Pulstar is a name not many people will be familiar with, but their full line of pulse spark plugs is ever growing. They currently offer a spark plug for virtually every late-model musclecar out there, and they even carry a line of spark plugs for trucks and motorcycles.

Enerpulse's Pulstar pulse plugs have been given the Frost & Sullivan Customer Value Enhancement award. That's a fancy way of saying their pulse plugs really do deliver better fuel economy and performance at a competitive price.
