The spark gap called for in factory specs is .035. This will vary from engine to engine, and plug type, to improve performance and plug wear you can toy with it a bit. Do the fatory setting and drive abour 1000 miles, then pull the plugs and checj for burning, deposits, etc. To increase the spark set the gap wider, if the plug is too hot narrow the gap both starting from the factory setting.
Platinum plugs are set between .056-.052 . Mine runs perfect @ .054
