It is a general with Magnet's Plug wrench.
I noticed after I bought it that it was a rare 12 square Type.
Naturally, you can also turn the regular hex Spark plug.
Plug wrench is necessary because Plug falls in a normal Deep socket.
This Wrench is thinner walled than a typical Socket, making it easier to work in tight Plug holes.
Looks like you access from European region.
