Damage control

I always use antiseize and so far so good. Always torque to fsm spec.

Me too. :shrug:

And I would definitely use antiseize with an aluminum head. When you go to remove the plugs it is so easy for the threads to gall to the plugs and strip the hole out.

I always use antiseize and so far so good on.. well... 9 Jeeps. Always torque to fsm spec.

Me too. :shrug:

With a 30k plug change no antiseize is needed and can eventually cause issues in the long run,nothing mentioned about using that stuff in the FSM.


If you must use antiseize on spark plugs you should be using the copper version,the silver stuff reduces the electrical conductivity thus reducing ignition performance since those threads "ground" the plugs to the engine.


Oh and by the way using that stuff you need to cut the torque by at least 40%,all those torque ratings are stated for dry threads unless otherwise stated(like head bolts).

also the NGK plugs says on the instruction that it doesn't require antiseize due to a coating on it.

I've got about 10k before my next change. I shall proceed without the antiseize at that time. Not alot of experience with aluminum heads. I do use it very sparingly.
