Probably going to get as many opinions on this as there are plug brands.... In the drag cars, we run NGK, on the steet, we run Autolites... But the lawn mower and snowblower still run best on Champions!!!!

Actually Champions run best in my 68 Chevy 350. Short reach plugs (3/8") that acually come in single packs. Last time I bought some the guy at the auto parts store asked me if they were for my lawn mower.

I have not tried AC Delco's (use them in my 57 Olds) but I have use Denso's and Autolites, but like neither as much as the Champion's.
