For any doubtful peeps... ngksparkplugs.com/en/resources/5-things-you-should-know-about-spark-plugs
I literally just did this... now what.
@@snes06 If it were me, I'd pull them back out, clean the threads, and then reinstall them. I know it's a huge pain, but if @MrSubaru1387 says to do it I'd go through the trouble.
Thanks, I have an 05 legacy 2.5 non turbo, and it's giving me lots of problems right now ¿
@@snes06 I used to put antiseize on the plugs and the disgusting mess it left on the plugs and on the plug hole threads when the next plug change came around. Not good for electrical grounding and probably doesn't help the heat rating either.. Last time I changed the plugs after watching this video I sprayed starting fluid down the spark plug pipe holes to loosen the carbon and build up and used an air gun to blow out the crap. After a few goes and screwing a clean spark plug in to see if there was still residue I got pretty much all of it off. I also used a cheap camera bore scope to check the results and it was pretty clean after about 3 or 4 goes. And if you do it make sure the engine is completely cool. I'd be getting that crap off there, the torque can be 20% more than it should be due to the reduced friction with possibility of breaking threads and it's bad joo joo for an alloy engine. As Mr Subaru says, do it right, one and done.
I actually work for NGK, and I endorse this message.
Thank you for sending me spark plugs so that I could get my car running again. I don't understand why people have issues with NGK, they've worked great for me so far!
Can y'all lower the prices back to what they were in 2020 ? 😆
Can this fit my Chevy Cruze Ltz 1.4L?
@Therealgame1 NGK is a brand, they make a specific model for your engine.
@@yung_megafoneI don’t think anyone does at least in the the Japanese car communities. Ngk or denso is what they use as oem.
I feel like I just got scolded by the school principal
Would be nice if they printed it
on the box. Nothing much, just a short “do not use anti-seize”
They do
@ashishpatel350 they do not. If they do its only on certain boxes. I have caes of multiple different cr plugs not one says it. 😂

They spell it out in their install instructions. But then again, Honda's service manuals call for NGK plugs and call for anti-seize and provide a torque spec. So who is right? I suggest both are right as long as the fastening torque is adjusted accordingly.
Also make sure your NGK plugs are authentic.
I've been changing my own Spark Plugs since the 1970's when the gas was leaded & changing the plugs was a part of normal, regular maintenance. Spark plugs always had to be changed on the lawn mower, snowmobile, & motorcycle as well. I never used "anti-seize" on any of them. I have seen other videos on changing the Subaru plugs & often the "Backyard Mechanic" will use the anti-seize when changing them. My advice - Watch Mr. Subaru & go with what He says. I wish He lived in Vermont!...
So just a tiny bit then? Got it!
NONE
😂
Wish I came across this last week 😂
So I take it that is a no on the anti-seize...
Yeah for NGKs
Thats krazy I been using ngks for years and have been putting anti seize 😬
Clear and direct video of the day 👍
Thanks for the video, I previously worked at a Honda dealer and they forced us to put anti seize on spark plugs. I had to fight back and print out the ngk tech bulletin that says not to do that.
We switched to graphite spray as online showed that this is what aviation industry used. But as well we sold a spark plug service and ngk said that wasn’t recommended because you can’t replace the crush washer
Well I already put anti seize on my NGK iridium’s when I swapped the plugs in my LS400 1UZ (because I’ve always used anti seize), now I will know for the future and when I do the spark plugs on my GS300 2JZ, not to add anti seize.
I just wish I came across this video sooner because I had no idea 😅
My car runs great though! So as long as they will be good I will change them again early in 30-50k miles and correctly so it then.
What does Toyota's service manual say?
@pdubsyyyy I don't have the GS anymore I have a civic Si now, but I have my 93 LS400 still and it runs perfectly fine still.
And check your gaps, which NGK also states to do as well.
Well I fucked it. I put anti seize on my NGK spark plugs in my Sambar last summer. Oops. Perhaps two wrongs made a right since I didn’t use a torque wrench anyway 🙁😭😝
💀
It's OK, some issues can fix itself or can be pushed under the bed so no one will ever notice 👍
Dude so did I!
Anti seize is mostly aluminum so unlikely to be an issue with conductivity.
Newer plugs are nickel .
