changing oxygen sensor

[1scoot]

Has anyone here replaced their oxygen sensor on a 325i? I tried to get to mine and I couldn't even get a wrench between the exhaust and the floor. Is there a special tool to remove it? If not, what size wrench is it? Maybe I can modify a wrench to fit.
Thanks

From Bavauto.com:

"Makes removal of the old sensor and installation of the new sensor a snap. Turns easily using a 3/8 in square-drive ratchet or socket extension. The slotted design is made to fit over the sensor wire. For use on all Bosch brand oxygen sensors."
