Hey Jeff. Actually thanks for that explanation, i'm always up to learning more. I just figured that if you mess with the heat range of the spark plug with a high voltage ignition (or even the stock one) and you gap the plugs farther for more spark travel, it increases the resistance and increases the operating heat of the plug very high. I also thought this would contribute to preignition and combustion chamber heat would go up enough to melt the plug. I had just "heard" that high voltage ignitions are more prone to melting plugs, but i've never personally experienced this myself, so what do i know. Just thought i'd let you know my train of thinking. If you have any other things you know, please share, the more i know, the faster my stang will go
