The are 2 types and different heat ranges. Regular and turbo plugs seal differently and aren't interchangeable.
Most of the time a No 8 or equivalent it the right answer. These are OS plugs. Most brands indicate which plug they are equivalent to on this chart.

I have used 20% and 30% nitro with a #8

Usually a medium plug works. It depends on the outside temp humidity and altitude. The fuel % doesn't dictate what plugs you run. Also want to run a good fuel. What 20% fuel are you running. Are you haven troubles tunning the engine? Are you failing plugs alot?
