I use the Autolite # 3934 race plugs in my 15.0 tp 1 compression bracket motor that I race on E85, E85 doesn't like the colder plugs like the 3933 or 3932 shruggy
How much compression and type of fuel and octane are you trying to fire safely work

The car is mostly street driven at this point and is a 11:1 compression pump gas engine.
