I haven't found a buyer over at clubrsx so I'm trying here, I have a used secondary 02 sensor with 25,000 miles on it for sale. Taken off in perfect working condition. Make me an offer, they retail for about 300. Here is my thread over at clubrsx: http://forums.clubrsx.com/showthread.php?t=387027

I'm looking for around 100 shipped but make me an offer if that's too high
