Does anyone know if they Beru Silverstone plugs are quality plugs for a 930? I know they are a good plug for a 951, but I didn't know if there was a difference enough in the 930 engine to require a different type of plug.

I suspect, due to the air cooling in the 930 engine, you would want a colder plug than what is typically used in a 951.

You would just have to get the appropriate plugs for the 930.

Personally I don't think it makes much of a difference as to what spark plugs you put in there, just so long as you have them properly gapped, with the right heat index.
