The DELPHI Mass Air Flow (MAF) Sensor, part number AF10303-12B1, 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 help determine the correct amount of fuel to inject for efficient combustion. Proper functioning of the MAF sensor is vital for maintaining smooth engine operation, fuel economy, and reducing emissions. A faulty MAF sensor can lead to various drivability issues, including rough idling, hesitation, stalling, and poor acceleration. This DELPHI MAF sensor is designed as a direct replacement for your original equipment, ensuring a perfect fit and straightforward installation. Rely on DELPHI's expertise for a high-quality component that restores your vehicle's performance and reliability.
