Champion Truck Plug

[JEEPERCREEPER]

Someone have a number for the Champion "Truck" plugs some of you are running. Think I'm going to replace my Bosch's. '89 4.0.

I just look at an extra plug I had yesterday. I think it is 12RJC or something like that. It is the same plug that goes in my lawnmower but it is hotter than the mower's.
