Br9 or br8

Any of you guys run b9 plugs instead of b8s?

@declan Always ran a BR9ES, Seems just right with a standard engine

@Darty thanks!

I run a BR9EIX

@Mightyman same here. The number states the temperature "level" of the plug. The colder - higher number. Im heard the colder spark is better ...
