Walker Products 350-34142 oxygen sensor for the 2014-2016 BMW X6 V8 4.4L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. This Walker Products oxygen sensor is a 4-wire, direct-fit, narrow-band unit.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Made for its specific application and position on the vehicle, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-34142 oxygen sensor
- Fits: 2014-2016 BMW X6 V8 4.4L and other vehicles
- Position: Upstream, upstream left, upstream right, downstream left, downstream right
- Condition: New
Newer vehicles store fault codes in the ECU, and some point to the sensor. A failing sensor can show up as rough running, higher fuel use or a lit malfunction indicator light, though the wiring harness and connector can be behind those signs as well, so inspect both for physical damage before you replace the sensor.
Fits
As a direct-fit narrow-band sensor, it fits the 2014-2016 BMW X6 V8 4.4L, the 2000-2003 BMW X5 V8 4.4L, the 2001-2006 X5 6-cylinder 3.0L, the 2002-2003 X5 V8 4.6L and the 2003-2006 BMW Z4 6-cylinder 2.5L or 3.0L. This listing is one sensor, and the BMWs named here take a single one. Driving something else? Run your year, model and engine through the "Vehicles it fits" section.
