Bosch an OEM supplier often consolidates part numbers and this is one of those cases, this sensor works on either side and comes with a connector that will need to be swapped out on the engine harness in some cases. This is standard practice by Bosch and Audi once cars get in the 10 year to 15 year plus range in age. This updated part fits either side for all the vehicles mentioned in our fitment chart below and more. We highly recommend replacing both as a pair. NOTE: Picture does not show the connector but it comes in the kit. These Front O2 sensors are made by Bosch the OEM manufacturer. Both the left and right side Front (Primary) 02 sensors use the same part number. Please Note, when diagnosing your vehicles: Bank 1 = passenger's side/right, and Bank 2 = driver's side/left. 2 per vehicle, adjust the quantity to 2 at checkout if you want both.
