This Mass Air Flow (MAF) sensor from DELPHI is engineered to accurately measure the volume and density of air entering the engine's intake system. By providing precise air intake data to the engine control unit (ECU), this sensor enables the ECU to calculate the correct amount of fuel to inject for optimal combustion. This leads to improved engine performance, better fuel economy, and reduced emissions. Crafted with high-quality materials and advanced sensor technology, the AF10148-12B1 is designed for durability and reliable operation under various driving conditions. It is a direct fit replacement for your original equipment MAF sensor.
