Abstract: A dedicated tool for the sole pupose of servicing spark-plugs on internal combustion engines with exhaust headers or obstructions where a tradiional spark-plug socket fails to perform. A single body tool, designed in multiple lengths. Designed as a multi-piece tool system. Each tool body contains an internal hex to mate with the appropriate sized spark-plug. Opposite end contains an external hex to allow an open-end or closed-end wrench to be used to tighten or loosen the spark-plug requiring service. The length of the external hex is critical to the effectiveness of the socket. The long series sockets incorporate a ⅜″ square drive to allow the socket to be used as a traditional spark-plug socket. All sockets contain a vertical mill slot to shorten the effective length of each socket. The vertical mill slot is also extremely critical to the effectiveness of the tool system. The vertical mill slot will allow up to a 90 degree installation angle.
