The DELPHI Mass Air Flow Sensor (AF10655-12B1) is engineered to precisely measure the amount of air entering the engine's intake manifold. This critical data is then relayed to the engine control unit (ECU), allowing for precise fuel injection calculations. By providing accurate airflow readings, this sensor helps to optimize the air-fuel mixture, leading to improved fuel efficiency and reduced emissions. A malfunctioning MAF sensor can cause a range of issues, including rough idling, poor acceleration, and increased fuel consumption. This DELPHI MAF sensor is designed to meet or exceed original equipment specifications, ensuring reliable and consistent performance. Its robust construction is built to withstand the demanding conditions within the engine bay, offering durability and longevity.
