I'd like to pick up NGK plugs for the Roe s/c Viper I worked on. I tossed the Bosch plug boxes that the plugs Roe sent me in, so I dont have a cross-reference to go by. Are they 2 ranges cooler than stock? Special boost/nitrous plug, etc.
NGK FZR6F11-That's close, but the order of the numbers may be switched around. I can't remember exactly from the top of my head. The part number is some culmination of those numbers and letters.
