The DELPHI AF10178-12B1 Mass Air Flow (MAF) sensor is engineered to precisely measure the volume and density of air entering the engine's intake system. This critical data is then transmitted to the engine control unit (ECU), allowing it to calculate the correct amount of fuel to inject for efficient combustion. Proper functioning of the MAF sensor is vital for maintaining engine performance, fuel economy, and reducing emissions. A faulty sensor can lead to various drivability issues, including rough idling, hesitation, poor acceleration, and illuminated check engine lights. This DELPHI MAF sensor is designed as a direct replacement for the original equipment, ensuring a seamless fit and reliable operation. Trust DELPHI for quality components that help keep your engine running smoothly and efficiently.
