Performance auto parts have found Pulsed Power Technology (PPT)

Pulsed Power Technology is the science of storing power for a relatively long period of time and then discharging the stored power in an instantaneous pulse of energy. Installing Pulsed Power Technology in a performance auto part increases horsepower while at the same time increasing gas mileage! That's right - you no longer have to give up gas mileage to increase the power and productivity of your car or truck!

A simple way to think about the Pulsed Power Technology behind pulse plugs is that it is similar to a camera flash, whereas spark plug technology is more like a flashlight. A camera flash is exponentially brighter than a flashlight even though they both may use the same battery.

The spark comparison on this page demonstrates the size brightness of a spark plug vs. a pulse plug.  Here it is easy to see how much more energy is accumulated and dispersed to be used by your engine.
