Would anybody have a sparkplug equivalent chart that could identify plugs interchangeable with Champion RC12Ecc, but a few steps colder?
I know about the unobtainable RC10Ecc that used to be made for inboard boat engines, but would like to go a step colder. Plug should have same installed height to fit under coil rail.
Thanks Guys, Bill
