None of the "wonder plugs" gives you any more performance than a brand new regular type plug with the correct gap. Most of the multi-electrode or split electroide or grooved electrode plugs are better only in the sense that they extend the useful life of the plug a little.

Spark energy is best when both the center and ground electrodes have sharp edges. In time, these sharp edges get worn out and become rounded, and the spark energy or intensity decreases, which under some conditions could possibly decrease the max performance of the engine. In reality, the difference is barely noticeable.

I'm just old enough to have learned the trick of sharpening the electrodes on a worn out plug to give it another lease on life. These day, it's far simpler to swap brand new ones in.
