The Sealey AK6552 solves this with a 250mm long, 16mm, 3/8" square drive, 12-point spark plug socket built specifically for deep-seated applications. The magnetic insert retains the spark plug securely during removal and installation, preventing it from dropping into the engine bay. At 250mm in length, it provides the reach needed where conventional sockets simply cannot access. Backed by Sealey's lifetime guarantee.
