I have a brand new in the box 02 sensor for a WRX. It is the one that goes in the exhaust manifold before the uppipe, I thought I needed one and then my friend who works at a dealership hooked me up with one, so I have no use for this. I paid $145 plus shipping, so if anyone wants it just make me an offer..

My WRX is an 03 but I am sure it fits all other years. I WILL CONSIDER TRADES FOR THIS PART TOO so let me know what you have that you dont want!