When aluminium heads were becoming more common , there was a problem with steel plugs , and many people used antiseieze.
No longer necessary or recommended .
For what years though?
@Sum Teng Wong if spark plugs are not silver looking, ie steel not nickel , use antiseize if head is aluminum.
@@inverseuniverse5727 just did mines today, and hour it took. It's silver, it's weird cuz when I turn it, it stays firm for a while and I can keep turning it a lot more and I'm afraid to turn more in case it cracks.
@Sum Teng Wong slowly go out and in , 1/16 of a turn at a time with wd40 ..
I do because I live in Florida. I've had multiple seized plugs from the nickel corroding and getting stuck.
Real lifesaver! Thank you!
I've been telling people for years! Nice to hear it for the first time from someone else.
How is ASe certified since the 90s and I used to tell mechanics this and they would always get real sick but now it's good to see it's popular
It's also more likely to loosen up with all that lubricant on it the last spark plug I saw that blew out of a cylinder head that had a ton of anti seize
Honda's service manual specifically calls for NGK plugs and specifically calls for antiseize.
Is it an aluminum block? I'm unaware
@@steveeab2364 Yes. Aluminum head.
Curious
@@IShould.veKnown Iridium NKG plugs, a small amount of anti-seize, and torque to 13 ft-lb. That's Honda's stardard recommendation. Their torque spec accounts for the anti-seize. If you didn't use anti seize, and stuck with Honda's 13 ft-lb then it would be not tight enough. (NGK have a whole other service bulletin related the problems of not tightening spark plugs enough. Apparently they'll overheat in that case, and cause misfires.) NKG recommend no anti-seize and give an angular tighting spec. Either should result in the correct tightening IMO. And copper/graphite/aluminum anti-seize is irrelevant insofar as conductivity is concerned. All are good conductors. Without measurements and evidence I just don't buy that it affects resistance significantly. Especially when the plug itself already has 5k ohm of resistance built in. Personally, I follow Honda's spec because I've never seen any evidence that it's wrong. I also like the insurance it provides when it comes time to remove the plugs years down the road.
@@jptrainor Thank you. As a Honda owner/maintainer I appreciate the insight
Damn thanks. Put the beating on infinite loop please, I deserve it.
Flashing back to many thread repairs in aluminum heads*
This was really interesting, but I have just one question… is it OK to put anti-seize on an NGK spark plug?
Thanks for that info!
love this tip, thank you!!!
Great advice, I had no idea 😉
You can't stop me!
but how will Auto Zone sell all their goo packs!?
That's interesting, I work on motorcycles and ngk is used on almost everything, and pretty much all modern bikes have aluminum heads. I have never once put anti seize on spark plugs, but another tech who came from an older car shop swore by using it on all spark plugs. I personally never found a need for it, the only spark plugs I've had trouble getting out are ones with damaged threads from improper instalation or over torqued by the customer.
Some service manuals say to put a touch of oil on the thread.
Talk about passion!
Excellent educational content and video!!!✌️😎👍👍👍👍👍👍👍All The Best!!!
Great advice for any spark plug too! 👍
Actually, there is a percentage that has to be taken away from the torque when you use anti-seize on threads. I believe it's somewhere between 10-20% you dock away from the dry thread torque. Coefficient of friction, simple Google search will point you in the right direction. As far as NGK having a special coating, I don't know because I don't run their plugs. But in the 10 years of turning wrenches professionally, I've never had any issues using copper based anti-seize on the threads of the plugs.
Y’all are torquing your spark plugs?
Hand tight plus hit it with the impact for good measure. XD
Well you save me and a bunch of others a butt load of money thanks
I just did mine yesterday without apply an anti-sease thanks!😬
I'm glad my parts store never said a dam thing...nor the box. Is my subi broken now
No.. Just don't do it again. Lol
Anti seize on spark plugs is like putting antiseize on a ground cable 😂 Rookies!
1 year later I still feel like I'm being scolded. 😂
100% agree! While doing a tuneup on a friends car, he tried to hand me some anti-seize and I told him NGK spark plugs don’t need it. I told him to research it.
Class says, Yes Mr. Subaru
soo...I just did this yesterday....what do i do...take them out and wipe it off?
