Should I use antiseize on my spark plugs when I replace them?
Most threads on spark plugs designed for aluminum-head applications are precoated to reduce the risk of thread damage. If you’re in the habit of applying a drop of antiseize compound to the plug threads before they go in for added insurance, you might want to reconsider this practice. One vehicle manufacturer warns against this practice because antiseize acts like a lubricant and may allow the plugs to be overtightened — which can damage the threads. Their advice is to reduce the tightening torque on the plugs by 40% if you decide to use antiseize on the threads.

Yes. Be careful not to get it on the plug tips. Threads only. In 60k, you will be thanking me very much
It sure beats having a plug seize in the head or breaking the plug off when trying to get the plug out(after it's been cooking in your engine for 4-5 years)
I've used anti-seize for years and years and years etc.... I don't even use a torque wrench(but I guess rookies should). Common sense rules here ya know?
