same heat range,same gap, same resistance, but the 4996 has a 8mm center electrode for longer life, where the ground electrode of the 5464 is tapered for "faster starts and better acceleration". !!?? I blew up the pic and the ground is tapered,sure as heck. So if I take a dremel to the ground on the 4996 do I get a faster,longer life plug?
