    M42 Plugs

    I pulled and inspected my plugs yesterday, and they were all white. Does the high compression of the M42 make it burn that hot, or am I really lean? I have a new FPR too.

          I wanna say you're running lean, look around for vacuum leaks maybe?

              I use the BMW recommended NGKs. No mods to ignition, just Ark D chip.
