Yeah, I would have to try that myself. I've always been a sceptic of noticable performance from a switch in spark plugs, unless it's a faulty plug(s). I have a real issue with the E3 spark plugs. The spark is going to take the path of least resistance, so there will only be one spark. Now maybe where different types of metals are used in the electrodes that can conduct electricity better, but can that actually be felt in the performance? Now a good coil or a system that enhances the spark, maybe.
