I still don't get you guys with that high voltage stuff. Tha max-voltage on the plugs depends of the gap (and the mixture). As soon as the current is flowing the voltage breaks down. If you wanna use the higher voltage you have to widen the gap and replace the wires. But will there be a difference ? I really doubt. Stay away from that cheap crap stuff, stay with BOSCH and the car will run.
My 2 cents, and my book about car electrics and stuff proves me right....
