Abstract
The spark plug body includes radially extending stops which limit the movement of the spark plug body in one direction with respect to an aperture through a around plane surface. The spark plug body further includes bosses radially extending from a section of reduced diameter wherein slots are formed between the radially extending bosses and a ring-shaped transverses floor which is positioned to be coplanar with the ground plane surface. The prongs of a ground fastener extend though the slots thereby securing the spark plug body with respect to the ground plane surface. Additionally, the ground fastener includes a spark gap portion which is positioned with respect to the tip of the spark plug thereby precisely forming a gap and forming the electrical connection between the spark gap and the ground plane surface.
