Walker Products 350-35078 oxygen sensor for the 2007-2013 BMW 328i 6-cylinder 3.0L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a wide-band unit that monitors the air-fuel ratio for combustion efficiency.
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
- Monitors exhaust gases, which helps reduce pollutants
- Made for a specific application and position on the vehicle, with the diagnostic feedback the ECU requires
Quick facts
- Part: Walker Products 350-35078 oxygen sensor
- Fits: 2007-2013 BMW 328i 6-cylinder 3.0L and other vehicles
- Position: Upstream, upstream left, upstream right, upstream front

Frequently Asked Questions
Is this BMW 328i oxygen sensor right for the 2007-2013 6-cylinder 3.0L?
Yes. Walker Products 350-35078 is listed for the 2007-2013 BMW 328i 6-cylinder 3.0L with a quantity of one. For a different car, use the "Vehicles it fits" section.
Is this BMW 328i oxygen sensor replacement for the 2007-2013 6-cylinder 3.0L a wide-band sensor?
Yes. Walker Products 350-35078 is a wide-band oxygen sensor, listed as 5-W wide-band, and it sits upstream in the exhaust.
How many sensors come in the Walker Products 350-35078 listing?
This listing is one oxygen sensor, and the fitment lists a quantity of one per application.
What does the coating on this Walker oxygen sensor protect?
The coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates in the exhaust gases. The electrodes are a gas-permeable platinum layer.
Can a worn wide-band oxygen sensor turn on the check engine light?
Yes, a failed sensor can light the malfunction indicator light, and newer vehicles store fault codes in the ECU. A shop can read the stored codes to find what is behind the light.
