Translating description...
This is an aftermarket O2 sensor set (front and rear, 2 pieces) for BMW MINI Cooper R55, R56, and R57.
Compatible vehicles: BMW MINI R55 Cooper One / R56 Cooper One / R57 Cooper. Genuine part numbers: Upstream 11787560957 / 11787590713, Downstream 11787548961. Set contents: O2 sensor set (front and rear, 2 pieces).
The O2 sensor is a crucial part that detects oxygen in exhaust gas, acting as an air-fuel ratio sensor.
Current engines are controlled by computers, which measure the air-fuel ratio based on the amount of oxygen remaining after combustion.
Symptoms of a malfunctioning O2 sensor include decreased fuel efficiency, excessive soot buildup on the inside of the muffler, and the illumination of the engine warning light.
Even if the malfunction doesn't immediately affect driving, it will put a strain on the engine and eventually lead to failure.
Even if not malfunctioning, the replacement interval for an O2 sensor is approximately 5 years.
Caution is advised for vehicles with high mileage or older model years.
Replacement can be cost-effective by using reasonably priced aftermarket parts that are equivalent to genuine parts, rather than expensive genuine parts.
This is a set of 2 O2 sensors (front and rear), making it a great value.
Prevent engine trouble and maintain optimal performance for just a few thousand yen; regular replacement is recommended.
To ensure your beloved car lasts a long time, use these as replacement parts for inspection and maintenance.
If you feel something is wrong or unusual, it's important to replace it promptly.
Having spare parts in your garage while they are available will provide peace of mind, allowing for maintenance when needed.
