Spark Plug Anti Seize

[gaphono]

I am changing my Plugs soon in my C6. What is your advice on using an Anti Seize product on the Plug Threads? Is this required?

I have always used anti seize on all spark plugs that I install.

Gm recommends not using anti seize, and to instead use a small amount of engine oil on the threads. You definately want to use one or the other.

AC/Delco plugs have a coating that negates the need for anti-seize, and in fact, anti-seize will create problems, fouling, poor torquing, etc.

C4C5 Specialist covered this exact topic at a seminar last summer. He was pretty empathic that the drop of oil path is the way to go.

C4C5 Specialist..... still agree with a drop of oil and no anti-seize on new spark plugs?

HI there,

ABSOLUTELY NO ANTISEIZE.

Torque to 11 ft lbs.

Allthebest, c4c5

Drop of oil, doubt antiseize would hurt though

[ChuckG]

Yeah, it will. It will foul the plugs and prevent proper seating and sealing.

Wanna see mine from the mechanic who didn't head GM's wishes?