Thank you very much for this video, I was just about to replace spark plugs on my Subaru Legacy I gen from 1994. Replaced, WITHOUT anti-seize compound.
W SUBARUs
I've always used Red lock tight
That’s good information now I’ve got to go change some spark plugs
I put anti-seize on all spark plugs and I've never broken one. Never really had an issue either. I also don't torque spark plugs with a torque wrench
lmao i replaced the plugs in my truck with these ones and i didn’t put anti seize on them and i was worried they were gonna get stuck so this is good to know 😂
I use to work at a Honda Dealership and couple of the technicians would give me crap because I would never use anti seize on plugs 🤣
Ford Triton has entered the chat:
Doesn't run NGK plugs. Is a garbage Ford. *Triton leaves chat*
@@MrSubaru1387 😂😂😂
Great tip!
So glad this vid was made!
I'm in Australia and my Gregory's manual which is much the same as Haynes manuals, says to put anti-seize on the spark plug threads and also to put RTV silicone on the Water Pump Gasket as well as the Threads of the water pump Bolts!
All completely wrong.
Actually some engines, have a water pump bolt that goes through the w.p housing and requires rtv on the thread to prevent leaking. Rare occasion but it is a thing
@@timwinslade7462Yeah some engines but we're talking about the Subaru boxer engines specifically.
Thank you.
Thank you very much just bought some for my 2010 Honda civic
That’s a good bit of info
I've had zero issues with putting anti-seize on spark plugs for decades - works really well for long life spark plugs. I never use a torque wrench for spark plugs - always go by feel for safety.
Good info
Thanks for the tip, on another topic, what battery do you recommend for 2007 SOHC 2.5L NA engine for Northeast resident.
Thanks
Thank you for the information I did not know that
Totally agree with you years ago I used to be the anti-seize man I think even Denso states the same thing for their plugs
Yep.
Wow, my '90 Pontiac had aluminum heads and I always installed it's spark plugs w/o anti-seize on them (because it wasn't around / popular then). Then all I hear, anti-seize this anti-seize that, and thinking that I'm old fashioned and technically out of touch... Now, here I am trying to be "professional" and putting anti-seize on my '02 Subaru's spark plugs...
Now I just feel like a merry-go-round that everyone's enjoying playing with!
🤣👍
always put anti seize on the threads of an ngk sparkplug. got it.
So what about on older iron block engines?
If I dont put it on and the plugs ruin my head, are you going to cover the damage?
put new plugs on my 2020 STI. used copper antiseize like a scrub. Got the plugs hand tight, then turned about 2-3 inches worth with the rachet. I know not to crank down on spark plugs, so i only did a little bit of turning after it got snug...even tho it felt like i couldve kept going. but i didnt know about not using anti seize... how screwed would you say i am??
Is this for all brands?
I thought anti-seize was a no-no for any car with an O2 sensor. Or was it with a Cat? They usually go together anyway...
I’ve been working on cars for 20 years and have never put anti seize on any spark plugs and never had any problems removing them
Good to know😳
Doesn’t help that autozone GIVES the anti-seize for free when u purchase the plugs.
I pefer using red loctite. ( obviously i say this in jest)
Red loctite, imagine🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
Loctite's great... 😅👍
Thanks! I seen that brand at autozone and got it. Just changed and used it on my parents car, hopefully it lasts a long while!
Jesus this strap on lovin dude just loves the sound of his own voice.
But totally agree. Lol
Wish I had a seen this BEFORE I PUT ANTISEIZE on my NGK... 😮
Thank you kindly sir. I'm glad I was being cheap lastnight at autozone and did NOT purchase any antiseize...
Can still use my 1/2" impact though?
Too late, the anti-seize is now on there forever 🤷🏻♂️
Someone grab this guy a snickers 😂
Use impact? 😂
This is good info! I recently pulled the plugs on an EJ251 (doing head gaskets). They had anti-seize on them and came out hard. One was VERY difficult to turn out - I thought for sure I had galled the threads. Had the machine shop check and fortunately threads just needed to be chased. Maybe anti-seize is a carry-over from when 100,000 mile spark plug routines first surfaced years ago?
