use a dealer o2 sensor. it has the correct calibration for your car.

how this o2 sensor job is done?
TIA, ColtX

ColtX:

The OS sensor on this car is easy but most of the time you will find that it is ceased into the housing after you have a replacement O2 sensor this is the easiet way look at your exhasut manifold on the front of the engine look for the think that looks sort of like a spark plug cut the wires running from it put a deep socket of the proper size on the OS sensor (after a liberal spraying of WD-40, Slick 50 or your favourite lubricant) then get your biggest johnson bar and your favourite cheater pipe and crank on it now be prepared this thing might come out easy (probably not) it may end up taking the threads out with it and you'll have to retap the hole. Now you could use this as an excuse to buy a nice new performance exhaust manifold.

Hope this helps...

Thanks Berserko for this, the gasket, and cat advices. They really help me a lot. Now, I just need to gather all these pieces and hit the dust. Btw, I took a look at the mainfold exhaust and O2 sensor, and yes, I'm better off buying a nice new performance one.
Thanks again.

ColtX: no problem if you get that manifold let me know how it goes because I may end up getting it until the GF will let me put in a 4g63t
