The Ford 3L3A-12B579-BA Mass Airflow Meter MAF Sensor in durable ABS plastic is a precise, plug-and-play solution designed to restore accurate air measurement for Ford Focus II models. By constantly monitoring air inflow and intake air temperature, it helps the engine control unit optimize fuel delivery and idle speed. The result is smoother idle, steadier throttle response, and improved overall driving efficiency, especially when the original MAF sensor has worn or failed.

This mass airflow sensor is a direct replacement that uses the OEM reference 3L3A-12B579-BA and is engineered to fit Ford Focus II four-door sedans (2004–2012), including 2005 models and second-generation station wagons (2004–2012). The ABS housing provides a robust, heat- and vibration-resistant shell, while the sensor’s electrical connections align with the vehicle’s harness for straightforward installation. Color is shown in the listing image.
