Apply liberally with liquid wrench, allow to penetrate overnight, get big on it with a breaker bar and O2 socket. Easy.

Good luck getting them loose OP. I tried changing the sensors for Bank 2 and got really frustrated and eventually gave up. I saturated the sensor with PB Blaster and still could not get it to break loose. I was trying to get my hands on a blowtorch to help loosen them but couldn't get one. I just don't have the spare time now so I'm letting my mechanic change them for me. This is how my o2 sensor removal tool looks like:

Yeah I know exactly what u mean Im surprised I still have a car I was so mad I couldn't get the o2 sensor out I had to walk away from it and I have both tools you posted up but I never tried the breaker bar I wonder if would work?

Let the car run until hot then stop the engine. Let it cool down a little until the heat is manageable. The heat will soften the metal. Trust me, i could not get any of it out at all until i tried this method. You will have to feal with the heat under the car, but it will come loose much much easier. Good luck

Why do Gs3' constantly have problems with O2 sensors?

The above wont work. There's not enough space between the socket and firewall to get that on.
I did my friends Bank 2 Sensor 1 in March, we used this tool from autozone (along with the pipe from my jack as a breaker bar) We did use some PB blaster as well.

They are corroded on, so make sure whatever tool you're using is sitting flush. If not, you're just asking to strip it

That's what I do....and open ended wrench does the trick.
