You can cheat and make some race plugs out of standard plugs simply file or cut the ground strap off half way across the center electrode and set your gap this really works great !!


But most trick plugs don't help much ,,just try and experement
cut the ground strap all they way off and the motor will usually run and not miss or anything even without a strap at all The trick above is all I found on the dyno that helps
