Spark plug threads

[dan88911]

Is applying anti-seize on spark plug threads a good idea?

[Bob Kontak]

Sure. Just a smidgeon on the threads.

Copper based is best

Just read somewhere on this forum yesterday that Porsche advised against it as it reduces conductivity thus decreasing the spark.
Personally I never use anti-seize on spark plugs, but it is a matter of personal preference.

I use just a little Permatex Hi-temp copper-based anti-seize. Easy-peasy. Have noticed no ill effects on ignition. But I can see how that might be an issue if you use too much. Then again, copper's a pretty good electrical conductor . . . .

Dude, do you ever leave that poor car alone?

Thanks, I was thinking a very little would not hurt.
However, I will follow the bulletin.

Thanks again.

damn, I just did my plugs....guess I'll wait until the next 15K checkup. Dry, indeed.

I use anti-seize on the threads but a miniscule amount. I've been doing it for many, many years on all the cars, including the 911s.

I GUARANTEE that if you use too much, the plug won't spark. Been there, done that.

I had just read a thread on that issue the day before and a quick search returned this pic posted by a member of this forum. Gotta love it when info is still fresh in your mind!

Interesting comment in this month's Panorama Tech section. Guy having trouble getting a plug out and the moderator sez........use a bit of anti seize next time.

[zippy_gg]

If you ask 10 people you will get 10 different opinions.
In the end it is what makes you comfortable that matters.

This is a tech bulletin from NGK regarding anti-sieze. Spoiler alert - they say not to use it.

[DRACO A5OG]

Well ngk is what I use, so I will make it so :P

[Tippy]

You do not use anti-seize due to the plating on the spark plug threads.

I used a dab of copper antisieze last change; 27mpg on the hwy and not a blip to rev limiter. I won't see those suckers again until 180,000 miles but I reckon they'll come out.

The Porsche owners manual also says change the oil every 12,000 (or 15,000) miles and CASIS says shift at 2100rpm. I change (and shift) at 3,000. Lotsa choices.
