Scotty Kilmer have a question I saw a video that a guy put carburetor cleaner where are you can use gumout or any of those products he let it soak for a few hours then remove it with a turkey baster never saw this done before is this is a way you can do it or is this a bad thing what do you think
Scotty Kilmer Hi Scotty what brand of spark plug is best NGK or Bosch ?? Many thanks From Ireland
Scotty Kilmer Don't die on me Scotty , I still need help with my car...lol🤔. Great video , keep them coming. I loved your how to deal with haters video , you killed it bro.
What are your thoughts on colder or hotter spark plugs on a modified vehicle?
Scotty is the best automotive diy channel, hands down. Straight to the point.
thanks for the tips dad
Disappointing Barry I wish
Im gonna start calling him dadd too ctfu
It’s daddy not dad
He gave you a new dad that likes to tip? Commas are important.
It's imposible to watch an Scotty Kilmer video while being sad.
Abel Mauricio Except the end of this video 😂😂
Abel Mauricio why?
Like Confucius said "Choose a job you love, and you will never have to work a day in your life"
Abel Mauricio I was sad at the ending when he talked about dieing.
Until your dream job turns into a living hell... Time to explore something else I'd enjoy doing.
please don't die, Scotty
well, we all die one day, LIFE, no one gets out of it alive.
Scotty Kilmer who do we listen to when your gone seeing how your so automotive smart?
Scotty Kilmer I dont know, Bruce Forsythe must be about 150 by now.
ChrisFix can't be older than 30. Phew
Ar Fr lmbo really? I watch him too. You cant trust everyone on youtube but Scotty and Chris
Scotty, can you show us how to change spark plugs on a Tesla?
MRsjovealek you are dumb
so are spark plugs dummy!
Kill it before it breeds
xD
vuaeco lolz
Scotty your information is priceless. When it comes to hands on stuff I've pretty much "been there done that" because I was an outside machinist before I ever touched a car. But I love the challenges of working on them "never a dull moment".I'm slowly collecting more automotive tools and absorbing information like a sponge. Love your videos and your enthusiasm keep up the good work!!
A video on spark plugs?
*Shocking!*
I see what you did there.
You could say...
(•_•)

(⌐■_■)
This plug for OEM was a spark of inspiration.
No you couldn't.
I changed my NGK Iridium plugs for the first time at 225,000 miles! Fabulous plugs, most cars never even make it that long.
I changed the spark plugs in my camry (recently traded in for a highlander) at 65,000 miles only as preventative maintenance. I was very surprised at how clean they were. I probably could have used the factory spark plugs well into 120,000 miles. Since I had them out I went ahead and installed NGK brand iridium spark plugs.
"Before its too late!"
enters room full of dead bodies
He should do one of those outros at a morgue :D
i lost it when he did that it's not normally what scotty does lol
Remember to vacuum out the well before taking the plug out. Don't want to drop grit and dirt down into the cylinder.
Shit...
Wipe off before removing, the wipe around hole before installing new ones. All good.
Would 3 in 1 penetrating oil ruin the engine when using it to loosen up an stuck old spark plug ??
Hi Scotty, yes iridium plugs will last somewhat longer BUT the insulator around the centre electrode is made of the same ceramic material used in basic copper core plugs and this insulator often fails well before the plug gap burns out. The insulator is the weakest link in pursuit of a long life plug. I often use basic copper core plugs instead nowdays especially if the spark plugs are fairly easy to access, they are alot cheaper and still last 30,000 to 50,000 miles. Copper is also a better conductor than Iridium and will give a bigger better spark.
For people who might not know, the gap on spark plugs might also need to be set, as some of them are gapped to a standard size because they fit in multiple cars with different ignition system and engine specs such as compression ratio, supercharged, etc. I generally regap mine from 1.1mm to 0.95mm when buying them, specifically for my car so it runs better.
"its a load of baloney" lololol love this guy
I put Bosche platinum which were rated for my Subaru EJ25 engine and experienced terrible misfires. I then put in NGK Laser Platinum and the misfires were a thing of the past. Both were "rated" for that engine but the NGK was the only one that worked.
I had the same thing happen to my Frontier's KA24DE. I first thought the distributor cap/rotor had gone bad, replaced them, and the misfiring was still there. Ended up pulling the plug wires until I found the one that made no difference in how the truck ran, then replaced all of them with NGK's (which I had originally used on the 100k replacement). Lessons learned!
