Surrounding the center electrode is a fire hole which includes an enlarged annular space to achieve an increased volume of the fire hole to maximize the ignition of the fuel/air mixture within the fire hole. The ground ring may include a series of ports to facilitate dispersement from the spark plug of the ignited fuel/air mixture within the fire hole.
