Can I just change 1 o2 sensor?
Yes, you have to replace 2 Oxygen sensors if your car has one catalytic converter with one exhaust pipe. One sensor is in the front and another one is after the catalytic converter and remember don’t mix them up, the one for upstream before the catalytic converter is different from the one behind the converter.

How big is the O2 sensor socket Socket?
The “special” O2 sensor socket is a 7/8″ socket with a slit up the side. As far as I know they only come in one size. Warning!! Be sure the vehicle is totally cooled down before doing this. The exhaust manifold gets extremely hot and can severely burn you. Give the engine at least 2 hrs cool down time (time not running).
