started driving it after my 10,000 miles with the car and it didn’t get such good mileage with the accelerator getting floored. Then he wrecked it during a gas crisis of 2008 and it proved cheaper to get a Porsche than another Metro.
I remember doing the same research for my car several years ago, this was a nice refresher
It's been really encouraging to see the progress on this channel. Keep it going, guys! Great content!
Good video, I've been planning my VW Mk7.5 Golf R build and have put very little thought in to the spark plugs. I'm aiming to double the stock 306BHP (currently running 380), and have heard of some guys running their Golf R's at 550BHP using Audi RS6 plugs. I haven't given it a lot of thought, but now will certainly be doing some detailed research.
Im a well rounded mechanic but i never dug into the books about sparks plug details. I learned so much. Thanks guys!
I love you guy’s honesty. I don’t know much about spark plugs beyond the basics that any car enthusiast knows.
I love the ngk vpower plug I have always used in all of my imports they always worth the $$ I havnt had any problems so far with them
This was really helpful. I've struggled with detonation and pre-ignition on my vintage Alfa, which taught me a lot of plugs, fuel octane, fuel-air mixture, and compression ratio.
Alfas sure teach us a lot
Tryin2fly09 can't find one that runs
Rusted POS go figure.
try a TVR
get your distributor checked = often 90% of the problem - re bush vac advance checked and dwell ! angel all so important a recurve with weber carby check for exchange reconditioned unit = good luck !
That effect on the sweeping shot of the gap was insane. I ran it back a bunch of times to watch it. Really dope. Keep up the awesome quality
It does make a difference. I just changed the older platinum Bosch plugs that had burned down to the porcelain with platinum Autolite plugs on my 1964 Ford Pickup. I changed out the old points with the aftermarket Igniter. It used to be a 3 on the tree and now it has 4 on the floor. I changed out the original differential from a 410 ratio to a 373 ratio. I also put in a set of headers on the 292 engine with duel pipes. I got the headers from LMC. I also replaced the original 2 barrel with a 4 barrel Holly. She flies like the wind.
When you change plugs on a Subaru, the best tool to use is small hands.
You arent kidding. I cant even get to three of the plugs on my Subaru.
Lmao mine is to easy ej22 sohc
Damn, so It wouldn't be a problem for me to own a subaru :D I love em subies, but just I'm scared from the boxer engine.
The number of issues my mrs has resolved in hard to work spaces in the engine is crazy 😂
Thanks for continuing with these wonderfully produced videos, and not doing vlogs like..... everyone else.
Thanks man for sharing, I like it.
Outstanding video!! After more than 20 years of turning wrenches it's amazing how little some "technicians" know about plugs. My hats off to y'all!! Great info
Probably the best video about spark plugs I've seen... and I've seen many. Great job!
You're firing on all cylinders in the making of this video😎
Great job!
It is also helpful to understand that boost = increased effective compression ratio. Therefore some people may use lower static compression in order to run more boost. But that means if they change to a colder plug to allow the higher boost but are running around town or doing a lot of idling, they could end up fouling those plugs and getting misfires, etc. Don't be afraid to swap out different kinds of plugs, depending upon the type of driving you are doing, with a heavily modified car.
So awesome to see you guys grow and an get sponsors! Been here since 20k and haven’t seen you guys made a bad video!
Everything about your guys videos is bright and uplifting. Great great stuff!
Most underrated channel ever
Ford galaxie Fan club! Hence why I must subscribe
nearly 600k subs, underated?
Platinum and Iridium plugs don't have those materials in the cores, only on the positive electrode and sometimes on the ground electrode. The core is almost always a copper-nickel alloy.
Cars Simplified it took me a half year to finally realize Hyundai Accent do prefer copper based sparkplugs. Really took me a long time to figure put what really wrong with irdium plugs.
Now i have new suv, i am forever sticking to factory specs set out by the books. No more aftermarket plugs and belts. I learned a lot from NGK irdium plugs and contentional crapbelts.
Nothing wrong with iridium, we use dozen each month is everything from 80hp to 1000hp. Truth be told it takes almost 20% less energy to "light" and iridium plug vs a copper plug. Plenty of tech papers on this nowadays to prove our dyno results aswell.
Trent-Catherine Hewitson please notice youre focusing on the spark plug itself, i was referring to the electrical and emission system, while it does work wonder, it creates more problem down thhe road. It is killing the factory ignition coils and wire.
Those metals are there to make the plug last longer (say, 100K miles) instead of the 25,000 mile plugs of yesteryear. As such, do NOT take a platinum or iridium plug and 'wire brush' it to clean it thinking it will make the plug last longer. It won't, and damages the plug.
The only benefit of running iridium plugs is the lifespan.
thanks for the great video!
is rare to hear people talk about spark plug, good information on this vid
Great video gentleman, keep up the great work! I always recommend your channel to my fellow car enthusiast.
