Back in my drag racing days, I was a fan/user of Champion plugs, and they seemed to outlast most others in high compression engines. However, I noticed that the NGK plugs really did seem to work better/last longer in my motocross motorcycles. It seems like the quality of Champion plugs has declined over the years. Now I stick with NGK in most cases. Hey, we know they work, why mess around with other brands?
