From what I've read. The higher the pressure, the smaller the gap. If your N/A open them up to get the biggest spark. If your boosted or running some sort of high comp engine or nitrous you need a smaller gap so the spark can make it across.

I personally opened all mine up (can't remember the exact #) made sure they were all the same. And I also got a index washer kit so that they were all pointing towards the intake side.

I can't really say there's more power but the engine sounds smoother to me.
