With the Facom B.J18A1 spark plug socket, you remove and install 18 mm spark plugs with complete control and precision. Thanks to its 90 mm overall length, you easily reach recessed spark plugs in deep cylinder heads without damaging the porcelain or hex. The standard 3/8" internal square drive fits securely onto your existing ratchet or torque wrench, ensuring smooth and direct torque transfer. Designed as a rigid socket without a universal joint, it provides the steady grip and reliability needed for maintaining cars, motorcycles, and garden machinery in any workshop.
