Oxygen Sensor for 2007-2012 Mini Cooper & More - Walker 350-35030

Walker Products 350-35030 oxygen sensor for the 2007-2012 Mini Cooper 4-cylinder 1.6L and other vehicles measures the oxygen in the exhaust gas to track combustion efficiency. This wide-band Walker Products oxygen sensor sends the ECU the diagnostic feedback it expects for its application and position.

• Monitors exhaust gases and reduces pollutants for a cleaner environment
• Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas
• Electrodes made of a gas-permeable platinum layer
• Measures oxygen levels so the air-fuel mixture can be fine-tuned, which supports fuel economy
• Determines the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency

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 at fault, because a worn spark plug can also make an engine run poorly. Inspect the sensor's wiring harness and connector for physical damage with the engine off and cool. This listing is one sensor, and each fitted position takes one.

Fits

Vehicles it fits include the 2016-2019 Mercedes-Benz GLC300 4-cylinder 2.0L and the 2017-2018 Mercedes-Benz SL450 V6 3.0L, along with many more. If your car is not one of these, find its year and engine in the "Vehicles it fits" section.
