Are Down Pipe O2 Sensors The Same?
I'm running LS6 headers on my LS1. Iv'e found that the right side requires an O2 sensor with a slightly longer harness. One of the down pipe O2's does have a harness that's just the right length, so I'm wondering if I can simply use it in place? I thought I read somewhere before that they can be swapped without issue.

I bought a Bosch universal 4 wire O2 sensor because it came with a much longer cord. I think it was almost 3 ft but you have to cut the existing harness and use theirs. Their harness is pretty slick though. I've heard though (reading the "PCM Tuning section") that folks have had trouble with the Bosch in terms of lazy warm up which will throw a CEL. If you go this route the factory Pink, Brown, Black, White wire doesn't match up with their instructions. I can give you the wire diagram if needed. I just did this last night.
I'm only using the front 2 of the 4 and have not test driven the car yet so I have not verified those claims.