Reading spark plugs is a lost art. This will help bring it back, old hot rodders used to tune their cars by reading the plugs.
Nice work on the video.
+boofighter I think there's more accurate ways to read how cars are running, but spark plugs is definitely an option.
Gears and Gasoline for sure, AfR gauge, O2 sensors, and a computer to adjust the ratios will be more accurate.
But if you were out at the track and did not have your laptop with you, reading the plugs could help you know what went wrong or why you were not getting the power you thought you should have.
Spark plugs and changing the heat range all falls under maintenance/tune up for me. I was taught to read the plugs and change the range as needed.
I have a wide band in my nova, data log it, I still pull the plugs and read them. People are getting lazy today. Instead of learning something and trying to retain that knowledge they think they are always gonna be able to have google answer it for them.
Gear and gas the subject here are spark plugs and to read a plug is NOT an "option".
spark plugs ? whys he getting und-------- oh .. subaru lol
My exact reaction
I had the same thought
It can be done both over and unde. I do over.
I love this channel so much ,I swear this is film making at it's best!.
Thank you for the accurate information! I've always ran copper with 50% larger gap on my MK3 Supra's I had before. Changed them every 15k miles. I quickly noticed smother top end and better low end torque vs the double platinum stock plugs, ran slightly higher boost and upgraded intake and exhaust (stock manifold and turbo).
The Supra was old and was DD in Chicagos salty winter's. But I always make sure the grounds where clean and even upgraded them with new cables. Coil packs where tested and where very healthy well within spec.
I don't know how you guys don't have 7 billion subs u make insane videos which are high quality and really enjoyable to watch
What?
Do you think my little pony tweens are into cars or something?
The rest are from the You Tube deleted !!
The masses are not connoisseurs, this is true in every walk of life sadly. Hence, more people's attention is drawn to things like Kardashians and "lil pump" as opposed to genuine artists or experts in interesting fields.
great video man, it covers good information, educative and clear. you earned a sub :)
my Jetta is about to hit 40K miles in just a little over two years. I am planning a full PM tune this spring. I learned something from this video ! Thanks for making great videos ! Also shout out to HumbleMechanic for the VW love !
I...I am speechless. Good job and keep making this type of videos.
Awesome video guys! The only thing id like to point out is that you don't read afr from a spark plug that is just pulled out of an engine. They will almost always be lean/hot/white because an engine idles or cruises at 14.7:1 AFR which creates the most heat in turn creating the most power (to a certain point but that's a whole other debate). The proper way to read a spark plug is to go wide open then shut the engine off while still wide open (typically after about 5-10 seconds of WOT) that way you will get a proper reading from the spark plug (you can also tell detonation and timing from plugs this way). Just thought i'd point that out to anyone who actually wants to read plugs (I prefer a wideband O2 myself) anyway great video and keep up the good work! Also I love your gridlife and track videos, as a time attack driver it's nice to see some media coverage for the sport!
I run NGK in almost everything I have owned, also I check, clean and/or replace with each oil change.
@Mad Adam new beta generation doesn't / people before millennials
Great insights on this commonly undiscussed topic.
Thanks for the video!
This is truly helpful video! Thank you a lot for the time spent making it.👍🏼
Never used auto light only (ngk)

"It's kind of a necessity to keep it running" referring to the importance of spark plugs.
Drop the "kind of". It's not kind of a necessity. It's an absolute necessity.
Diesel?
I'm actually looking for some spark plugs right now. There are so many options and different types. Thank you!
One of the Best video i have ever watched about spark plugs 👍
Can we get another just drive video, :O pls
The real question is; can you really remove subaru spark plugs from underneath the car? 😉
I tried. Two hours to check one plug and find out it was okay. And that was the easy one to get to.
subframe is in the way on some models ..its not that hard from the top ...move the airflow/maf sensor &airbox on one side& battery on the other side ..then its alot easier ..ive had 4 Subaru (gt legacy & forrestor )
Rick I did it in my wife’s 2002 Impreza RS, and was a pain.
Now she’s got a 2013 Subaru XV, and need to do it soon. I’m not looking forward to it...
What’s the difficulty level on this car?
Removing Subaru plugs is a pain in the tucas because you have the coils to remove first ! Not fun
Did the spark plugs in my 02 Wrx Bugeye in like an hour. Maybe an hour and a half. Super eazy... Don't get what all the fuss is about 🤣 People must not have the correct tools or any mechanical knowledge. 🤦♂️
damn that shrink effect with the spark plug in the zoomed shot was just cooool :)
you guys are gonna be viral from the quality of this video I can tell
...and remember, if you ever drop a plug onto the hard ground from height (>1.5m?), toss it.
Double Platinum plugs are for running coil packs that run two plugs for coil because one plug first neg and one plug fires pos
That is not how waste spark works sir...
