HKS Premium Tool Plug Wrench Set - Subaru FA20 / FA24 Engines

Developed with Japanese tool maker TONE, this four piece set is shaped around the tight plug wells of the FA20 and FA24 boxer engines, so plugs can be changed without the engine mount and crossmember work the factory service manual calls for and without any special service tools. It holds one plug socket plus three extension bars, two at 32mm and one at 50mm, all on a 9.5mm (3/8 inch) drive. The back of the socket is machined as a 17mm hex so a ring spanner or a socket can turn it where a ratchet will not reach, and the detent balls in the extension bars are deliberately light so the stack separates easily inside a crowded engine bay.
