Walker Products 350-35135 oxygen sensor for the 2019-2026 Audi A8 Quattro V6 3.0L and other vehicles measures the oxygen in the exhaust gas to show how completely the engine burns its fuel.
- Monitors exhaust gases and the air-fuel ratio to track combustion efficiency
- Coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates
- Oxygen readings are used to fine-tune the air-fuel mixture, which supports fuel economy
- 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 350-35135 oxygen sensor
- Fits: 2019-2026 Audi A8 Quattro V6 3.0L and other vehicles
- Position: Upstream, upstream right, upstream rear
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and those symptoms can start elsewhere in the engine too. With the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage before you replace anything.
Fits
It also fits the 2019-2026 Audi Q8 V6 3.0L and the 2020-2026 Audi A6 Allroad V6 3.0L, among many other vehicles. If your car is not one of these, open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is the Walker Products 350-35135 right for the 2019-2026 Audi Q8 V6 3.0L?
Yes. Walker Products 350-35135 fits the 2019-2026 Audi Q8 V6 3.0L, and that engine takes one sensor.
What kind of sensor is the Walker Products 350-35135?
Walker Products 350-35135 is a 5-W wide-band oxygen sensor with electrodes made of a gas-permeable platinum layer.
What symptoms can a failing wide-band oxygen sensor cause?
The engine can run poorly, fuel consumption and exhaust emissions can rise, or the malfunction indicator light can come on. Those signs can start elsewhere too, so a shop can confirm the cause.
Does the coating on this oxygen sensor protect the electrodes?
Yes. The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gas.
Do I get one sensor or two in this oxygen sensor listing?
You get one sensor. The listing is a single oxygen sensor, and each vehicle application takes one.
