宝马5系氧传感器 11787512983 原厂品质直接替换

For BMW 5 Series (F10/F11/F18 chassis) with N52 or N55 engines, the oxygen sensor part 11787512983 can be used as a direct replacement for the OEM, and is also a universal substitute for Bosch 0258017038. Suitable for 1 Series (E81/E82/E87/E88) and some 3 Series, X1 models. Monitors exhaust oxygen content and feeds ECU to adjust air–fuel ratio, improving fuel economy. After installation, it resolves idle instability, weak acceleration, high fuel consumption, and eliminates the engine warning light. If the vehicle has starting difficulties or exhaust emits black smoke or fuel consumption spikes, oxygen sensor aging is likely; replace promptly.
