Do yourself a favor and get the following:

- penetrating oil
- crows foot socket
- long extension for your ratchet wrench

I had to use the penetrating oil to get my 02 sensor to budge...and without
the crows foot socket, I wasn't able to get much leverage on the sensor.

I know I don't need to tell you this...but put the penetrating oil on when
the engine is cold.

Also, some say that it's easier to get the sensor out with the engine warm
(but not hot).

I'd consider these two recommendations as mutually exclusive :)

HTH,
