I have used Autolite plugs for year and have always applied just a little silver anti seize and have never had any issues.

I think there may be more than a few phord owners who wished that phord had used something on their spark plugs.

That was the idiots who thought 2 or 3 threads were plenty to hold a spark plug in....

Ford Engineering at their best :whistling :

I use the nickel anti-seize and NGK plugs. No problems.
On the other hand I have used different anti-seize and spark plugs with no problems either.
Been using the anti-seize ever since I put a Champion plug into a new (clean) aluminum head, and it seized a few threads, and it was just installed finger tight, on the bench to check how far the plug extended into the chamber.

Yep, carbon build up on threads and crappy Autolite 2-piece plugs.
PIA changing those, lucky to see chatter on Mustang forum, only broke 2, and that was after only 30k.
Nickel high temp on everything now.

So if you are an idiot and over torque your spark plugs you will have problems. Hmm. But I can prevent spark plug seizure by revving the engine and replacing oil and filters on a regular basis using good oil. Hmm. Think I'll keep using the nickel anti-seize.

Im running a gen 2 hemi now. All the oil it needs every plug change😂😂😂

Neither has my ex wife, I suspect because she never had to change a set of platinum plugs after 100,000 miles or cared.

Not the way I would phrase it, but I agree with your sentiment.

Find it hard to believe copper can corrode more or enough relatively, to reduce conductivity in this environment.

i have been using anti-seize on plugs forever, it seems. just a dab is all i use, and i don't use a two foot cheater bar to torque them down.
with plugs that have been in use for eleventythousand miles, i run the engine to get some heat in the heads, then "feel" what it wants for the plug to break loose.
sometimes, i have "bad feelings" before the plug finally breaks loose...........

Anti-seize gives many people a license to slather. I can see why some people have issues when using it. More ain't better!

aluminum's number 1 anti corrosive agent is zinc. long term heating up and cooling down cycles can put moisture in the threads area = oxidation . if you are worried about it , use zinc chromates on the threads . i am pretty sure most [not all] come with a coating on them anyhow..

Exactly.

Oxidation of alum is almost unpreventable. Actually one of Alum best attributes is the hardness/toughness of the normal oxidised alum surface.
I believe what is the issue here is one of the combustion by products of every power stroke, among other things, is H2O, albeit its at very high temps, but nevertheless, it is still present. And I also suspect under the pressures the plug endures, some, even a minute amount, will find some H2O forced into the threads, where it will eventually condense. Electrolysis requires moisture, and a steel spark plug and an alum head are good candidates for electrolytic corrosion, and will overcome the alum oxide layer noted above. I also suspect the anti seize mainly fills the microscopic gaps in the thread interface, reducing the area electrolysis can occur easily and any space for any water to accumulate. Any OEM plug plated coating of the plug that reduces the electrical electrolysis potential between the two items has to be a plus.

Ok, maybe not a diamond, but its shiny.

Well thanks everyone, I learned a lot here as usual.

My original concern was to insure the plugs had a good electrical ground. A lot of baked-on crap
on the threads is not good for conductivity.

The points about thread seizing and about heat conductivity are enlightening too.

IMO anti-seize is one of those cases where less is more. I honestly believe I could dip a Q-tip one time in anti-seize, paint my entire car with it and still have enough to do all eight plugs. Plus have it all over me!

I have worked at several new car dealers and have seen every OE used brand seize installed in the factory (assumedly to factory recommendations) in the threads if left in too long, Champion, Bosche, NGK, Denso... The anti seize not only provides lube when its time to remove it it also fills the voids to keep those combustion byproducts out, I have never pulled a spark plug with anti seize on it that was seized in the hole.
