745674 3 8 Drive 18MM Spark Plug Socket

Sonic Equipment spark plug sockets are engineered for precision and ease of use during routine ignition system maintenance. Each socket measures 65mm in length and incorporates an internal rubber insert to securely hold the spark plug, preventing damage or accidental drops. A key feature is the external hex drive, which allows the socket to be turned with a wrench when vertical clearance is too tight for a standard ratchet and extension. This is particularly useful for reaching plugs tucked under fuel tanks or behind frame components. These sockets provide a reliable, professional-grade interface for removing and installing spark plugs on various Harley-Davidson engine configurations.
