There are several places to buy O2 sensors. The best place to go is to the dealer where you bought your vehicle. They will tell you the price range and then you can try to beat that price.
In my experience, OEM sensors work better than aftermarket.
All O2 sensors are threaded into the exhaust system at various points. Upstream O2 sensors are located before the catalytic converter(s) and downstream O2 sensors are located after the catalytic converter(s).
There are four o2 sensors on a montero sport.
There are total 4 O2 sensors. You can buy all 4 from Oxygen Geek and will cost about $260.
The 2.5 has 2 O2 sensors (both on top of the engine) and the 3.5 has 4 O2 sensors (two on top, and two under the car).
The o2 sensors screw in. There is a special socket for removing the 02 sensors with a slot in the side to clear the wiring.
All the O2 sensors are threaded into the exhaust system at various points.
The O2 sensors are located between the exhaust manifolds and the cat converter. They screw in to the head pipes. Those are also called upstream O2 sensors and in some vehicles they are also called air/fuel sensors. There are also downstream O2 sensors that are located after the catalytic converter.

All O2 sensors are threaded into the exhaust system at various points.
The 1992 Ford Taurus has two oxygen (O2) sensors. Both O2 sensors are located upstream of the catalytic converter with one on each exhaust bank.
