still no answer to the "stupid old man question of the day" about gapping the new type plugs and not screwing up the tiny tip elements ?
i try not to sound idiotic, but i try to learn new methods of doing things when possible.
All the racing plugs I use are V gap manufacture says use them out of the box. All the new style plugs With precious metal electrodes I use them also out of the box. A good racing ignition as well as newer OEM ignition systems will jump almost any gap. Gapping plugs is mainly for older style plugs in older style engines, so the old-style gapping tools still work. Back in the day we used to close gaps a little to make them run better. On new stuff it just doesn't matter. I taught at an automotive technical college we had two 350 horse SBC as mule motors. After a discussion in class, I had students index the plugs and change gaps we ran about 25 pulls that week, answer was indexing plugs and changing gaps made little to no difference.
