Walker Products 350-35131 oxygen sensor for the 2012-2016 BMW 328i 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. This Walker Products oxygen sensor is a wide-band unit for the upstream position.
- Measures oxygen levels in the exhaust to help fine-tune the air-fuel mixture
- Electrodes made of a gas-permeable platinum layer
- Electrode coating guards against contamination and erosion from combustion residue and particulates in the exhaust gases
- Wide-band design that monitors the air-fuel ratio for combustion efficiency
- Monitors exhaust gases to help reduce pollutants
- Built for its specific application and position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-35131 oxygen sensor
- Fits: 2012-2016 BMW 328i 4-cylinder 2.0L and other vehicles
- Position: Upstream
- Condition: New
A failing sensor can show up as the engine running poorly, higher fuel consumption or a lit malfunction indicator light. A damaged wiring harness or connector can be behind these signs too, so look both over for physical damage with the engine off and cool, and find the cause before you buy a new sensor.
Fits
For the 2012-2016 BMW 328i 4-cylinder 2.0L it is a direct-fit oxygen sensor replacement, and it also fits the 2013-2018 BMW 320i 4-cylinder 2.0L and the 2013-2018 BMW 320i xDrive 4-cylinder 2.0L. If your BMW is not named here, look up its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for the 2012-2016 BMW 328i 4-cylinder 2.0L?
Yes. Walker Products 350-35131 is listed for the 2012-2016 BMW 328i 4-cylinder 2.0L as an upstream sensor, and that car takes one.
Does this oxygen sensor fit a 2013-2018 BMW 320i 4-cylinder 2.0L?
Yes. Walker Products 350-35131 is listed for the 2013-2018 BMW 320i 4-cylinder 2.0L, and for the 2013-2018 BMW 320i xDrive 4-cylinder 2.0L as well.
What thread size does this wide-band upstream oxygen sensor use?
This wide-band sensor has an M18 - 1.5 thread. It is made for the upstream position.
What can a worn upstream oxygen sensor do to the way a car runs?
Signs can include the engine running poorly, more exhaust emissions or a lit malfunction indicator light. A shop can read the fault codes the ECU stores.
What is the platinum layer on this Walker Products sensor for?
The electrodes are made of a gas-permeable platinum layer. Its coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
