Plug gap
Unfortunately, when people think of bigger plug gap benefits, they only think of peak hp. Not that it might give you a smoother idle or more miles per gallon. A smoother idle would mean the misfire is not as bad....& the hp went up. When GM developed HEI with up to 0.080" plug gaps, it wasn't because they had cash left over from the year before.....to splash.
