What is a “pulse plug” and how is it different than a regular spark plug?
After 15 years of extensive development and testing, Pulstar® pulse plugs contain an internal, very efficient and patented capacitor element that stores energy to discharge into the fuel charge once the spark gap is ionized http://en.wikipedia.org/wiki/Ionization. By definition in the Society of Automotive Engineers specifications for a spark plug, the Pulstar® pulse plug has more “capacitance” http://en.wikipedia.org/wiki/Capacitance than is allowed for a spark plug.
