Liquid wrench (CT), spray it and wait for about 30 min. Then try to crack loose. If this doesn’t work, then get a propane torch and heat it up real good and again spray it with Liquid Wrench. Try to crack loose imediately after this heating/quench.

I hope it comes out for you. Good luck.

Finally got it off, Tried heat, didn’t work, Used alot of penetrating oil and a 22mm socket, the O2 Socket from Napa didn’t work, it stripped the sensor for me…

Penetrating Oil + 22 mm Socket = WORKSS
