Wire ground electrode spark plug for super flow

A spark plug for an internal combustion engine comprising:

• a housing defining a central bore and a plurality of threads configured to engage a plurality of mating threads formed in the internal combustion engine to removably couple the housing to the internal combustion engine;
• an insulator received in the central bore;
• a center electrode received in the central bore and spaced apart from the housing by the insulator;
• and
• a ground electrode formed of a round wire having a first end, a second end, and a base portion, the first and second ends being welded to the housing for electrical and thermal conduction with the housing, the base portion being supported by the first and second ends apart from the center electrode to define a spark plug gap between the center electrode and the base portion;
• wherein the center electrode includes a center electrode tip and the ground electrode includes a ground electrode tip, the center electrode tip and the ground electrode tip are spaced apart to define the spark plug gap;
• and
• wherein the ground electrode tip is disposed on a flat surface that is formed in an interior side of the ground electrode by recessing the interior side at a position furthest from the housing.
