The DELPHI Mass Air Flow (MAF) Sensor, part number AF10375-12B1, 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 efficient combustion. Proper functioning of the MAF sensor is vital for maintaining optimal engine performance, fuel economy, and emissions control. A failing MAF sensor can lead to a range of issues, including rough idling, poor acceleration, increased fuel consumption, and illuminated check engine lights. DELPHI is a trusted brand known for its high-quality automotive components. This AF10375-12B1 sensor is designed to meet or exceed original equipment specifications, providing a reliable replacement for your vehicle's existing MAF sensor.
