Abstract
An extender for connecting a high voltage source to a spark plug has a conductive rod with one end suitable for electrical connection to the high voltage source and a second end suitable for electrical connection to the spark plug, and a sleeve injection-molded over the conductive rod so as to be in void-free relation with an exterior surface of the conductive rod. The conductive rod has a first end extending outwardly therefrom. The sleeve defines a spark plug-receiving receptacle at the second end of the conductive rod. An O-ring is received in a notch formed adjacent to the first end of the conductive rod. An O-ring is received in a notch formed around the inner wall of the receptacle. A spring is affixed to the second end of the conductive rod.
