Thanks so much for the response. Definately will ensure that the heads are cool, and I am also a fan of never seize for plugs. Likely stay with the Bosch, but I have used NGK a bit in some ITA cars.

I do miss the 535i, there are still motor cycle guys in the North Georgia mountains that recall some guy in a big black BMW closing right up on their tires in the tight turns.

I'll let you know how the plug change goes! And I'm going to go with an upgraded air cleaner at the same time, likely a K&N.
