Thanks for that info. Will check. I did find one on RockAuto.com for $33.79.
Its a DENSO Universal OXYGEN SENSOR, Part # 2344209.

Dont get a universal O2 for a OBDII car. They dont last as long as the OEM replacement units. Also DENSO is OEM. DENSO makes half the parts on every Toyota and Lexus. Going with universal 02s is only a good choice if you have OBDI and a single wire 02. Bosch will work as well or NTK ( division of NGK ). But best bet is Denso for longest life and best performance.

Yeah i didn't go with the universal one. Occasionally people on CL will sell new O2 sensors. I was able to scoop one up from CL.

Thanks! You guys are the BEST! Saved me from making a bad purchase! I will NOT get the universal one than! I will buy strictly OEM.

OBDI should be a single wire. OBDII has a 4 wire as its a heated 02 sensor. Single wire sensors operate on a less complicated principle, only 1 wire vs. 4 wires, the 4 wire heated sensors have a heater circuit which helps to warm up the sensor to operating temperature so that it can read properly much faster. 02 sensors generate a voltage that the ECU translates into the air/fuel ratio which in term tells it how much fuel to inject, how much timing to run etc.

Using a universal 4 wire sensor also increases chances of mixing the wiring and causing all sorts of electrical issues. On a single wire 02, you cant mess it up since its just a single wire. Also application specific sensors tend to last longer and seem to be more precise in giving the ECU a proper reading AKA car will run better / smoother. I have used several universal single wire 02s on older Nissans and on my own SC300 and so far no problems. However serveral of the universal 4 wire sensors that I have dealt with gave me all sorts of issues both on start up and after a period of time. It all really depends on the vehicle, but certain cars tend to be picky with the parts that you put on them.
