May I know what's the Heat Range for the 32192-10 Screaming Eagle spark plugs? I just pulled them out from my 2012 FLHR and they doesn't look pretty. Will need to get some NGK replacements.
what are the actual numbers on the plug itself?
they are made by champion to hd tight spec's. champion uses a rising number system for heat ranges. if you want to change brands, cross the standard hd plug number to what ever brand you want. remember, plugs are riddled with all sorts of unfounded info. the screaming eagle just uses a better plating and exotic electrode and ground material that helps them fire in high performance engines. they are not any better in a stock engine.