I don't know why you cannot resist or avoid to watch SCOTTY KILMER'S technical video...people became addicted i think to your technical and practical tips...because as you said too many people and some company saying bullshit talks to boost their sales. ..thanks a lot Scotty...(beam me up-Start Trek)... and there is one good old saying in the Star Trek movie by Scotty ...it doesn't mean its old you have to throw away...old is gold...Ok , Kilmer thanks a lot for the video tips...
I have an old Volvo 850, and definitely make sure you get the right plugs for your engine. This one was designed with copper plugs, but I used iridium plugs and it instantly ran worse than before I removed the old coppers.
I used NGK Laser Iridium plugs on my 05’ Tacoma Prerunner 2.7L.
60k miles later still running great.
Did you put lube on the threads? I did idk till scotty said not to hope I don't damage anything
I just changed the plugs and wires in my '09 Wrangler, after 106000 miles. Amazing. I remember changing the plugs in my old Beetle every couple of years.
I have to smile at every one of his intros...
Scotty, i'm old too...lets be sure heaven is our home now!
yes amen I have ran so many different kinds of plugs and the oem type is the only way to go.
I’m feeding the algorithm… this guy has great, useful, and accurate content (entertaining too)
That ending really bummed me out. Scotty Kilmer for life! Your videos always pump me up and as 91B in the army, I learn a lot from your vids.
Thanks Scotty. Legendary stuff, you have everything covered for a car lover.
Next year will be your golden (50 years) anniversary!
2018 (the year you are referring to) has been so far so good for Scotty
Scotty is the best mechanic on CZcams !!!!!!!
I bought a used, one owner Chrysler Town and country with 192,000 miles. driven nice and easy, and mostly very well maintained..except the spark plugs. Guy said they'd never changed them and the van still drive beautifully. It had Champion double platinums, and the gap was about twice what it should've been!! Not sure how it was still running that good.. I replaced with the same plug with barely a noticeable difference. Amazing they lasted that long
Scotty's videos may be short, but he always gives really good advice.
Thank you Scotty!
For anyone's consideration, looking for that sweet spot, my experience and research, Iridium are great and I've found Autolite XP brand to be great and priced right on eBay and I put them in both my vehicles that have just over 100,000 miles and lots of life left.
Now for two of my friends who's cars have almost 200,000 miles on them, we opted to get just the autolite single platinum(double platinum are pricey and crazy design not needed) that don't last quite as long but were very affordable at AutoZone $2 each, since their cars may die before we have to do the plugs again.
Now don't trust the auto store clerks at all that say plugs are already pregapped.
If the gap is off from the factory, they won't spark right and it only takes a few seconds to carefully gap.
They say that because you can damage the center electrode if you put any force on it while prying the spark arm open more if more gap is needed while adjusting so just be careful when gapping, bend the arm with the gapping fork, avoiding the hard tempered fragile center electrode.
I like to torque to 20 lbs as a general rule to make sure I don't over or under tighten the plugs.
Don't forget to compare the old spark plugs to the new ones to make sure they didn't sell you the wrong ones, ones too long into the cylinder hole could hit the piston and ruin the engine is what happened to a friend of mine but he was on drugs and lost in his mind-shouldn't have been working on his car, glad he finally got to rehab and off that mind trapping stuff.
Just take your time and address any odd things that might come up, one friend had a lot of oil down the valve cover plug hole that was near the oil filler cap from people being sloppy when adding oil to the engine. For that, when we removed the plug, the oil went into the hole and then we cranked the engine so the oil could spray out the hole with a rag over the hole, if we had just put the new plug in, the oil could have hydro lock damaged that piston.
If you really want to, you can apply antiseize grease, but remember that most quality spark plugs come with threads metal designed not to rust seize and Scotty and most say not to because this and over-tightening could strip the newer aluminum cylinder threads.
You can use any plain oil or grease, as a cheaper option.
Also remember that these increase the torque by like 20% you are applying so reduce your torque setting.
Don't make the common mistake of being lazy and forgetting which wire goes to which plug, label them first somehow if you need to.
If the vehicle has a cap and rotor, inspect and consider replacing that is affordable too after you made sure the engine is running right with the new plugs installed to know that went well.
Hope this helps someone
Hi Scotty. I've been watching your videos for YEARS and you've helped me so many times. I wanted to ask if could one day make a video showing how to change an oil pan gasket on a Ford Mustang 4.6 V8. I know it's a little involved, but there are absolutely ZERO videos on CZcams for this repair. Thanks Scotty you rock!
I prefer Bosch Platinums, they stay nice and clean.
electronicsNmore completely agree, only plugs I use on my cars.
