This Mass Air Flow (MAF) sensor from DELPHI is designed to accurately measure the volume and density of air entering the engine. By providing precise air intake data to the engine control unit (ECU), this sensor is crucial for calculating the correct amount of fuel to inject. This leads to improved fuel efficiency, reduced emissions, and consistent engine performance. Crafted with high-quality materials, the AF10653-12B1 ensures reliable operation and durability. It is a direct fit replacement for your vehicle's original MAF sensor, making installation straightforward.
