I have an 2007 Audi A4 quattro and I need a before catalytic converter o2 sensor. Do you sell one?Vic J.Aug 19, 2022
Best Answer:Hi Vic, I'm happy to be able to assist you. This oxygen sensor is suitable for the 2007 Audi A4 Quattro and is for the upstream (before the catalytic converter). This is for Bank 1 Sensor 1, the first sensor and one that is situated closest to the engine (B1S1). While supplies last, use the link below to place an order for 59% off the standard price. Hopefully, this was useful.
