I can't imagine that it's too hard to DIY this change... any tips? The stealership wants crazy money for the part, and I know I can fairly easily get to it myself...

TIA =)

 

its some what easy,just spray some liquid wrench or wd-40 let it sit for like 10 mins or so get a i think 22mm wrench unplug the sensor first take the wrench if you dont have the 02 sensor tool and just put it on there tap it with a hammer and it should come off but make sure you have lots of room to work with,i know you have a xb butr i have a tc and i just sprayed some wd-40 unplugged the sensor used a wrench and a hammer very carefully dont stripped it and it came off
