Engine horsepower is created from ignition velocity

Ignition velocity refers to the growth of the combustion flame front, the speed of which determines the amount of energy released from the fuel. The greater the amount of ignition energy the larger the spark. The larger the spark the more efficiently your engine can operate to produce horsepower or, inversely, better fuel economy.

Tests at an independent laboratory demonstrate how Pulstar™ pulse plugs burn fuel more efficiently than spark plugs, increasing fuel efficiency.

In this high-speed video (shot at 68,000 frames per second), you can actually see, in real time, the ignition plume of Pulstar™pulse plug growing at more than twice the speed of the iridium spark plug.
