spark plug comparison chartPosted by Oldster on June 14, 2002 at 13:09:36 from (207.1.25.114):
Does anyone know if there is a chart that gives the comparative heat ranges for most (if not all) brands of spark plugs? I have a 74 Ford p/up which has a cylinder that is fouling out the plug in it and need to get a HOT plug for that cylinder. I don't use the truck enough to make an engine rebuild worth while. Any information and help will be greatly appreciated. Phil
