BMW 5 Series E39 520 523 528 530 535 540 M5 M52 M54 M62 S62 4 Wire 320mm Lambda Oxygen Sensor OE 11781742050
High-quality replacement lambda oxygen sensor designed for BMW 5 Series E39 models, including 520, 523, 528, 530, 535, 540, and M5 variants equipped with M52, M54, M62, and S62 petrol engines. Featuring a 4-wire configuration and 320mm lead length, this sensor is manufactured to OE specifications to accurately monitor oxygen levels in the exhaust system and communicate with the engine control unit (ECU) to maintain the optimal air-fuel mixture for efficient combustion, improved fuel economy, and reduced emissions.
A worn or faulty oxygen sensor can cause increased fuel consumption, rough idling, poor engine performance, hesitation during acceleration, excessive exhaust emissions, and illumination of the check engine light. Replacing a defective sensor helps restore engine efficiency, improve drivability, and maintain proper catalytic converter operation.
