Abstract
A spark plug includes a body and a center electrode. The body includes a first end, a second end, an insulating portion and a shell portion. The shell portion includes an exterior threaded section, a nut section below the threaded section, an electrically conductive, axially elongated firing ring above the threaded section and terminating at an upper surface. The center electrode extends through the body and includes a terminal end and a firing end. The firing end extends beyond the second end of the body and includes a plurality of tines. Each tine includes a first section and a second section. The first section extends radially from the firing end. The second section extends axially toward the upper surface of the firing ring and terminates at a tip. The insulating portion electrically isolates the shell portion from the center electrode.
