Pulstar Spark Plugs.....Gimmick or legit?

First, it is a known fact that exotic metals such as iridium and platinum do not conduct electricity as well as copper. All the iridium plugs do is allow a fine wire electrode that helps with reducing the voltage needed to jump the gap. Platinum is mainly for longevity.

Secondly, I dont consider it a waste to put in lower resistance wires. Have you ever measured the resistance of the OEM wires? Have you then measured the resistance of aftermarket wires, particularly MSD wires? Then have you done the math to see how much voltage is lost in OEM wires? I have and its considerable. Do you also know whether or not you would exceed the current limiting of the ICM with lower resistance wires?

You're expecting horsepower gains from plugs and wires. And while it does do that, its not significant and usually is better taken advantage of with timing adjustments. But the big thing is ignition system efficiency. Getting more of the power of the coils actually to the plugs. That can help with fuel economy among other things.

Additionally, while I do not buy into the Pulstar plugs, plasma ignitions are not all that new. So the concept of the Pulstars are sound, but the numbers and such they use is just not possible in our ignition set up and system voltage.

that looks like a coil inside the plug...a coil is called an inductor and with the right amout of turns and thickness there is a wide range of voltages that can be achieved but as far a 1 million volts go...a stretch at best but i do believe that there can be an enormous amout of energy produced w an inductor
