The DELPHI AF10281-12B1 Mass Air Flow (MAF) sensor is engineered to precisely measure the amount of air entering the engine's intake manifold. This critical data is then sent to the engine control unit (ECU) to determine the correct amount of fuel to inject for optimal combustion. By providing accurate airflow readings, this sensor helps to maintain consistent engine performance, improve fuel economy, and reduce harmful emissions. A malfunctioning MAF sensor can lead to poor acceleration, rough idling, increased fuel consumption, and check engine lights. Designed as a direct replacement, the AF10281-12B1 ensures compatibility and ease of installation, minimizing downtime. Trust DELPHI for reliable and high-quality engine management components that keep your vehicle running smoothly.
