I'm goign to stock up on some plugs and was wondering about what some of you were using, especially heat-range-wise. I'm using a factory GM plug for auto applications. The heat range is probably more than too hot for the application and running a cooler plug might help fight off detonation (I'm still tuning and would like to run a tad more timing if I can squeeze it out safely).
Thanks!
Thanks!
