The DELPHI Mass Air Flow (MAF) Sensor, part number AF10430-12B1, is a critical component for modern engine management systems. It precisely quantifies the volume and density of air entering the engine's intake manifold. By providing this crucial data to the Engine Control Unit (ECU), the MAF sensor enables accurate calculations for fuel injection timing and quantity. This leads to improved fuel efficiency, reduced emissions, and smoother engine operation. This sensor is designed to meet or exceed original equipment specifications, ensuring reliable and consistent performance. Proper functioning of the MAF sensor is essential for maintaining engine power and responsiveness across various driving conditions.
