The correct spark plug gap does not depend on which plug you use, it is dependant on what engine it is installed in. The same plug can be used in many different engines, and each engine might have a different gap specification. Instead, you need to ask something like: What is the correct spark plug gap for a 1993 Chevy 350 engine? (or whatever engine you have).
