Use silver on the threads everytime I inspect and/or change plugs. Just mnake sure you don't get any down by the tip.

You don't have to over tighten for them to get stuck.

Steel threads/aluminium heads...Anti sieze is a must IMO.

Damn. I've been changing spark plugs for over fifty years and never used anything. I probably won't change my bad habits now. Too late.

Always used the "colloidal copper" C5A on my plugs (or anything mating with alum & heat) Regarding the heat range thing, theory is that the plug tip will be hotter because the anti-sieze blocks heat transfer from the plug to the head. Could be, but I've never used a lot of it or given it any thought. Plugs come out ok and bike runs great, good enough for me.

I think you should use anti-sieze on every bolt threaded into anything aluminum. I use it all the time. Doesn't really matter what kind - ANY anti-sieze is infinitely better than no anti-sieze

There was a discussion last week over in the Hacked & Trike section about Harley not using anti-seize on the 103 and as a result, so far about a half a dozen owners have reported galling their pugs upon removal!

What is even more galling (couldn’t resist the pun) is that some dealers are saying that the Harley manual doesn’t call for the plugs to be inspected at the 1k, 5k & 10k inspection and that the book does NOT require anti-seize; which is totally incorrect, the book states: inspect and anti-seize!