Not for gm's
jbody 4
Who says? I had a GM, never a problem.
Same here, never an issue.

I used platinum plugs in my gy6 150cc scooter, and Kawasaki Jet Ski also.
When I had 88 turbo Supra that called for OEM double platinum plugs I tested out other plugs, iridium somehow started to melt and for fun I put it AC Delco copper plugs that I gapped with machine shims and added 50%+ to the OE gap spec from .032 to .050 like a mad man. From that I noticed very slightly better spool at low RPMs and what really surprised me was that the engine got extremely smooth above 6k RPMs. Sure they last about 15-20k miles on a strong ignition system, but they could be changed out in 30 minutes with no hassle on the Supra. I also make sure to leave the stem as flat as I can, because if you leave it at an angle when it wears it going to quickly go out of the gap you set.
I half expected you to go into a sales pitch and sell me gimmicky plugs. Thanks!
When it comes to torquing delicate items in the 10lb-20lb range like spark plugs or manifold cover bolts, its best to use a beam style torque wrench because you can visually see the torque occurring. I've seen people use the click type and ruin threads because they kept turning, but the wrench didn't click and that can happen for a number of reasons. Click types are great though for things that need to be torqued at a higher lbs-ft, especially in awkward positions where looking at a beam type wrench would be difficult like caliper bolts or wheel lug nuts.
Thank you so much Mr Scotty GOD blessed you
My car originally came with Bosch platinum plugs. So I just stick with those whenever I replace them. Never had any issues with Bosch plugs

How to use spark plug
We ALWAYS recommend putting in the factory plugs back in.
Would have bought the wrong sparkplugs without this knowledge! Thanks a ton as always Scotty!
Scotty you're an angel .
Thanks for the tip to get the wire gap tester
Scotty's neighbours must love him....
Thank you for the videos Scotty....keep em coming.
This guy is golden!!!!!
I love it. It is not only very educational but also entertaining. I do not get enough of it. Thanks and keep it up.
Scotty you are awesome.
Great info...and may I add that beginner mechanics only replace one at a time to ensure the right spark plug wire goes back in the right position..crossing a few will lead to lots of trouble!!
Scotty is my hero
1969 Corvette Stingray restored by your own hand? Much props Scotty Kilmer, i have a 2018 turbo civic sport but i am so jealous right now :) !!!
platinum 4 tip bosch plugs gave my cars better mileage and power, noticeably so instantly when I put them in. Scotty, I've been working on cars for 40 years now, since I was 16, now I'm 57. 12 years in industry as a repair garage. including diesel and truck repair.
Lots of people have noticed that Bosch spark plugs work poorly in Toyota 4 cylinder engines. Denso or NGK is a safe bet and cheap too.
It is the same thing for some German cars. My dad's Porsche 944 T factory plugs are Bosch copper plus. But it runs better with NGK copper plugs.
I use Bosch Double Iridium Plugs in my 2010 Corolla S...and they work GREAT!
Dima Aryeh bosch are junk in every car.
+Nate Avery. I disagree...I've had nothing but luck using Bosch Plugs in my Cars! I've taken them over 150,000K and they still look and work great. You also need to spec the proper heat range for plugs to use in your individual applications...which is true with any Plug. Some Plugs are Cooler, some are Mid Range and some are really Hotter. In my case, I am using their top range Double Iridium Fine Wire Plugs...they're in a medium heat range of about 6 or so. My Vehicle runs very smooth and quiet on them, and the engine sounds as new as the day the Car was bought! The original Denso Plugs that the Car came with were lower end quality plugs...they worked okay, but the components like the Ceramic Insulators were deteriorating and the points were beginning to level out...but minimal fouling. However...I checked my coils and they were all fine, so I proceeded to the plugs. My RPM Needle was bouncing around between 580 to 800 RPM while the Car was fully heated to lower RPM. Often when I'd push the brake or come to a stop at a light...the vehicle felt like it was about to quit and idle out, and then it would bounce up again. I recorded a before and after on my OBDII Diagnostic and compared. When I put the first set of Bosch Plugs in...the Cars Engine improve tenfold and ran so quietly and smoothly compared to the old Straight Iridium Denso's. The idling was much smoother and steady, and the RPM Needle stopped bouncing up and down. The near shutdown at low idle also ceased! I recently decided to replace those plugs with newer ones 125,000K later...and they still looked new and fabulous! So I took the newer plugs and put them away in the toolbox. I'll go another 25,000K or so before I replace them with the newer ones. My power is good and my fuel usage and mileage improved greatly! New Corolla's generally come with Denso or NGK...whichever Toyota has readily available on the Assembly Line at the time of manufacture? Maybe the plugs you were using just weren't spec'd appropriately for your Vehicles application, or maybe some quality control issues...I really don't know? Toyota recommends Iridium Plugs for the 1.8 L4 Engine...but doesn't specify any particular Brand in their Owner's Manuals. All you can do is switch them out until you find one that works really well with your vehicles requirements. But seriously...I've never had any issues with Bosch Plugs. My next choice would likely be NGK's if I wasn't satisfied with the Bosch Plugs! Just Sayin"
Had bosch spark plugs in my skoda when i bought them and it ran like crap. Replaced them with the factory champion plugs and now it runs great. Needless to say, just stick with the factory plugs for the best results.
