Walker Products 250-241161 right oxygen sensor for the 2014-2021 BMW i3 2-cylinder 0.6L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. This Walker Products oxygen sensor is a narrow-band, 4-W direct-fit unit made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it needs.
- Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes made with a gas-permeable platinum layer

Frequently Asked Questions
Does the 250-241161 downstream oxygen sensor fit the 2014-2021 BMW i3 2-cylinder 0.6L?
Yes, Walker Products 250-241161 fits the 2014-2021 BMW i3 2-cylinder 0.6L and the 2016-2021 BMW M2 6-cylinder 3.0L. If your car is not named here, look up your year, model and engine in the "Vehicles it fits" section.
What thread size does this downstream oxygen sensor have?
Walker Products 250-241161 has an M18 - 1.5 thread. It is a narrow-band, 4-W direct-fit sensor.
Is this Walker Products oxygen sensor sold as a single piece?
Yes. This listing is one sensor for the downstream right position, and the fitment lists a quantity of 1 for it.
What does the coating on this oxygen sensor do?
The coating keeps combustion residue and particulates in the exhaust gas from contaminating and eroding the electrode surfaces. The electrodes carry a gas-permeable platinum layer.
How can I tell if this oxygen sensor is going bad?
Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read those codes and test the sensor.
