I know the spark will jump the shortest path, but how is that to your advantage?
It would be the same as gapping your single-electrode slightly less. As I said it can increase life by having the spark switch which electrode it usually jumps to as they wear down, but the gain wouldn't tend to offset initial cost. IMO those types of plugs are gimmicks... am I in for some highly technical explanation as to why I'm wrong?
I completely agree. gimmicks IMO too.