@@demarcodraper4266 Discounting the first few words of his statement and substituting the word fires in place of the word, "first," that is exactly how a waste spark system works.
@@VashthStampeede kinda but you are completely negating why it's called waste spark. It is true the that both spark plugs function as part of a completed circuit but that would not be possible if you didn't have a difference in pressures in the companion cylinders. The block functions as the ground to the compression cylinder and the wasted spark but the denser chamber gets the spark because it is the path of least resistance.
@@demarcodraper4266 In a waste spark system, both plugs are fired at exactly the same time. The plug that fires near the end of the exhaust stroke is wasted, thus the name waste spark. However, the plug that fires into the compression stroke does the work and is not wasted. You do not need two sparking plugs to complete the circuit as a bad coil can often fire only one plug and cause a misfire in the companion cylinder. As you stated, the engine block is ground. Electrons are negatively charged. So, the engine block is full of electrons looking for a place to go. A positive charge means the absence of electrons and is very attractive to the electrons at ground. Voltage is only the difference in potential between positive and negative. But in an ignition system with such high voltage, lack of electrons, even a positively charged surface with a difference in potential can effectively complete a circuit. This is often called a floating ground. I'm getting tired and starting to ramble. Please forgive me. Back to the path of least resistance, it's the cylinder with no compression. And, the spark finds the compressed mixture and lights it too. It takes 80 volts to jump a 0.001 gap at sea level, one atmosphere. Multiply by the size of the gap and the compression ratio and you will find the kv necessary to ionize the gap under pressure and create the spark. Twenty-five to thirty-five percent of that is used to maintain the spark once initiated.
@@VashthStampeede I believe you are right sir. Resistance creates a higher intesity spark but a short duration so it makes sense that more spark energy would be used jumping the gap in the denser combustion chamber.
Fantastic, best technical info about spark plug, thanks for the upload.
Can’t believe how much I just learned. Thanks!
I've found , through experience, the Autolite sparkplugs are garbage.
zhbvenkhoReload they sure are. Walmart brand garbage
Garbage?1000%garbage ...everytime u go to the store their try to sell u that aulite shit brand
Get either NGK OR DENSO IRIDUIM PLUGS
Same with Champion.
Bad idea to use the same plugs for everything, especially on some cars. Engines with twin coil wasted spark will wear the ground electrode in months... also how can you even "accidentally have the threads come out with the plug"?? The threads and stuff are made directly in the head cast. I've only ever heard of cross threading when *putting new plugs in*
What am I doing watching this video? I drive a diesel car. LOL
You KNOW you want to swap out to a petrol engine
Great vid man. Goes to show anyone could always learn something new ! Thanks.
Have a good one.
THat was seriously entertaining, Informative & Incredibly well done! Seriously, I'm subscribing just because of this video!
Somebody found a way to make spark plugs entertaining😆
what about resistors and none resistors plugs?
Non...none is nothing...
WTF! Yea that beard is in his way lol
Brilliant videos and they’re really engaging. Keep up the good work man!
awesome stuff. Thanks for taking the time to do the plug research, its definitely helped me and cleared some things up.
Can you do one on "what is two step"? Please?
Tryin2fly09 oh no we got a car elitist here
+Tryin2fly09 you're a """car enthusiast"""
guess you've never heard of keybangs then
About that "sparkplugs wont broke your engine" a too hot sparkplug can make holes in the piston among other issues.
Spot on. They can stay hot enough to cause pre-ignition and misfires
Thank you for the good information about spark plugs. It was very helpful.
Good job on the video, I didn't really learn anything new but I was just checking to make sure lol Thanks for posting, it was very well done!
You missed a very important aspect - resistor or non resistor plugs!
I run no resistor plugs on my chev and dodge. Work a lot better for my application
But can your car do thiiis?
For only 399$ you can get the best racing chair on the market

Ignas V 😂😂😂 la whyyyyy
Who touched my SPAGET!!

PPPPEEEEEEEEEWWWWDDDDSSSSS
Learned a lot in 8 mins, another great video
Awesome video about a car topic I know so little about! Merci beaucoup!!!
if you are running a msd ignition do not use anything other than copper plugs or you will damage your ignition box.
69NOMAN69 u must have a bad ground
thats straight from msd
Irrideum are recommended joe !
ngk plugs in american engines will run to hot thus taking the temper out of the piston return springs
Another great episode, thanks guys
Wow! Really happy to see someone doing their homework BEFORE putting out a video! I grew up working on cars n trucks then went to college to work on aircraft... I think I kinda know what I'm doing. Lol. You are now very knowledgeable when it comes to spark plugs! Great work! Keep it up man! Don't EVER be afraid to admit you don't know something... its FAR worse to fake it and give bad info. Sub'd
Now I am a sparkplug expert
My dad's dog's cousin did a spark plug delete on his Civic, he said he got a 20 HP increase and a 3kg weight reduction
[ Insert Name Here ] what in god name
What Spark Plugs work best in a ‘96 Ford 7.3L PowerStroke diesel? The ones in it now need replacing, I’m tempted to try E3 ???
