Anyone do this ?
Plugs need a good ground, I have read to use oil but that doesn't seem like a good idea. I do on my aluminum heads.

Read a bulletin years ago from NGK that said NOT to use the copper as it makes the plug hard to ground in the head and that Alum. anti-seize was better. I use motor oil myself....

I use copper anti-seize on the threads only. I'd like to see whoever claims that anti-seize on the threads hinders the ground provide some test information. I'm sure the contact between the seat of the spark plug, the aluminum spark plug tube, and the cylinder head provide plenty of ground even if the threads were completely insulated by the anti-seize.

I've also used lead and aluminum based antisieze, whatever is on hand. No problems with grounding.

Been a mechanic for over 35 years and probably installed a couple thousand plugs with just a couple drops of oil on the threads . Gus

If the plugs are R&R regularly oil is OK. For really long intervals, it becomes carbon and will engrave aluminum threads. Anti-seize reduces heat transfer, but apparently not enough to matter.

1. Anti-seize
NGK spark plugs feature trivalent plating. This silver or chrome-colored finish on the threads is designed to provide corrosion resistance against moisture and chemicals. The coating also acts as a release agent during spark plug removal. NGK spark plugs are installed at the factory dry, without lubrication or anti-seize.
Anti-seize can act as a lubricant, altering torque values up to 20 percent, increasing the risk of spark plug thread breakage and/or metal shell stretch. Thread breakage can sometimes involve removing the cylinder head for repair. Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental.

Just to support the "dont use antisieze" movement. as someone mentioned previously it also prohibits heat transfer, This overheats the plug and causing pre detonation and premature plug failure.

Well, I've used anti-sieze (nickel) on spark plug threads for over 30 years. Iron heads, aluminum heads, flat seat, tapered seat, domestic and imported, small engine and large engine. Haven't had one problem. You have to realize what the head material is and how anti-sieze affects the torque but I would think any competent mechanic should realize those two factors when installing plugs.

Every time I have ever removed a spark plug and the threads came out with it the reason was because they were clearly installed dry. Not such a big deal with hot rods and such with short removal intervals but the newer engines with double iridium that are supposed to be in the engine over 100,000 or just lazy people running others that long is where they get siezed in the head and ruin the threads. On customer cars I always use something because you never know how long they will try to run before they ever replace plugs again. A mechanic with any feel for what he is doing can tighten it without stripping it.
As for heat transfer, if anything it would make the plug run colder not hotter, only silver conducts heat faster than copper, the copper will transfer heat faster as the particles fill space and make more contact with the steel on steel or steel on aluminum.

I don't use NGK, so their coating is irrelevant to me. Why spend the big bucks on them, when AC's work just as well at 1/4 the price.

I run NGK and have never put any anti seize on them. I dont do a incredible hulk impression when I tighten them either, however. Anti sieze has it place but I wont put it on anything that I have to remove at regular intervals. Its a mess and gets on EVERYTHING...
