I would say the factory plugs are ultimately the best way to go unless you have a lot of modifications such as forced induction. In that case, the guys that actually have forced induction would be a better source than myself.

You can never go wrong with ngk. I'm running a 7. They work great in 14:1 motors turning 14k rpm so they handle these tractor just fine.

Yeah, he was running those diamond plugs and the cage around the anod broke and tore up his piston and cly wall. I'm going to change mine out for NGK Iriiduims. Got all 10 for 30 bucks.
