    Plug gap

    We run a max of .012 on any blown application. When testing there was a HUGE difference between .012 and .018. When under high pressure and .018 gap the spark would jump out the vent hole in the cap and down the mag base. Would not fail at .012. This solved the rod kicking in Nitro Coupe when the spark would jump to the next cylinder coming up to fire.
