This may or may not be the right forum, but being that I spray the **** out of the car and figure you guys swap plugs a lot, too, someone might have an idea. I was pulling plugs today to check how they are looking and one of the plugs came out looking very odd. The electrode was a good tan color, the burn line was showing low timing, but I expected that being that I have been running on my nitrous tune full time. What was weird about it was the porcelyn was half tan and half white, divided right down the middle. If you are looking at the plug toward the square end of the ground strap, the right side of the porcelyn has color, the left side does not. Any idea what that is all about? The rest of the cylinders were the typical whitish tan color all the way around and looked similar to the plug everywhere but the white side.

The plugs were not indexed, and the ground strap blocked the whitish portion from the flame front. Thats my educated thinking on it.
