Evo 8 rear o2 sensor removal....HOW THE F***??
There may already be a thread on this but i only found the thread for an evo 9 removal. Hence the new thread.
So I've been wrenching on the rear o2 sensor for a few hours now intermittently soaking in liquid wrench and that blaster (pv pb?) and started to round off the bolt so I stopped, rented the actual o2 socket set from napa and am now waiting on the socket itself.
In the meantime any ideas on how to remove this POS?? The entire exhaust (turbo back) is on the ground attached only by the friggn rear o2 sensor so heating it up via natural exhaust is kind of the last thing i wanna do being that i'd have to reattach the damn thing. I'm tempted to just clip the wires and install a Bosch universal replacement (good idea? bad idea?)
I've heard heat, blaster and breaker bar are the best but i'm working with very limited room being that i have a POS jack that's too small. Haha i'm very poorly equipped for this job but i'm *******ed determined to get it done.
BTW i'm replacing the stock exhaust with a full turbo back invidia system with a test pipe/cat delete. Just in case anyone cares haha.
thanks in advanced!!

yea i think the bosch o2 sensor swap is kind of a last resort for me being that i'm not a wiring guy and have no experience doing so. I'll post updates when i get the o2 ratchet. thanks!

you could just clip the wires and not replace it. You would want to remove the harness from inside the car too though so you dont have the chance of shorting out the circuit.

I've never worked on a 08 o2 rear sensor before. Was it possible to get to while the exhaust was bolted up to the car? If so, there was your leverage. Anyway... heat it up, use the right socket and give it a couple smacks with a hammer (since you say limited space).

I ended up cutting the wires on mine too since I was working on it in my work parking lot (s*** happens at the best time). When I got it to the shop and they told me the replacement cost, I wished I had tried to wrench on it a little longer.
