I dig NGK plugs, bought one for my old go kart with a 6.5HP 212cc predator, but I don't remember the part number on it, gimme a bit I'll rummage through my files. I save everything, so I should still have all that.

Autolite 3910X is what the Kart guys use. This is what we run in our MiniPro machines.

NGK BPR4ES OR BPR2ES

why would you run a plug that hot. you want the right heat range for the engine and most of the time colder is better.

factory honda is ngk bpr5es or bpr6es
