O2, Oxygen Sensor (OEM-Bosch), Front, Passenger Bank 1 or Drivers Side Bank 2 for B7-RS4 or Bank 2, Cylinders 4-5 (OEM-Bosch) for D3 S8 V10

This is an OEM oxygen or O2 sensor for the front, either side of your B7-RS4. This is a Bosch OEM updated oxygen sensor. The original part number was 079906262B. It has been superseded to 1K0998262AA which now fits either side. Audi and Bosch (Audi OEM supplier for this part) have both updated this PN. We source this part directly from Bosch who is the original equipment manufacturer (OEM) for this sensor for Audi. It is exactly the same as the part that comes directly from Audi except you are not paying for the Audi logo and Audi box.

Make sure you plug into the correct connector when installing since the original sensors were keyed to only go to their side, now they plug into either side.

Please note, when diagnosing your vehicle: Bank 1 = passenger or right side and Bank 2 = driver side or left side.
