Easiest Way to Remove O2 Sensor - header swap

I can not see how to separate the wiring going into the sensor so that I can get a wrench over the sensor. Should I rent a "sensor wrench" that has a slit going up the side to clear the wires - then able to remove sensor from the header?

Sensor wrench

You could try an open end wrench?

unplug the o2 after the cat(plugs are on fire wall). remove the cat then pull o2's. unplug header o2 (plug on bottom of coil pack)then remove the header then pull the o2. you can get proper tool with slit at autozone for like 7 bucks....makes things much easier!!! if 02 turned the rt way you can get with box end wrench....but if you luck any like mine lol

They make a cheap socket that works great on the end of a rachet.

i couldn't get mine off, i let them sit in PB blaster for a day, got the o2 socket and even slight taps from a hammer would budge it,, i ended up rounding them both off and breaking the socket. good luck.