On another note, what do you recommend for spark plugs? I was on the NGK website this morning and there's many choices. It''s only 4 plugs, so a few dollars more is ok with me if it's worth it for the long run. Car is a 2002 Forester, non-turbo EJ251. Thanks Mr Subaru!
Thank you 🙏
Damnnnnnn you know how many years I’ve done!!?
Damn I done messed up
What about dielectric grease?
What about a cast iron head would anti seize be okay
Thanks!!!
I got an oil leak on there I need that anti seize and dielectric grease too late honestly they've been working just fine on my honda
Same as Denso.
Woops I put some on there but only a tad bit very thin coating on one part of it
I never use anti-seize on anything like that I've never done it but now I have a big reason not to ever do it and I did not know that
Huh, didn’t know they had some specific corrosion inhibitors.
Cause I’ve always used a tiny bit of copper anti seize on all my plugs. 🤷🏻♂️
It's a stupid debate that has been going on for a while. I don't put it on any plugs just because I don't want that crap all over everything.
That being said... I've put it on hundreds of spark plugs with 0.0% I'll effect, even with NGK.
Just because a manufacturer says to do it one way, doesn't mean it is guaranteed to be the best decision.
There's no debate. You don't put it on them. The spark plug manufacturer says no. End of "discussion".
ngksparkplugs.com/en/resources/5-things-you-should-know-about-spark-plugs
@@MrSubaru1387 I have never used anti seize and have never had a problem with them not earthing or with corrosion or a plug being stuck. don't put shit on them , don't over tighten them 🤷
Dont use the copper that is for exhaust stuff. Use the gray one. It makes zero ill effects but what it does do is keep the plug from seizing in the head.
Big inch nitrous big block guy… have always used it…. Never an issue… pull plugs after each hit…. 3 times a night maybe …. Never heard this
Does this apply to aviation?
How do you really feel?
The graphite, copper and aluminum in antiseize are all good conductotrs. They won't affect conductivity between the plug and the head. And the liquid component is squeezed out at the metal to metal contact points just like dielectric grease is squeezed out when used in electrical terminals. The torque is affected.
I can see why the strong emphasis on “do not” repeatedly happens.
It’s insane how many fools do this on every nut and bolt, not everything deserves anti seize or “never” seize. If the manufacturer did not put it on… then it doesn’t need it!
I believe this applies to any other spark plug
Just one more reason why I don't like using NGKs...
Thank you for the reminder 👍
We went over this in school, and I followed this advice for a long time. Then I ran into a few original NGK plugs that were incredibly scary to remove, including in a subaru. I did some research, and I did come across some articles about the non-conductive nature of antiseize filler affecting the path to ground - BUT, people have been putting anti-seize on plugs for decades with no issues, and I have never seen this cause an issue on an NGK plug. Can anyone confirm that this has EVER caused an issue for this reason? I am always careful to apply just a dab starting a couple threads up to ensure it doesn't find its way to the electrode. As far as torque, assuming you are capable and have experience torquing things, have a feel for how the crush washer crushes, etc, is there really any legitimate reason NOT to put antiseize on these plugs? As far as I can tell, there is no interaction or anything, at least with the copper antiseize that I use (the stuff that comes with O2 sensors that I save). I've never had an issue with under or overtorquing when doing it by hand instead of with a torque wrench, and I've never seen it cause comebacks for misfires of any sort. I am not at all trolling here, because I really do want to know if there is any confirmation of a problem. As I said, I was on the other side of this argument previously. Now, every plug I install (unless it's on something crazy and exotic with super specific plug installation instructions) gets antiseize.
Under torquing is also a relevant issue with regards to anti-seize. +/- 15%-25% from your torque value (dry) can cause huge problems with nuts walking off - primarily suspension components.
I think over-torquing is the big concern. The lack of friction can cause the plug to get so tight that it breaks or pulls the threads out of the head. Installation torque has to be reduced when the thread is lubricated.
Are all spark plugs NGK? Can you put anti seize on other spark plugs? Never thought of the ground issue either.
We only really needed anti seize , when engine first came out and cars started using aluminum heads . most spark plugs were steel threads . the steel plugs would sieze in the aluminum heads .
Now almost all plugs are nickel type and no sieze to aluminium.
I use anti sieze and never had a problem
Seemed a little less like a tech tip and a little more like an ass chewing 😂
