745677 1 2 Drive 21MM Spark Plug Socket

Designed for professional use, these Sonic Equipment spark plug sockets feature a 65mm length and a integrated rubber insert to hold the plug securely. The external hex drive is a critical feature for Harley-Davidson owners, allowing the use of a wrench in tight spots where a standard ratchet and socket combination will not fit. This prevents the need for excessive disassembly when performing routine spark plug changes. Sonic Equipment tools are known for their robust construction and thoughtful design, ensuring that these sockets provide a long-lasting and dependable solution for ignition system maintenance in any garage or professional workshop environment.
