Jim, what plugs are you running? Those cars can be very particular about their plugs. If it's not happy, they do kind of like to burn them up, but it most likely won't cause any additional damage. if it does. I've burned up several, but that was back when I was running Champion's in the thing. It's had NGK's for years now and I haven't lost a plug in long time. FWIW, when it has burned one up before, it doesn't ever seem to damage anything else.

Why one burns up before another, there doesn't really seem to be any rhyme or reason to it.
