Walker Products 350-34120 right oxygen sensor for the 2005-2008 Audi A6 Quattro V6 3.2L, the 2009-2011 A6 Quattro V6 3.0L and other vehicles measures the oxygen left in the exhaust gas to show how efficiently the engine burns fuel. It is a 4-wire, direct-fit, narrow-band sensor made for its specific application and position, and it gives the ECU the diagnostic feedback it needs.
- Fine-tunes the air-fuel mixture from exhaust oxygen readings to support fuel economy
- Monitors the air-fuel ratio in the exhaust for combustion efficiency
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-34120 oxygen sensor
- Fits: 2005-2008 Audi A6 Quattro V6 3.2L, the 2009-2011 A6 Quattro V6 3.0L and other vehicles

A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. Before you replace this sensor, rule out damage to its wiring harness and connector, and read any stored fault codes that point to another system.
Fits
As an Audi A6 Quattro oxygen sensor it covers the 2005-2008 V6 3.2L and the 2009-2011 V6 3.0L, and the fitment also includes the 2006-2011 Audi A6 V6 3.2L and the 2005-2009 Audi A4 Quattro V6 3.2L. Each of these cars takes one in this position. This listing is one sensor for the downstream right; the other side is a separate sensor. If your car is not named here, look it up in the "Vehicles it fits" section.
