Return PolicyProjected tip for gasoline. For Brodix and other aftermarket aluminum heads. For most magneto fired ignitions. Sprints and Late Models. 14mm plug, .750" reach, 5/8" hex.
Plug gap will depend on output of distributor and fuel being used. Most applications using methanol will be at .022" - .025". If your ignition sytem is a higher output, maybe able to go as wide as .030". Gas application should be .030" - .035". You should also consult manufacturer of distributor for their recommendations.
