北斗星氧传感器 F01R00C018 原厂替换件

When your Beidouxing (Beidou Star) exhibits idle instability, sluggish acceleration, or noticeably higher fuel consumption or the engine check light is on, oxygen sensor aging or failure is likely, unable to accurately monitor exhaust oxygen content. This sensor, when operating normally, feeds the ECU with air–fuel ratio signals to ensure efficient catalytic converter purification and optimize fuel economy. This product is a genuine OEM replacement, OEM number F01R00C018, suitable for Beidouxing series models (e.g., 1.0L/1.4L). Installation notes: disconnect the negative battery first, wait for the exhaust to cool, avoid damaging threads; installation torque recommended as 45–55 N·m; apply anti-seize to threads to prevent sintering.
