Do you use anti-seize for the spark plugs on aluminum heads?If so,what is best to use?
I only put anti-seize when they are long life platinum plugs, otherwise they go in raw. Been doing it this way for decades on motorcycles without a problem. My GM v6s that have 100K miles plugs always get anti-seize. I just get whatever copper stuff they have on the shelf.
I got this from an electrician at work for use on aluminium wire, I use it on my plugs too, seems to work really well...Penetrox A-13.
I don't have aluminum heads yet; but, I've always used Permatex Anti-Seize on my plugs. Never a problem.
You better be using it or you'll have a problem getting the plug out and hope you don't have heads like some Ford heads with hardly any threads or you'll be Helicoiling them.
I've always used it on spark plugs in aluminum heads. Use it sparingly though, it's conductive and if you get too much on the threads it will seep out and cause a dead short. Had someone do this to my Mother's mower once, took me a bit to find out what was causing the miss.
Yep, since the threads are tapered, no need the apply it to the first two threads. A little dab will do.
I use Permatex / Napa Anti-Seize Hi-Temp with copper on my spark plugs
had one stick, i use it on every thing in aluminum
I didn't know you had aluminum heads. Don't use it on iron heads.
