  • Motion Pro Spark Plug Socket

    Motion Pro Spark Plug Socket

    Tibbits in UT

    Well built but...

    It's a well built 18mm socket with several different ways of turning: wrench, socket, even has a hole if you need to break it loose with a screwdriver, (on tight applications where sockets won't fit.) But it does not fit into the small area on the XR400s, better to go with the Honda OEM thin walled socket.
