Quick question. I'm replacing the spark plugs on my '90 this spring - is this the right type of anti-seize for the threads?

Thanks.

Since your concern is steel/Al looks like the right one.

The argument against anti-sieze has always been it hurts or stops the plug grounding to the head. The copper based anti-sieze actually helps the grounding. I would research if this type conducts electricity. Dan

Will that stuff take the heat? Why not buy the anti seize for the right job. Packets of the stuff right at ck out in any auto parts store

That product conducts electricity. You just want to use a "dab" on the threads only, it doesn't take. If it is on the porcelain or near electrode misfire can occur.

Should work fine. Been using that stuff for y ears and yes, less is more.

I use that exact stuff myself.

OP: To apply it, first put a little on a finger tip - a tiny blob, maybe a 5mm "dome" of it. Then with one swipe down toward the tip end (along the axis of the plug, in other words), allow the threads to scrape off that entire blob in one swipe. That is just enough to prevent seizing, and because aluminum makes an excellent conductor of both electricity AND heat, don't let worries about electrical integrity concern you in the least.

That said: Resist the temptation to load up the threads around the circumference of the plug, thinking 'more is better'. There are cases where plugs have actually backed out to blow out of the hole, taking the last thread or so of the head with it! Not good. ALSO, you don't want to get any of anti-seize on the porcelain insulator. Keep in mind the anti-seize makes an excellent conductor and will ground out the spark if it is smeared on the porcelain portion of the spark plug, OR accidentally gets inside the rubber boot. Same thing: spark flash-over grounding out the spark.

two schools of thought on the subject, but most newer plugs have a nickel plating which is supposed to eliminate the need for anti-seize. HOWEVER, while it may be overkill, I still use it. I would suggest using a product specifically designed for this purpose, and not some generic anti-seize compound.

recommended product...



while most don't do it, IMO, it important to torque the plugs to spec -

That Champion Aerospace seems to be hard to come by in Canada, I will keep looking though. Otherwise I will just go with the Permatex.

I appreciate the help everyone, thank you.
