Why NOT Copper?

[TORNIT07]

When installing new spark plugs why can't one use copper anti-seize on the threads & part of the plug that protrudes into the cylinder head? I see that Nickle Anti-Seize is what everyone is using.

I was browsing the copper & it recommends to use on spark plug threads right on the bottle. There were two different types with the difference being one had a slightly higher temperature rating.

Nobody carries the nickle type around my area, not even the Ford dealerships. I had ordered a tube online but it ended up in hostile hands...long story.I don't really want to wait for another tube.

So, I have my new Motorcraft plugs, Motorcraft PM3, Lisle Broken Spark Plug Extractor Tool (wasn't going to buy it unless needed but decided better to have it on hand ready to go if required) and Dielectric grease. All I need now is the anti-seize & I'll be ready to begin.

Don't know about the product but one thing to consider is the thermal expansion rate. If the product doesn't state safe for aluminum heads I wouldn't use it.

I used the anti seize in the small pouches from Autozone when I did mine. Says it's good for aluminum heads.

That's interesting. I've never heard of that before. Every single bolt I take out, no matter on which car, I always use copper grease before it goes back on the vehicle. Wonder if I've ever done any damage over the years.

I went ahead & bought the Nickel anti-seize, just to be on the safe side. Funny thing is, even though everyone says to use Nickel, it doesn't specify "safe for aluminum" anywhere on the package or tube. It's Permatex brand. Maybe on their website...but how many people bother to research online before just using this kind of stuff?
