The DELPHI Mass Air Flow (MAF) Sensor is engineered to precisely measure the amount of air entering the engine's intake manifold. This critical data allows the engine control unit (ECU) to calculate the correct amount of fuel to inject, leading to improved fuel efficiency and reduced emissions. Proper functioning of the MAF sensor is essential for maintaining smooth engine operation, preventing stalling, and ensuring optimal power delivery. A faulty MAF sensor can lead to various drivability issues, including rough idling, hesitation, and poor acceleration. This AF10446-12B1 sensor is designed as a direct replacement for your vehicle's original equipment, ensuring a proper fit and reliable performance. Trust DELPHI for quality components that help keep your engine running at its best.
