The DELPHI Mass Air Flow (MAF) Sensor AF10441-12B1 is engineered to precisely measure the amount of air entering the engine's intake manifold. This critical data is then sent to the engine control unit (ECU) to determine the correct amount of fuel to inject for combustion. By providing accurate airflow readings, this sensor helps the ECU optimize the air-fuel ratio, leading to improved engine performance, smoother idling, and better fuel economy. A malfunctioning MAF sensor can cause issues such as poor acceleration, engine misfires, and increased emissions. This DELPHI MAF sensor is designed to meet or exceed original equipment specifications, ensuring a reliable and direct fit for your vehicle. Trust DELPHI for quality components that maintain your engine's efficiency and responsiveness.
