The invention is to a system in which a high voltage source is connected to and continuously supplies a RF voltage to each spark plug wire in an automotive ignition. The high voltage is capacitively connected by placing a metal clip on each spark plug wire and connecting the high voltage source to the metal clips. The metal clip and conductor in the spark plug wire forms the two plates for the capacitor and the insulating material on the spark plug wire is the dielectric of the capacitor. The application of the high voltage to the spark plug wire produces a continuous corona discharge at the tip of the spark plug internal to the engine. A corona discharge surface may also be on one surface of the engine head in the combustion chamber.
