Anyone know where I can find a cross reference for Autolite to Champion spark plugs?
Just curious, as my motor used to run Champion rn12yc's back in the day, but the builder put in Autolite 66 plugs, guessing these are a bit hotter, because of higher compression and bigger cam. Just want to make sure these are good to go, I don't know autolite too well, but have read these are better then champions these days.
