The DELPHI Mass Air Flow (MAF) Sensor, part number AF10498-12B1, is engineered to precisely measure the amount of air entering your engine's intake manifold. This critical data is then sent to the engine control unit (ECU) to help determine the correct amount of fuel to inject for combustion. Accurate airflow readings are essential for maintaining optimal engine performance, fuel efficiency, and emissions control. A malfunctioning MAF sensor can lead to a range of issues, including poor acceleration, rough idling, increased fuel consumption, and check engine lights. This DELPHI MAF sensor is built to meet or exceed original equipment specifications, providing a dependable replacement for your vehicle. Its robust construction and precise calibration ensure consistent and reliable performance throughout its service life.
