you're going to have to put in some real effort to use a 1/4" drive ratchet with a spark plug socket.
I was referring to the extension piece, not the rachet itself.I have a little 1/4" ratchet set that I use for the spark plugs. I doubt the handle is longer than 4.5" or so. Works just fine. Torque's only 14 ft-lbf, so any a ratchet of any length will do.
