汽车氧传感器0258006948 原厂替代 稳定耐用

When your vehicle experiences unstable idling, abnormal fuel consumption, sluggish acceleration, or an engine fault light, it is likely the oxygen sensor has aged or failed and is causing the air-fuel ratio to go out of control. When functioning, it monitors oxygen in the exhaust and feeds signals to the ECU to precisely adjust fueling, ensuring combustion efficiency and emission compliance. This is an OEM replacement with OEM number 0258006948, compatible with Wuling, Changan, BAIC, Baojun and other mainstream models. During installation, be sure to use a dedicated socket, avoid over-torquing threads, and clean the installation seat to prevent debris from entering the exhaust.
