champion plugs

If anybody MADE a plug for my mower besides champion I wouldn't run them there either. I had HORRIBLE luck with them in the 80's, basically the damn things had a tendancy to crack and fall apart, and didn't last long if they stayed in one piece. I've tried AC, NGK, Bosch, and keep coming back to the Autolites. They've worked well for me for years, and I'm about through experimenting. Even tried the splitfires when they were new, they didn't last 5000 miles in a V6. Opinions vary..
