More efficient combustion ,more fuel burnt equals more power
I found this article on a site ....We haven't seen any benefits of gaps beyond 0.045-inch, so that should be the outer limit of sparkplug gap. Don't re-gap sparkplugs too many times because the ground strap metal will fatigue and may break. If your engine makes more than 75 horsepower per cylinder, gap the plugs only once. If your engine makes more than 100 horsepower per cylinder and/or sees extended periods of high RPM and/or high boost, we'd have to say don't gap the sparkplugs at all! (Here, it pays to use high-quality plugs that have a consistent gap as-manufactured.)
