The DELPHI Mass Air Flow (MAF) Sensor, part number AF10649-12B1, is engineered to precisely measure the amount of air entering your engine's intake system. This critical data is then sent to the engine control unit (ECU) to determine the correct amount of fuel to inject, ensuring efficient combustion and optimal power output. By accurately monitoring airflow, this sensor helps to maintain the ideal air-fuel ratio, which is essential for reducing emissions and improving fuel economy. A malfunctioning MAF sensor can lead to poor engine performance, increased fuel consumption, and check engine lights. This DELPHI sensor is built to meet stringent quality standards for durability and consistent performance. Installation is straightforward as this sensor is designed as a direct replacement for your original equipment. Trust DELPHI for high-quality engine management components that help keep your vehicle running smoothly and efficiently.
