Cheaest o2 Sensor
So one of the oxygen sensors went out after my last trip to the dragway. Threw in the cheapest race fuel. Obviously that didn't work out. Is there a universal sensor that can be used? Autozone has one for $70 dollars. I'm finding OE sensor for $140. Need to save some money on this one if possible...

Thanks you guys. I ended up getting the universal one at Autozone. It comes with a high quality wiring harness adapter. It's bank 2 sensor 1. Which is that? I'm going to assume it's the pre-secondary cat sensor? I've been driving her for over a week with the CEL on. Might have damaged secondary cat? How does our engine handle a bad o2 sensor?

Could someone clarify if Bank 2 Sensor 1 is passenger side. Bank 1 would be on side of cylinder one which is driver side(?), so bank two is passenger side and sensor 1 is the first sensor before primary cat? Thanks...

Well then, thanks for the help, LOL... Cylinder 1 is on the passenger side. Bank 2 is driver side. Replaced sensor wasn't too much a PIA. Really no room to work with. I ended up using an o2 sensor removal socket. Had to place it on and hit the edge with a breaker bar to loosen the old sensor. The wiring harness adapter worked really well, and CEL is gone. The old sensor looked really worn. Should I consider replacing primary passenger side sensor even though it hasn't triggered a CEL?

Hey I have to replace my upstream right 02 sensor but do not know the location. Do you have pics? What size 02 socket? The dealer quoted me $500 for this job. If you could provide some help I'd try to tackle it myself! Thanks so much!
