Genuine 51 13 7 497 227 Upper Radiator Active Grille Shutter Assembly

The Genuine BMW Upper Radiator Shutter Assembly (Part Number 51 13 7 497 227) is an OEM active grille shutter system designed to optimize aerodynamics and engine cooling performance. This active aerodynamics component automatically opens and closes to control airflow through the front grille, improving fuel efficiency while maintaining proper engine temperature management.

Key Features:

• Genuine BMW OEM part ensuring perfect fit and factory specifications
• Active grille shutter technology that automatically adjusts based on driving conditions
• Reduces aerodynamic drag when closed, improving fuel economy by up to 2%
• Opens to provide maximum cooling airflow when engine temperatures rise
• Accelerates engine warm-up in cold weather conditions
• Upper position mounting for optimal airflow management
• Integrated motor and control module for precise operation
• Built from durable materials to withstand extreme temperatures and front-end airflow

This radiator shutter assembly works in conjunction with the vehicle's powertrain control module to monitor engine temperature, vehicle speed, and cooling requirements. When cooling is not needed, the shutter closes to create a smoother airflow around the vehicle, reducing drag and lowering CO2 emissions. The system performs an automatic calibration cycle at each vehicle startup to ensure proper operation.
