Oxygen Sensor

The Bosch Mass Air Flow (MAF) Sensor is a direct replacement for your vehicle's original equipment. This hot film sensor is manufactured in Germany to OE specifications, ensuring it functions correctly with your engine's computer to precisely measure the volume and density of air entering the intake. Accurate MAF readings are crucial for the fuel injection system to deliver the optimal amount of fuel, thereby enhancing performance, improving fuel efficiency, and maintaining emissions standards. A faulty MAF sensor can lead to various issues, including illuminated check engine lights with specific MAF sensor fault codes, rough idling, stalling, and incorrect fuel trim readings (running rich or lean). Diagnosing a faulty sensor can sometimes be as simple as temporarily disconnecting it to see if engine performance improves. This Bosch Mass Air Flow Sensor (part number 0280217515) is compatible with a range of Mercedes-Benz models, including the C240, C280, C320, C32 AMG, CLK320, E320, ML320, ML350, S350, SLK320, and SLK32 AMG. Specific fitment details, including exact years, engine sizes, and transmission types, are available in the product's fitment guide.
