This KWB spark plug socket stands out with its integrated rubber insert, which holds the spark plug securely during installation and removal, preventing drops and damage in tight engine bays. The 21 mm hex profile fits common spark plug sizes, and the 1/2" drive makes it compatible with standard ratchets, breaker bars, and torque wrenches.

Highlights

• 21 mm socket size for common spark plugs
• 1/2" square drive for use with standard tools
• Integrated rubber insert grips the spark plug firmly
• Knurled grip for better handling with oily fingers

In daily use

The rubber insert holds the spark plug securely, so you can guide it into the cylinder head without fear of cross-threading. The knurled grip gives you a solid hold even when your hands are greasy. The chrome finish wipes clean easily and resists corrosion in the workshop environment.
