Don't compare multi electrode plugs to the benifits of twin plugging. They have nothing in common. A twin plugged engine will have two sources of ignition and will generate two sparks. A multi-electrode plug will only generate one spark. The only benefit that I can see is that if one electrode gets fouled the spark will use a different route.

I used splitfire plugs for a couple of years. I didn't notice any difference in performance (other than the normal increase when putting in clean plugs), but the plugs ran fine and never fouled. I switched to NGK's, because they're cheaper.
