I used a torch and open end socket (22mm I think).  I have seen O2 sensor
sockets in the auto parts store.  It looks pretty slick, with a slot for
the wire and everything.

When I bought my van, someone had actually tack welded the o2 sensor to
the exhaust pipe.  I assume that they also put anti seize on the threads
because I was easily able to break the tack weld and take off the o2
sensor.

But, I forgot to put antiseize on and it was miserable getting it off.  I
finally used a torch and the correct size open end wrench.  I haven't
forget to put anti seize on since.  And I suppose I should remind people
that you have to be careful to not get any antiseize on the sensor of the
o2 sensor, I have heard it will foul it up.
