That sounds very interesting...I myself just watched the video comparison of the traditional plug and the Pulse plug, and how much faster the flame front moved. To me it makes sense to want that so that more gas could theoretically be burned in the same time period. More complete combustion and sooner=more burned fuel/less waste, etc. Burning faster also equals burning hotter, so more pressure, and consequently more power. The claim that the Iridiums are 99.999% efficient is a somewhat relative term. They may be very efficient from a conductive standpoint, but that doesn't necessarily make them ideal. What are the so efficient in doing? I find it absolutely naive to believe they can be so close to 100% efficient at burning all the gas off in every different type of cylinder/piston/valve system that they are used in-sorry,but I'm calling some heavy BS on that. Also, higher horsepower can lead to higher efficiency if other factors are right. The only concern I have about the spark kicking off the flame front so much faster is detonation. There's a reason gas is used in engines the way it is. So you get a "slow", even burn, not an sharp, severe explosion like in a gun. I think the jury is definitely still out on this.
