Abstract: A heat resistant spark plug extender is described, for joining a spark plug like ignition device to a spark plug wire. The extender includes an elongated body formed of heat resistant and electrically insulative material that extends between a spark plug engagement end and a spark plug wire connector end. A conductor is located within the body and includes a fitting, adapted to releasably electrically connect to a spark plug wire, and a receptacle, adapted for electrical connection to a spark plug. An adjustment part permits adjustable movement of the spark plug wire connector end relative to the conductive receptacle.
