The DELPHI Mass Air Flow (MAF) Sensor, part number AF10634-12B1, 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 combustion. Proper functioning of the MAF sensor is vital for maintaining fuel efficiency, reducing emissions, and ensuring smooth engine operation. A faulty MAF sensor can lead to various drivability issues, including rough idling, hesitation, stalling, and poor acceleration. This DELPHI sensor is designed to meet or exceed original equipment specifications, providing a reliable and direct fit for your vehicle. Trust DELPHI for quality components that contribute to your engine's overall health and performance.
