Re: Which Spark Plugs?

Auxiliary gap or resistance gap means there is a gap in the electrode between the tip and the plug wire. This acts as a spark intensifier like the ones they used to sell at the county fair. Helps prevent fouling and gives a hotter spark especially if the gap is a little wide or the ignition not too hot.
