Is there a similar benefit for multi-electrodes as for twin-plugging? Can compression be increased or timing changed? I realize that there will not be as much of a benefit as far as firing the 2 haves of the combustion chamber equally because the electrodes are all in 1 place. The flame front should be shaped differently than a single electrode, though. The single electrode covers the ignition point on top of the plug but the multi-electrode models allow flame travel directly above the plug.

Anyone have experience with these multi-electrode spark plugs?
There is a current spark plug thread that this would work better in??
