Did what I was hoping for, check engine light turned off. Lubricate the threads of the old sensor with penetrating oil and let it soak overnight before attempting to remove it. I don't have an O2 sensor port so I just used a box wrench and it worked great for my car that wasn't in the salt. Original part from AC Delco. I've seen some people say that other brands can cause Check Engine Lights so I decided to pay a little more for AC Delco. The light is off, the car drives well, I'm happy.
