Anti- sieze on NGK TR55 plugs
 

Yes or No?

Re: Anti- sieze on NGK TR55 plugs
 

I always used anti seize with non taper seat plugs. They make a crayon like anti seize that I used to put a couple of swipes on the threads, when installing on aluminum heads.

Alum heads yes, otherwise optional IMHO

Chevy LS so yes alum heads. I did not install the plugs that were in this car, so I don't know if anti seize was used,or if they were over torqued. I had to use a 1/2 breakover to pop them loose.and I dont want to go through that again.

You must suspect that anti-seize was not used when you posted. I do not have the experience that you do, however I was taught that dissimilar metals should use anti-seize. 1/2 breaker , wow my father always told me not to go crazy, "they are only plugs not head bolts" LOL.

Yes, in aluminum.

Sparingly, just like the elbow grease used to tighten them.

I understand the anti seize because of 2 different metals, but I thought that it enhanced poor grounding of plug to head. Maybe I dreamed it.
