i was just pondering if you use an aftermarket ignition system such ac MSD or ICE and use iranium spark plug with bigger spark plug gap, would that increase hp and bang!?

It will increase the spark power and the size of the spark if you gap it more, but with gapping it more the more chance of the spark getting blown out. So Gap it only a very little more as your not going to notice any HP gains from Ignition unless your turboed.
