I just put NGK TR6s in the Cobra since I am running a small shot of nitrous. I put the plugs in, then 2 days later pulled them to change the gap from .040 to .036, since i was getting a little miss. The plugs were chalk white!!?? Usually this indicates a lean condition, however last time my car was dynoed, I was at 11.1 right accross the board. I know the chip is working since my shift light doesn't come on, and she is still running very hard. Needless to say, I haven't hit nitrous since changing plugs. The plugs I had in there before, Denso Iridium IT22s, were a nice brown color, perfect, so why are these NGK TR6s turning white? The only explanation I can come up with is the toulene that I am running to boost the octane rating. Would this turn my plugs white?
More info on toulene http://www.jwsvws.com/rocket_fuel.htm
Does anyone else run this stuff? I feel a great difference, and it runs cleaner with the toulene, I'm just wondering if the metal in the plugs doesnt like it...
