I am in need of an old lower o2 sensor. Maybe someone took theirs out when they did a turbo back exhaust. Thanks Derek
lower o2 sensor? Do you mean the front one by the manifold or the rear one in the 3rd cat. I have an extra front one for a WRX.
I'm looking for the one behind the cat. I'm kinda curious what the difference would be? If it's length. That's fine. As long as the harness is the same. Thanks bud. Derek
