Spark plug sockets are designed to fit over the plug with a rubber insert to prevent cracking, while wrenches often have open ends or fixed sizes. Sockets generally provide better grip and protection for the ceramic insulator.
Magnetic sockets are highly recommended as they hold the spark plug securely, preventing it from falling into the engine cylinder during installation. This feature significantly reduces the risk of costly engine damage.
Most motorcycles and small engines use 16mm (5/8 inch) or 21mm (13/8 inch) plugs. Always check your vehicle's manual or measure the existing plug's hex size before purchasing to ensure compatibility.
