Re: L-78 Spark plug choice

I believe the Champions used to be preferred by racers because you could read the heat bluing color on the shinny threads. It's hard to get a true reading on the porcelain on a fresh set if the car is running good. (that's my feeling) but my racing buddy likes to put in a fresh set then pull them at the top end of the track before driving back to the pits. I guess I shouldn't argue with his wisdom.
