I'm not sure any spark plug is made to withstand that much voltage going through it. The main reason spark plugs need to be replaced in the first place is from the wear of electric current. The gap increases because the electrodes wear away from the spark. Doubling the voltage through it doesn't equate to half the life. It could blow the electrode in half or break the insulation apart rather quickly, and could cause some broken pieces to be left floating around inside your engine. And the same goes for the plug wires and your cap/rotor. Assuming that it would work, I really don't think there would be a lot gained over just going with the MSD coil with larger, less resistive wires, and hotter plugs. The 2 plugs per cylinder idea helps a little since there are 2 seperate sparks in different locations in the cylinder. The idea is to speed up total combustion in the chamber.....it comes to a limiting factor of how quickly the eplosion....after the spark....travels throughout the cylinder. The spark is only meant to start this explosion.
