Anti-seize on spark plugs?

[zoidberg444]

Mine has regular copper core Denso plugs. I change them every 20,000 miles. I never bother. Normally just put a tiny toot of WD40 down when I break them loose. Then wipe the residue away with a rag before i put the new ones in. I find a bit of carbon builds up on the threads and they are very... dry. But i don't bother with anti seize. Never had an issue.

i find this interesting that you do not have problems with pre-detonation. on my honda i tried to run silver plugs and had all kinds of issues. the computer controlled ignition has the dwell resistance programmed in for platinum/iridium, and silver/copper core have almost no resistance resulting in an early spark. idk

on the anti-seize: the main reason i believe they don't want you using anti-seize is that people slop it all over and it can short out the electrode and drip into the cylinder and cause other issues. it is usually conductive, and could cause electrical issues.
saying that, i have always used anti-seize on spark plugs. i put a tiny drop on the threads of a plug, then i take a second plug and spin it around the threads if the first plug spreading the anti-seize all over the threads of both plugs in a very thin layer. never had an issue. i have however had to remove a seized,broken, and stripped plugs from a head. i'll take the risk.
