The DELPHI Mass Air Flow Sensor (AF10703-12B1) 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 smooth idling, responsive acceleration, and optimal fuel economy. A faulty sensor can lead to various drivability issues, including poor performance, increased emissions, and potential engine warning lights. DELPHI is a trusted brand known for its quality automotive components. This sensor is designed to meet or exceed original equipment specifications, providing a reliable replacement for your vehicle's air intake system.
