Changing spark plugs on your Spec Miata or any vehicle can be a pain. The plug sticks to socket and stays in the plug well. Advanced Autosports has created “The Spark Plug Spinner” that makes changing plugs a breeze. This one piece design eliminates the need to find the plug socket, find the extension, find the ratchet. And you will never have to dig that socket out of the plug well. One tool is all you need. We have redesigned our spinner with a black oxide finish (same as your impact sockets) to prevent paint from chipping!
