I don't think so.... Not sure where you came to that conclusion but I don't think heat has much effect on the plug wires or reducing the "power" of the spark. Never heard of anything like heat interrupting electricity before. Although heat does increase the resistance of a conductor slightly. I doubt it would have much or any effect with pinging either. Don't think it would have much effect on preignition either. Or, atleast I don't see how it would. Ken
