Wow, never heard a good thing ever about NGK until I read this! We got them in 4 wheelers, dirt bikes, etc and always replace them with something else. They seem to foul easier than other brands.

In ag. tractors we always used AC's or Autolites.........Champions are junk

In cars/trucks its AC or Bosch.

I have AC's in my nova, with 11.5:1 comression, and even to 8,000rpm they work great. Never had a probleom with them fouling unless I flooded the crap out of the motor.

I can see that happening tho if you dont have a good ignition system with enough voltage.
