Walker Products 350-35013 oxygen sensor for the 2008-2012 Audi S5 V8 4.2L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a 5-W wide-band unit.
- Measures oxygen levels in the exhaust to help fine-tune the air-fuel ratio and support fuel economy
- 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
- Made for its specific application and position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-35013 oxygen sensor
- Fits: 2008-2012 Audi S5 V8 4.2L and other vehicles
- Position: Upstream, upstream left, upstream right, upstream rear, upstream front
- Condition: New
A failing sensor can show up as an engine that runs poorly, higher fuel consumption or a lit malfunction indicator light. Those signs can mean the sensor is worn, though a damaged wiring harness or connector can be behind them too, so inspect both for physical damage while you diagnose.
Fits
As a direct-fit replacement, this oxygen sensor fits the 2008-2012 Audi S5 V8 4.2L, the 2009 Audi A5 V6 3.2L, the 2005-2007 Cadillac CTS V6 2.8L and the 2005-2008 CTS V6 3.6L, along with many other vehicles. This listing is one sensor, and the 2008-2012 Audi S5 V8 4.2L takes one. Open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this the right Cadillac CTS oxygen sensor for the 2005-2007 V6 2.8L or the 2005-2008 V6 3.6L?
Yes. Walker Products 350-35013 fits the 2005-2007 Cadillac CTS V6 2.8L and the 2005-2008 CTS V6 3.6L, and each takes one sensor.
Is this an Audi A5 oxygen sensor for the 2009 V6 3.2L?
Yes. This sensor fits the 2009 Audi A5 V6 3.2L, which takes one.
What thread size does the Walker Products 350-35013 oxygen sensor have?
Walker Products 350-35013 has an M18 - 1.5 thread. It is a 5-W wide-band sensor.
What are the electrodes on this oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates.
What can a failing oxygen sensor cause on a newer vehicle?
A failing sensor can make the engine run poorly, increase fuel consumption or light the malfunction indicator light. Newer vehicles may also store a fault code in the ECU that relates to the sensor and its associated systems.
