Walker Products 250-24465 oxygen sensor for the 2007-2013 BMW 328i 6-cylinder 3.0L and other vehicles measures the oxygen content of the exhaust gas to show combustion efficiency. This Walker Products oxygen sensor is a 4-wire, direct-fit, narrow-band design for the downstream position.
- Monitors exhaust gases to help reduce pollutants
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
- Made for its specific application and fitment position, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 250-24465 oxygen sensor
- Fits: 2007-2013 BMW 328i 6-cylinder 3.0L and other vehicles
- Position: Downstream, downstream left, downstream right, downstream rear
- Condition: New
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem; a vacuum leak can produce some of the same symptoms. With the engine off and cool, look the sensor, wiring and connector over for damage.
Fits
This direct-fit oxygen sensor replacement is listed for the 2007-2013 BMW 328i 6-cylinder 3.0L, and for a wide range of other BMW and Mercedes-Benz models, led by the 2014-2019 BMW M6 Gran Coupe V8 4.4L and the 2012-2018 BMW M6 V8 4.4L. If your car is not one of these, search its year and engine in the "Vehicles it fits" section to see where it is listed.

Frequently Asked Questions
Is this the right BMW 328i oxygen sensor for a 2007-2013 6-cylinder 3.0L engine?
Yes. Walker Products 250-24465 is listed for the 2007-2013 BMW 328i 6-cylinder 3.0L, in the downstream position, with a quantity of one.
What thread size does this narrow-band oxygen sensor have?
Walker Products 250-24465 has an M18 - 1.5 thread. It is a 4-wire, narrow-band, direct-fit sensor.
Is this a downstream oxygen sensor?
Yes. The catalog lists this sensor for the downstream position, including downstream left, downstream right and downstream rear.
What does the platinum layer on this oxygen sensor do?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases.
Will a failing oxygen sensor set a fault code?
Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its systems. A shop can read those codes to see whether the sensor is involved.
