BILITOOLS Magnetic Spark Plug Socket Set 10-Piece with 3/8" Torque Wrench, 10" Extension & Gap Gauge

The BILITOOLS 10-piece magnetic spark plug socket set combines a click-style torque wrench, magnetic plug sockets, a 10" extension and a gap gauge to help you install spark plugs accurately and safely.

If you work on cars, motorcycles, lawn equipment or small engines, consistent spark plug torque and secure socket retention matter. This kit pairs a 72-tooth, click-type torque wrench calibrated from 10 to 45 ft-lbs (13.5–61 Nm) with a full range of magnetic spark plug sockets and a long reach extension so you can reach recessed plugs without dropping or over-tightening them. The included gap tool helps you measure and set electrode spacing to manufacturer specs.

How does this set prevent over-tightening spark plugs?

The torque wrench features a 72-tooth ratchet and a click mechanism that signals when you reach the preset torque, helping avoid over-torque damage. Its fine 5-degree swing arc gives precise adjustments in tight engine bays, and the calibration range covers most common spark plug settings for cars and small engines.

• Click torque range: 10–45 ft-lbs (13.5–61 Nm) for controlled tightening.
• 72-tooth ratchet: requires only a 5° swing for incremental torque control.
• Audible click when torque is reached to stop tightening.
• 3/8" drive compatibility for common sockets and extensions.

What sizes and features do the magnetic spark plug sockets have?

The set includes seven magnetic sockets in both metric and SAE sizes to match a broad variety of spark plugs. Each socket has magnetic retention to hold the plug securely during insertion or removal, reducing the chance of dropping a fragile plug into the cylinder.

• Metric and SAE sizes: 14mm, 16mm, 18mm, 9/16", 5/8", 3/4", 13/16" to fit most plugs.
• Magnetic interior retains plug for safer handling and easier access.
• Durable construction intended for repeated garage or shop use.

How does the 10" extension and gap tool improve spark plug service?

The 10-inch, 3/8" drive extension reaches deep-set plugs found in modern engines, letting you work without awkward angles or stripped threads. The included gap gauge offers both SAE and metric thickness blades so you can measure and adjust electrode spacing to OEM recommendations.

• 10" deep-reach extension for recessed spark plug wells and hard-to-reach cylinders.
• Spark plug gap tool with SAE and metric markings for precise gap measurement.
• Combination lets you remove, check, gap and torque plugs with one kit.

Will this set work for both cars and small engines?

This kit covers the most common plug sizes and torque needs across automobiles, motorcycles, ATVs and many small engines. While it suits a wide range of vehicles, always check your engine’s specific socket size and torque spec before use to ensure compatibility.

• Useful for passenger vehicles, light trucks, motorcycles and small engines.
• Torque range fits typical spark plug manufacturer recommendations.
• Verify vehicle-specific socket size and torque spec before beginning work.
