For optimal performance, use the Ignitor with Flame-Thrower 40,000 volt coils. Delivers twice the voltage to the spark plugs, increasing horsepower, fuel economy, and spark plug life. 2:1 improvement over points in current fall time for increased coil output. Rotating cobalt magnets trigger a Hall Effect integrated circuit. Epoxy molding makes the Pertronix module impervious to dirt, oil, grease and moisture.
Will trigger most CD ignitions.
