Straight from the FAQ
6) Oxygen sensors. If an oxygen sensor is messed up, it will trigger a Check Engine Light. There are three sensors in total. 2 rest in the respective branches of the Y Pipe (these are the Front Heated 02 Sensors) and one rests in the catalytic converter (95-96) or in the B Pipe right behind the cat (97-99). If any of these sensors fail, gas mileage will decrease substantially. Many sites exist that sell oxygen sensors (dealers will charge a lot). www.buyoxygensensors.com gets good reviews on this site frequently, and they have good prices. For a writeup, go to www.motorvate.ca, or search around the .org

NTK (the oxygen sensor branch of NGK) makes OEM sensors. They are probably almost half the price of one from nissan. I would think the sensors would be perfectly fine seeing as how nissan says ONLY to use NGK plugs...

Cali or Fed spec? There's never two rear, always at least two front. Cali spec has 3 up front and no rear, Fed spec has 2 front and one rear.

I think the OEM sensors are made from Bosch, you don't really have to change the rear ones, just do the front sensors in the Y-Pipe.
