Ever wondered what heat range plug you should use in your car, or what the heat ranges mean? I found the following a while back and thought that others might be interested in this info.
Great explanation and pictures to aid in spark plug diagnosis:

I am running two heat ranges colder with my setup and can verify that I have a light ash coloring after 1,500 - 2,000 miles which is dead on perfect gapped at "out of the box" .045 (lower than stock, but remember, I have a S/C).
