Mercedes Benz C Class S203 C200K M111 01-07 4 Wire 420mm Lambda Oxygen Sensor OE 15400517

High-quality replacement lambda oxygen sensor designed for the Mercedes-Benz C-Class S203 C200 Kompressor equipped with the reliable M111 petrol engine. Featuring a 4-wire configuration and 420mm 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.
