## Long description

Proline Gala 21 mm spark plug key (model 9017852) is a purpose-built 21 mm socket for removing and installing spark plugs. Made from high-quality chrome-vanadium steel, the socket includes a rubber insert that secures the spark plug during handling and helps protect the ceramic insulator from damage. The compact design fits standard spark plug sizes and is intended for automotive maintenance and small engine repair; use with a compatible ratchet or extension for access in confined engine bays.
Advantages
The chrome-vanadium construction provides durability and corrosion resistance, while the PRO-DRIVE specially profiled edges distribute load to reduce point stresses on the plug head. The rubber insert prevents the spark plug from falling out and cushions the ceramic holder, reducing the risk of breakage. Compact 21 mm size ensures compatibility with common spark plug types and allows work in tight spaces when combined with extensions or flexible drive tools.
Suitable for (tasks / use cases)
Removing and installing 21 mm spark plugs in cars and motorcycles
Maintenance of small engines (lawnmowers, generators, scooters)
Automotive service and repair workshops
DIY vehicle maintenance by hobbyists and home mechanics

How to use
Select a compatible ratchet or extension and attach it to the 21 mm spark plug socket. Fit the socket over the spark plug so that the rubber insert grips the ceramic insulator. Turn the ratchet counterclockwise to loosen and remove the plug, or clockwise to install and torque to the manufacturer’s specification. For confined engine bays, use appropriate extensions or universal joints to reach recessed plugs and avoid excessive force on the ceramic.
Usage recommendations
Inspect the rubber insert before each use and replace the socket if the insert is damaged. Always follow vehicle manufacturer torque specifications when installing spark plugs and avoid twisting the ceramic insulator to prevent cracks.
