Abstract: The invention is a spark plug having a novel cap attached to an end of the spark plug's central electrode, as well as a cylindrical extension attached to the outer shell of the spark plug. The cap is generally concave and star-shaped, with a plurality of projections protruding from the periphery of the cap, wherein the cap includes a thick central dome, and thins out in a radial direction towards the protruding projections. The cap, the central electrode, and the cylindrical extension are all made of a novel alloy which, in conjunction with their novel structure, allow for the simultaneous generation of a spark from every single projection on the cap. Such simultaneous, multi-spark generation provides a more rapid and complete combustion of the air-fuel mixture within the cylinder of an engine, which, in turn, results in increased torque as well as reduced emissions from the engine.
