Genuine BMW 51-74-7-493-167 Active Grille Shutter Actuator Motor

The Genuine BMW Active Grille Shutter Actuator Motor (part number 51-74-7-493-167) is an OEM replacement component designed to control the upper active grille shutter system on BMW X3 G01 and X4 G02 models. This electric motor-driven actuator automatically opens and closes the grille shutters to optimize airflow through the front grille, improving both aerodynamic efficiency and engine thermal management.

Key Features and Benefits:

• Genuine BMW OEM part ensuring perfect fit and factory-level quality
• Controls active grille shutters to reduce aerodynamic drag at highway speeds, improving fuel efficiency
• Helps engine reach optimal operating temperature faster during cold starts by closing shutters
• Opens shutters when cooling is needed to maintain proper engine temperature
• Reduces CO2 emissions through improved vehicle aerodynamics
• Manufactured from durable ABS materials designed to withstand varying weather conditions
• Direct replacement for worn, corroded, or malfunctioning original actuator motors

When the active grille shutter actuator fails, it can cause check engine lights, fault codes, reduced fuel economy, and compromised engine cooling. This genuine BMW replacement part restores proper operation of the active grille shutter system, ensuring the louvers open and close as designed based on vehicle speed, engine temperature, and cooling demands. The actuator is located behind the front grille and operates the upper shutter assembly that controls airflow into the engine compartment.

Technical Information: This is the upper active grille shutter actuator motor, also referred to as "Air Flap Control, Active, Up" or "AKTOR" in BMW parts diagrams. Alternate part number formats include 51747493167, 51 74 7 493 167, and 51.74.7.493.167.
