宝马5系配件 氧传感器11787589147 0258010424 0258010160 稳定信号输出

This oxygen sensor directly replaces BMW original 11787589147 and is compatible with 0258010424 and 0258010160, a universal substitute not sensitive to batch. It monitors exhaust oxygen content and stabilizes signal to the ECU to ensure precise air-fuel ratio control. Fits BMW 5 Series (F10/F11 chassis) and some models with N52 or N55 engines. After install, it can relieve rough idle, high fuel consumption, and acceleration sluggishness; emissions meet standards. If the engine check light is on, fuel consumption jumps by over 10%, or there is noticeable shaking after cold start, this sensor is aging and should be replaced.
