    2002 WRX Front O2 Sensor

    The check engine light went on, brought my rex to the dealer and turns out the front O2 sensor is shot.

    The dealer wanted $600 (CDN) to fix it with the greatest chunk of the price being the O2 sensor itself. I knew that was FAR higher than I should be paying so I took the car back before any work was done.

    I looked around online for an O2 sensor and the prices really differ. As low as $22 and as high as $150. What's the difference and is there a trusted brand amongst the gurus here?

    thanks!

    I bought mine from the dealer for about 200$US. Since you are in Canada I am going to guess that your o2 sensor will be very hard to remove. My o2 sensor is basically stuck on my old exhaust manifold elbow. I put my new one in a P&P'd exhaust manifold that I was installing. Good luck.

    Thanks for the responses so far.

    The main question I have is, was there a particular brand/part number that any of you used that worked well or will anything do in this case?
