Like the title says, I have a spare front o2 sensor and knock sensor out of an '04 WRX. They are both in working condition and were pulled while I was trying to troubleshoot a low IAM issue from my datalogs (it turned out to be a torn inlet hose, fyi). The knock sensor would be a great addition for you geeks that want to setup a detcan or a knocklite. :biggrin: front o2 sensor = $100 knock sensor = $50 I'll get the part numbers a bit later if I decide to get off my lazy butt and go to the garage.
Ok, I finally got off my butt and went to the garage to get the boxes with the part numbers on them. front o2 sensor part # 22641AA042 knock sensor part # 22060AA100
