Spark Plug Socket Tool, Special Small Diameter

Some (most?) of the “earlier” spark plugs, and some of the “not specifically for Mazda Rotary” racing plugs have a short body, as can be seen in the pictures. With the eyebrow on the rotor housings around the spark plug holes, from 1981 on, normal spark plug sockets are prevented from gripping the spark plug.

The “eyebrow”  blocking the spark can be seen in the picture.

This socket is specifically made with a smaller diameter on the end so it can get between the spark plug and the housing.

The tool is fairly thin there so be careful with it — SPARK PLUGS ONLY!
There is NO warranty and no returns on this — We know what will happen – the same thing that happened around here way too many times. We go to use it, it is broken, and NOBODY touched it. The problem is it is the same size (13/16, 21mm) as lug nuts. Somebody tried to take a wheel off!!
Best advice is lock it up after YOU use it!!
