Good to know about the boots/springs. Thanks for sharing.

Just FYI: So called "copper" plugs are actually made out of nickel. Copper is too soft to use for spark plug electrodes. Iridium has lower electrical resistance than nickel and also has much better thermal conductivity (Google it). Platinum is much worse than either.

You will probably get spark blowout at .032. I had the NGK BKR7E standard plugs in my Cruze at .032 and I got blowout. They did perform better than the OEM plugs with the platinum ground electrode when they were gapped at about .027.

It is also inadvisable to use anti-seize. They will actually lubricate the threads, as you said, but that is a bad thing because you will over-torque the plugs. The torque numbers are set without anti-seize lubrication. Most modern spark plugs come with an anti-seize coating already on the threads that won't affect your torque values.
