10mm

If you have a socket set without a plug socket get a socket that suits your existing ratchet either 1/2"or 3/8"

If you are not intending to do lots of car mechanicing use one of these

and with rubber in or magnetic what do you use,

Most people use one with a rubber insert you can now get a magnetic socket. never used the magnetic one.

also is the gap pre set.

Never assume anything, get a set of feeler guages as well to check before you install the plug.
