With the Facom B.S16A2 spark plug socket, you can replace deep-seated 16 mm spark plugs quickly and accurately. Thanks to its 250 mm length, you easily access deep, straight spark plug wells without stacking extra extensions. The integrated plug retainer holds the spark plug firmly, preventing it from dropping into the engine bay during removal or installation. Its rigid design without a universal joint delivers a direct and stable transfer of torque. Featuring a standard 1/2" square drive, this socket connects seamlessly to your ratchet or torque wrench for dependable engine servicing.
