Walker Products 250-24713 oxygen sensor for the 2007-2013 BMW 328i 6-cylinder 3.0L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a 4-wire, direct-fit, narrow-band unit made for its specific application and fitment position.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Oxygen readings help fine-tune the air-fuel mixture for fuel economy
- Exhaust gas monitoring helps reduce pollutants
- Electrodes made of a gas-permeable platinum layer
- Oxygen content of the exhaust gas is monitored to track the air-fuel ratio and combustion efficiency
- Diagnostic feedback is provided to the ECU as its application requires
Quick facts
- Part: Walker Products 250-24713 oxygen sensor
- Fits: 2007-2013 BMW 328i 6-cylinder 3.0L and other vehicles
- Position: Downstream, downstream left, downstream right, downstream front
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light, and newer vehicles may store fault codes in the ECU. Before you replace the sensor, rule out damage to its wiring harness and connector, which you can look over with the engine off.
Fits
As a BMW 328i oxygen sensor replacement, it covers the 2007-2013 model with the 6-cylinder 3.0L. It is also listed for a wide range of other BMW models, led by the 2008-2010 BMW X6 6-cylinder 3.0L and the 2008-2019 X6 V8 4.4L, and the 2013-2019 BMW 650i Gran Coupe V8 4.4L. This listing is one sensor, and each application takes one in the downstream position.

Frequently Asked Questions
Is the Walker Products 250-24713 the right BMW 328i oxygen sensor for a 2007-2013 model with the 6-cylinder 3.0L?
Yes. Walker Products 250-24713 is listed for the 2007-2013 BMW 328i 6-cylinder 3.0L. To check a different car, look it up in the "Vehicles it fits" section.
Is the Walker Products 250-24713 an upstream or a downstream sensor?
Walker Products 250-24713 is a downstream oxygen sensor. Its position is listed as downstream, downstream left, downstream right and downstream front.
Is this oxygen sensor narrow-band or wideband?
This oxygen sensor is narrow-band, with four wires and a direct-fit design made for its specific application and fitment position.
What does the coating on this oxygen sensor do?
The coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gas. The electrodes themselves are made of a gas-permeable platinum layer.
How does this narrow-band sensor help with fuel economy and emissions?
This sensor measures the oxygen in the exhaust gas so the air-fuel ratio can be monitored for combustion efficiency. Those readings help fine-tune the mixture for fuel economy and help reduce pollutants.
