Pulse Plugs are different than spark plugs

Pulse plugs are a radical departure from spark plugs. For 100 years, spark plugs have remained much the same as they are today (history of the spark plug) generating only 50 watts of peak discharge power.

Pulse plugs may look similar to spark plugs on the outside, but inside the technological advances of Pulstar are evident. Pulse plugs feature a unique capacitor-based circuit that captures energy normally wasted by spark plugs and generates a spark with 10 times greater energy than any spark plug.

"The Pulstar Plug has to be the best automotive invention since rubber tires." - J. Coon, 1995 Chevy Suburban
