Walker Products 350-341093 oxygen sensor for the 2021-2024 Mini Cooper 4-cylinder 2.0L, the 2022-2024 Cooper 3-cylinder 1.5L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. Each Walker part number is made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it needs.
- Narrow-band design with 4 wires
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Measures exhaust oxygen to fine-tune the air-fuel mixture for fuel economy
- Monitors exhaust gases and the air-fuel ratio for combustion efficiency
Quick facts
- Part: Walker Products 350-341093 oxygen sensor
- Fits: 2021-2024 Mini Cooper 4-cylinder 2.0L, the 2022-2024 Cooper 3-cylinder 1.5L and other vehicles

A failing sensor can show up as a rough-running engine, higher fuel use, more exhaust emissions or a lit malfunction indicator light. Those signs can have other sources, so find the cause first; with the engine off and cool, look the sensor, wiring harness and connector over for physical damage.
Fits
The 2022-2025 BMW M8 V8 4.4L and the 2020-2025 BMW M8 Gran Coupe V8 4.4L are among the many BMW and Mini models this oxygen sensor fits. If your car is not named here, find its year and engine in the "Vehicles it fits" section. This listing is one sensor, and the 2021-2024 Mini Cooper 4-cylinder 2.0L takes one.

Frequently Asked Questions
Is this Mini Cooper oxygen sensor right for the 2021-2024 model with the 4-cylinder 2.0L engine?
Yes. Walker Products 350-341093 fits the 2021-2024 Mini Cooper 4-cylinder 2.0L and the 2022-2024 Cooper 3-cylinder 1.5L, and each takes one sensor.
Does this sensor fit the 2022-2025 BMW M8 V8 4.4L?
Yes. It fits the 2022-2025 BMW M8 V8 4.4L and the 2020-2025 BMW M8 Gran Coupe V8 4.4L, one sensor per vehicle.
Is this Walker Products oxygen sensor narrow-band or wideband?
It is narrow-band. Walker Products 350-341093 uses 4 wires and measures the oxygen content of the exhaust gas.
What thread size does this oxygen sensor have?
The thread size is M18 - 1.5. The sensor is a threaded, direct-fit design.
Can a failing oxygen sensor turn on the check engine light?
It can. A failed sensor can make the engine run poorly, raise fuel use and emissions, or light the malfunction indicator light, and newer vehicles store fault codes in the ECU.
