A center electrode extends through the central axial bore of the insulative sleeve. A metal sleeve is provided, wherein the insulating sleeve is positioned within, and secured to the metal shell. A ground electrode is coupled to the metal shell and positioned in a spaced relationship relative to the center electrode so as to define a spark gap.
