The DELPHI Mass Air Flow (MAF) Sensor, part number AF10738-12B1, is engineered to precisely measure the amount of air entering your engine's intake manifold. This critical data is then sent to the engine control unit (ECU) to calculate the correct amount of fuel to inject, ensuring optimal combustion. By providing accurate airflow readings, this sensor helps maintain consistent engine performance, improves fuel economy, and reduces harmful emissions. A malfunctioning MAF sensor can lead to poor acceleration, rough idling, increased fuel consumption, and check engine lights. This DELPHI MAF sensor is designed for reliable and durable operation, meeting stringent quality standards. It is a direct fit replacement for your original equipment, ensuring compatibility and ease of installation. Trust DELPHI for high-quality engine management components that keep your vehicle running smoothly.
