Its a socket with a slot in the side for the sensor wire.
You shouldnt need it.
You can get right in there with regular wrench.
Its the same as turning a bolt.

I found the cheapest price for mine, 4.0L sensors, at NAPA. I also checked Autozone and dealer. My engine requires 4 sensors. Price between $28 and $35.

If you don't have time to do it right the first time, how do you have time to do it over.

Unplug the wire, screw out the old one, screw in the new one, plug in the wire and your done.

Sometimes there is not much room to swing the wrench, so choose an Open-end wrench if available rather than an adjustable one. I cut the wires off and used the appropriate Deep-well socket.

Best price I found on 02 sensors for a 4.7 was actually at the dealer. 
Autozone wanted $130/each.
I don't remember what Napa's price was.
The dealer was around $80.

If you need to use the box-end of a wrench, the connector wont fit through, so its another case of cut the wires,then get the wrench on it. But yeah, the tool is not really needed. I have one and never use it.

A little anti-seize on the threads is a good idea too.

I got my 02 sensor for something like 49 dollars from ngk, in terms of removal I got angry and beat it off. then a simple socket. To reinstall I got 1 of those extra sockets (not sure of size, I think 9/16's) and screwed the new 1 in.
