ABSTRACT:
A spark plug for an internal combustion engine having one or more electrode diagonally projecting from a central electrode into a V-shaped grounding window which is cut into the skirt of the spark plug body. The novel electrode suspended in the grounding window provides broader spark dispersion, through a wider arching area, and greatly improved spark plug life.