Killed it as always!
Well done video. Good detail, finally understand the heat range issue and why.
Any diesel owners here??
Glow plugs will set you back way more than spark plugs! I remember paying for one glow plug, and thinking I could have done a complete tune up on the same money!!
alright lets see how you fill 9 minutes with spark plugs
And non-sensical drumbeats in the background. GARBAGE!
Wow I learned something new thanks guy's I will check my spark plugs more often
Another great video! Easy to understand as always 👍
NGK enough said the rest just hype ..
Why would you ever want to work on Volkswagens for 15 years?
Job Security?
They pay specialists like the man in the video very well.
I miss working on only Volkswagens
I work on Chrysler/Fiat products now and my money is waaayyy down
Because the money is good. They are engineered to need service at the dealer (or at least a mechanic). so the shadetree mechanic doesnt want to hassle with it.
to cheat vehicle inspection test?
Great video. Been trying to explain to a friend why I chose grade 6, which is 2 steps colder for my highly tuned wrx. This explains it perfectly !
@Flapping Flight Or, you could just see how high they bounce. Hotter plugs bounce higher.
That FD was soooooo beautiful 😍😍😍
Think $14 for a plug is expensive? They're over $100 each for many airplane engines, and you have two per cylinder to replace.
Pix2GoStudios well we dont own airplanes we own cars. So yeah $15 its expensive for plugs
4 cyl vs 8cyl
FYI this video is about CARS.
When It comes to fixing a car. a $13 spark plug is cheap
Mad Adam that’s it ? My spark plugs are 20 a piece
Very interesting, this has made me want to study spark plugs now to learn more about the heat ratings and gap choices etc.
Actually great video. Didn't expect to learn much but I did.
Whoever disliked this has no soul
33 ppl .... :(
It's an entire video about spark plugs. You can't be surprised by dislikes.
slick_ej6 😂 no they are in too electric cars😂
well, using weird units of measurement might be the reason
+slick_ej6 - I dislike cause I have no money! 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
Sorry, but manufacturers spend their time looking for the cheapest components to do the job, not the best.
it doesn't take much to meet the criteria of US auto manufacturers. Often, especially in the case of Chrysler, they'll go with the same manufacturer (Federal Mogul) for a broad range of components (air filter, oil filter, bearings, fuel system components...) rather than just a single item because they get a better deal that way. Sometimes it works out, other times, not so much: www.reuters.com/article/us-federal-mogul-recall/federal-mogul-recalls-parts-in-some-chrysler-vehicles-idUSTRE6BR2V920101228
Um, not sure if that applies to every manufacturer. Volvos hate having any other parts of the ignition system that isn’t oem. If you try to upgrade even when going for big power, the car really doesn’t like anything without a factory plugs, coils and even cables.
@Dutch Power😸
jeffel80 right, that's why bmw's are made of mostly plastic and leak like crazy, how nissans have weak and terrible automatic transmission and defective fuel injectors and so on, but ThEy MeEt ThEIr CrIteRia.
@@rex_s80 most European and Asian car manufacturers are like that
Solid stuff. Great video that was actually incredibly informative.
That's an amazing video guys, well done
Moral of the story. Run diesel.
Fuck diesel !
John Drohan they don't
Just... Never run AutoLites.
all my cars an bikes have them i run 275s in my corvairs only thing that will last in my kw100 dirt bike my 56 chevy has to have them ,,ngks now they are junk
NGK is top of the chain when it comes to spark plugs! What the hell are you talking about lol. Your KW100 should have a NGK plug in it haha!
ngks wont run in it ..an its a ke100..... i run autolites or ac deloco in all my 16 cars an even in my honda rebel ngks are junk to me they foul to easy
Lol i hope you realize that all tuners recommend NGK plugs right? Some tuners wont even touch your car without switching it to NGK plug's. I think you may need to research a little bit my friend. You have have issue with the greatest spark plugs in the world for a reason, As in maybe you dont gap or install them correctly idk, But clearly something is wrong if you can use a junk plug like AutoLite, And not use a top quality plug like NGK.
Lol look me up kid. My name is Scott Gatto, And you have no idea what you are talking about.
This is a great video. Thanks for posting.
Thank you for these information. Very helpful :)
Very insightful. Thanks for the info. Great vid.
Excellent teaching!
I love your channel keep up the good work!
Thank you! I enjoyed that!
Great video, thanks for sharing!
Pretty impressive video and well done for all the effort fella.
Very informative. Great job. 😊
I love your videos!!! Great info!
