宝马5系氧传感器11787589146 0258010424 0258010160 通用型 精准空燃比控制

Oxygen sensor directly replaces BMW original part number 11787589146, also compatible with 0258010424 and 0258010160. Universal design; no need to worry about original parts. Its core function is to monitor exhaust oxygen content and provide feedback to the ECU to precisely control the air-fuel ratio, ensuring engine combustion efficiency. Fits BMW 5 Series (E60/E61 chassis) especially N52, N54 engine models. After installation, it can resolve high fuel consumption, sluggish acceleration, and excessive exhaust emissions, and can eliminate the engine warning light. If you notice rough idle, black smoke from the exhaust, or fuel economy suddenly dropping by 1-2 mpg, the oxygen sensor is likely aging—replace promptly.