i trust ngk, went with iridium laser welded tip.
They made my focus misfire so did bosch platinums had to go to motocraft.
the end tho... man i m glad i found this guy,i love it
I dont mind the other kind of spark plug gap measuring tools. ive never had a problem, and i like how i can adjust the gap with it as well. to each his own though. Good video!
With some modern high boost, high performance engines its best to be checking the sparks every 40,000 miles or so. The higher cylinder temperatures and higher output ignition systems these engines have can wear down iridium plugs faster than you'd expect. This is particularly the case in high boost downsized engines that you would find in many european cars.
I always use a torque wench for anything delicate. For some reason what I think is 25 foot pounds is more like 80. I always grab the ratchet at the head to reduce torque but it never seems to reduce it enough
use less tongue
HAHAHAH WOW I completely missed that
See it is true the tongue is the strongest muscle ;-)
My car had original spark plugs that lasted up for 20 years and 190,000 miles on it n started up pretty nicely with them
Scotty, how about a video on interpretation of what the spark plug looks like?
one thing at a time.
Can worn/old sparkplugs also lower your mileage significantly?
ngk, can't go wrong
Autolite is fine for Fords, but they really shouldn't be in Hondas, Toyotas, &c.
Spot on regarding NGK. Replaced mine every 10 000 miles and the gaps had widened by 0.02 mm at most between services. Could probably have run them for 20 000 miles before replacing them
Did you say you replace your plugs every 10K miles? You know they can go like 80K no problem.
Tool0GT92 maybe copper ones, but why even use them
Tool0GT92
Replaced... I no longer own that car. In fact, my current car doesn't have spark plugs. As for going for 80k - with fuel injected engines, yes. Not so much with carburetted engines.
That cat is a great animal actor. Right on cue.
Definitely get your spark plugs changed regularly. I got a tune up at 200k and changed out the original spark plugs but one of them fused to the engine! It still works for now, but once it stops we'll need some expensive repairs.
Thanks Scotty for making this video.
Iridium plugs are excellent and i have been using them for many years and they last a long time with better performance & economy.
The down side is the delicate thin electrode that goes through the core of the plugs can break off like it did with me when i took the plug out,thankfully it did not do any damage to the bore.
The electrode on the iridium is very thin compared to a regular plug.
Regular plugs are more robust than iridium ones that's the only negative to iridium's,but apart from that iridiums are great and i would not go back to regular plugs.
Scotty is a sweet man.
I want that triumph. That's badass
Love the show Scotty, appreciate your explanations that help educate the ignorant.
Performance Spark Plugs do exist but they're like $100 a pop and they require an aftermarket ignition system as well which costs anywhere between 1000 and 2500 USD, AND these are only available for few specific cars.
However, those are made for special cars that are made for racing for example, the idea of them is to have shorter ignition times to make more consistent power which is only noticeable in racing basically, they're like the sequential gearboxes, they're made for a specific thing for specific use and usually specific vehicles.
But, like i said, to have any actual use from the racing plugs, you need an entire system swap and also most likely an aftermarket ECU which will set the timing and such correctly so it's not exactly worth it unless you have already spent enough money on your car to have literally everything else.
Edit : Just to throw a "running joke" (which is a real thing though) there's actually Racing Batteries as well, they're lighter and have higher momentary power, thus they're pretty much perfect for racing.
I love your videos brother. Am ordering tools on amazon so i can change the spark plugs myself thanks for the help on all these videos
Hey Scotty. I work at Auto Zone and I get customers with vehicles that originally use iridium spark plugs yet a lot of customers don't want to spend the money on them, some customers are so cheap that they buy copper spark plugs instead. I try to inform that on how iridium, platium, and double platium work, yet customers claim to be a "mechanic" then they come back claiming I sold them bad spark plugs. Is it because they bought the wrong type of plug? Are they spark plugs just spark plugs. A lot of your videos have helped me do my job better and really hope you can help me with this issue. Thanks. love the videos.
irridium plugs last longer, but any plug made for that car would make it run fine in the short run, unless they messed up the job breaking wires or knocking vacuum hoses off
Thanks mr. Kilmer! Greetings from Holland!
