Genuine 51 74 8 091 762 Lower Active Air Flaps Assembly for M Aerodynamics Package

The Genuine BMW Lower Active Air Flaps Assembly (Part Number 51 74 8 091 762) is an original equipment radiator shutter system designed specifically for BMW vehicles equipped with the M aerodynamics package. This active grille shutter assembly mounts in the lower front bumper area and works in conjunction with your vehicle's thermal management system to optimize aerodynamics and engine cooling efficiency.

Key Features:

• Genuine BMW OEM part designed for vehicles with M aerodynamics package
• Active air flap system with integrated actuator motor
• Automatically opens and closes based on engine temperature and cooling demands
• Improves fuel efficiency by reducing aerodynamic drag when closed
• Engineered to exact BMW specifications for precise fit and reliable operation
• Mounts in lower bumper grille opening behind front fascia

This active air flap assembly uses an electric actuator to open and close the shutters as needed. When the engine is cold, the shutters remain closed to reduce aerodynamic drag and improve fuel economy. As the engine warms up and requires additional cooling, the system automatically opens the shutters to allow increased airflow to the radiator and heat exchangers. The assembly includes the complete shutter mechanism with motor, ensuring proper integration with your BMW's electronic control systems.
