Mazda Mass Airflow Sensor - P/N # FS1E-13-215

This Mass Airflow Sensor is a genuine OEM-specification replacement for compatible Mazda vehicles, identified by part number FS1E-13-215. The mass airflow (MAF) sensor plays a critical role in your engine's management system, continuously measuring the volume and density of air entering the intake. This data is sent to the engine control unit (ECU), which uses it to calculate the precise amount of fuel to inject for optimal combustion. A faulty or failing MAF sensor can cause a range of drivability issues including rough idling, poor fuel economy, hesitation under acceleration, and illumination of the check engine light. Replacing the sensor with a correct OEM-spec unit restores factory-standard accuracy and reliability.
