Keep the engine's air-fuel feedback accurate with the Walker Products Oxygen Sensor 350-35099, a wide-band, heated 5-wire sensor that reads the oxygen content of the exhaust gas so the ECU can monitor the air-fuel ratio and combustion efficiency. It installs as a direct-fit, OE-replacement sensor for the 2012-2014 Audi A8 Quattro [W12-6.3L].
Features:
Wide-band, heated design: a 5-wire heated sensor that determines the oxygen content of the exhaust gas to help the ECU fine-tune the air-fuel mixture.
Platinum electrodes: electrodes made of a gas-permeable platinum layer.
Protective coating: a coating helps prevent contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gas.
Connection: threaded mounting with male spade terminals and a male oblong connector, using 20-gauge wiring.
Walker Products manufactures each engine-management sensor for its specific application and fitment position, providing the diagnostic feedback the ECU expects. Signs the original sensor may need replacing include poor running, higher fuel consumption, increased exhaust emissions, or an illuminated malfunction indicator lamp (MIL); inspect the sensor, wiring harness, and connector for physical damage first, since other faults can produce the same symptoms. Grade: Standard Replacement. Country of origin: United States. Manufacturer part number 350-35099.
Frequently Asked Questions
What vehicle does the Walker 350-35099 oxygen sensor fit?
It's a direct-fit replacement for the 2012-2014 Audi A8 Quattro with the W12-6.3L engine. Check the Buyer's Guide tab to confirm it matches your vehicle.
What type of oxygen sensor is this?
It's a wide-band, heated 5-wire oxygen sensor that reads the oxygen content of the exhaust gas so the ECU can monitor the air-fuel ratio and combustion efficiency.
How does an oxygen sensor work?
It measures the amount of oxygen in the exhaust gas, giving the ECU feedback on the air-fuel ratio so it can adjust the mixture for combustion efficiency.
What are signs this oxygen sensor may need replacing?
Poor engine running, higher fuel consumption, increased emissions, or an illuminated MIL can be signs, but inspect the wiring and connector too, since other faults cause similar symptoms.
What connector and mounting does it use?
It has a threaded mount with male spade terminals and a male oblong connector, wired with 20-gauge wiring.