My 2011 dodge avenger is one of the few modern cars that uses copper plugs, the ngk v-powers. I’ve just stuck to what the manual says and change them every 30k, and yes they do look visibly worn after the 30k.
good morning Scotty
Great tips Scotty!
Scotty youre too funny man... thanks for all the knowledge man.. appreciate it buddy and im sure i speak for everyone
You are the man Scott
I’ve found my passion watching your videos and learning Scotty thank you I didn’t even know that I loved working on cars this much I simply type in ______ my problem here and Scotty Kilmer and I always get Results thanks brother
*How to pick the right spark plug and replace it in 5 easy steps*
Look in car manual.
Drive to auto store.
Buy the same ones mentioned in said manual.
Drive home.
Replace when engine is cold.
OEM is always best for spark plugs no doubt! Unless you are doing boost mods and need colder ones or a smaller gap.
If you've got a Honda, the NGK copper plugs are widely recommended. They cost $8 for all 4 at Advance after coupon (p20). They won't last as long as iridiums, but work better if you don't mind changing them every couple of years. Just don't buy Autolite plugs....for any car. They don't call them "NeverLite" for no reason.
best end so far :)
Put iridium plugs on a 2001 Outback and it burned the electrode right off. Went back to regular NGK just plain old NGK regular and they work the best. Same thing on a Harley Road Glide iridium plugs suck went back to original ngks.
I was one of those guys who bought those baloney plugs...learned my lesson the hard way.
According to the nice gentleman that I spoke with at Federal-Mogul, all of the Champion 'precious metal' plugs are made in the USA, their copper plugs are made in Mexico. Just a little FYI for anyone who likes to buy American made stuff as much as possible (like myself).
I have an interesting predicament, My '08 Honda fit has a misfire in cyl #4 (Ive checked the plugs and the ignition coils) and will only run rough in the following gears; Park, Neutral, and Reverse. It idles just fine in Drive.
Thanks, Scotty. You're my hero. 😘
You sir are the dad I wish I’d had…better late than never
I have a 2004 Pontiac Montana with 222.000 miles and they were factory AC Delco normal plugs
My 04 corolla ran like crap when I replaced the densos with Bosch. Went back to densos and was good again.
have a volvo v70 and use volvo OEM never a problem
You should do a video replacing turn signal bulbs
Scotty thanks for all u do to help us. Can u hit on the Toyota Tacoma 4x4 one day. I love mine. You the Man......
Looks warm there. Great vid Scotty. My car uses platinum plugs but I heard they can go long distances too.
Scotty, i have a 2004 jeep grand cherokee 4.7 limited. Im getting like 12 mpg...ive went through everything.changed plugs (used the factory recommended), looked for vacum leaks, 02 sensors. tire pressure, fuel filter, some seafoam... airfilter, belt and tensioner.cleaned my iacv,cleaned my throttle body and used a new gasket, replaced the tps not long ago either..my brakes are not sticking either..I used a screwdriver to listen to my injectors but i have not removed them to clean them yet. I am not getting any check engine light and my actron scanners say no codes found. Checked the maf sensor too. Not long ago i did a computer reset re learn as my last thing ive done so far... This mileage is killing me. Thank you in advance!
have a pro like me hook up his dealer scan tool and analyze live and mode 6 data to see how efficiently it's running first. then check harder stuff like worn trans later
Great video as always and really liked your comment about not using antiseize. Many today believe its a must when just about every plug manufacturer says not to lol. I guess old myths die hard.
The manual on my Honda says to change them like every 5000 miles, seems to often for me.
Great Vid Scotty. Thanks for the tip on the Wire Gauge, Ill have to pick one up. Reminds me of a pitch pipe hahah. Woops Ive been putting a lil copper anti seize on my plugs as Ive run into stuck plugs in heads before.
Thank you Scotty
WOW!! intro with The Reverend Horton!!!
I've got 2003 Nissan Pathfinder with 96,000 miles and original NGK Platinum spark plugs. The car runs fine. Change interval is 105,000 miles. Thinking putting the same plugs for another 105,000 miles to go.
awesome, didn't know Scotty was a crazy cat guy too. I saw that same cat on another of his videos.
Scotty Rocks
