About time for another oil-change and new set of TR6's on the motor. Being that most of the shops and retailers recommend changing the plugs so frequently on these motors when they are modded; does anyone use anti-seize on their plug threads?
Anti-seize on plug threads?

absolutely.
I do..............................................
I do on all my cars, I dont go crazy with it but I put enough to coat the threads.
yep
Definitely.

You better!
Steel plugs in aluminum heads mandate anti-seize on the threads.
If you don't use it, next time you pull the plugs there's a very good chance you will pull the threads along with them.

Good article. At 30k I'll be replacing with OEM plugs. I wonder if they have the same coating? Even if you use anti seize you should be fine if tighten to 13 ft lbs.
Yes, for sure
I always use anti seize and dielectric grease
Well F+++ me, never thought about that, I always use it especially in aluminum head/iron block turbo deals, but also am careful not to over tighten.
I think most performance plugs probably have that coating :shrug:
I know the NGKs or Autolite race (non-projected tip) seem to always have that.
Thanks for posting Catmonkey :beer:

a little bit of anti seize doesn't hurt. Don't put a lot and also don't tighten the crap out of the plugs.
If you're not sure use a torque wrench. I've always hand tighten them to the head then do two 1/4 turns to compress the washer (on new plugs) and you're set. Done it this way for years never have a problem.
If reinstalling plugs and the washer is already compressed hand tighten and do 1/8 of a turn.

You don't have to worry about ^^that, if you simply follow para 1 of this.
Spark Plug Installation Instructions
I prefer to use antiseize and just torque them properly.
Agree
Anti-seize will affect your torque values FWIW.

Your correct! I should have added..."properly" meaning, "and I just use 15lb/ft for NGK TR6's with anti-seize", which applies the 30% torque reduction philosophy for using anti-seize. The 30% reduced torque differential, when corrected, falls within the 18-21.6lb/ft torque values for the TR6 (14mm) plugs and I've never had a problem. :bash: on wood!
