anti seize: yes or no

[Hood]

I'm changing the spark plugs on my 2012 Fusion.
2.5L 4 cylinder engine. The plugs I'm pulling out have 87k miles on them. Should I use anti seize on the new plugs or not? (Motorcraft SP530 iridium)

So you are threading steel plugs into Alum heads for sure I would use anti seize , lube between dissimilar metals is always a good idea

As Neil said. AND, don't use the aluminum product, use the copper one, otherwise you're putting aluminum on steel anyways and they're not the best friends.

Thanks, Neil and Jimynick!  Mission accomplished the correct way.
