51747400006 Duct | Wheel Arch Aerodynamic Cooling Optimizer for BMW M3/M4/3 Series

BMW Air Duct, Brake, Wheel Arch, Right 51747400006 51747400006 Duct Thermal Management System

Engineered for optimized brake cooling performance, the BMW Air Duct, Brake, Wheel Arch, Right 51747400006 51747400006 Duct directs high-velocity airflow to critical braking components during aggressive driving conditions. This structural guide channel utilizes rotational-molded polypropylene with 20% mineral reinforcement for impact resistance against road debris while maintaining flexibility across temperature extremes. Aerodynamically tested surface contours accelerate laminar airflow by 18% compared to conventional designs, effectively reducing brake rotor temperatures during track use or mountain descents. The BMW Air Duct, Brake, Wheel Arch, Right 51747400006 51747400006 Duct features integrated mounting tabs that align with factory bumper reinforcement points, ensuring secure installation without modifying existing fasteners. Internal ribbing prevents harmonic resonance at speeds exceeding 160km/h while hydrophobic polymer blends resist salt corrosion and chemical degradation from road treatments. Precision-engineered inlet scoops maintain optimal airflow volumes even when partially obstructed by snow or leaves, with self-cleaning channels that purge accumulated debris through centrifugal force. Color-stabilized material formulation preserves original matte black appearance despite prolonged UV exposure, while impact-dampening flex joints absorb vibration energy to prevent stress fractures in adjacent body panels.

BMW Air Duct, Brake, Wheel Arch, Right 51747400006 51747400006 Duct Vehicle Fitment

Specifically developed for G-series BMW platforms, this thermal management component provides perfect compatibility with G20 3 Series sedans (2019-2025), G22/G23 4 Series coupes (2020-2025), and G80/G82 M3/M4 performance models equipped with factory brake cooling packages. Verified fitment extends to vehicles with both standard and M Sport body kits, maintaining proper clearance for adaptive cruise control radar arrays and parking sensor clusters. The BMW Air Duct, Brake, Wheel Arch, Right 51747400006 51747400006 Duct accommodates wheel sizes ranging from 18" to 20" without interfering with tire rotation or suspension geometry changes. Production coverage includes vehicles manufactured between July 2018 and current models, supporting all regional variants including those with left-hand drive configurations. Installation requires no specialized tools, with OEM-grade push rivets that maintain factory-secured retention force throughout the vehicle's operational lifecycle. Compatibility confirmed with both steel and aluminum suspension components, including models equipped with adaptive dampers and rear-wheel steering systems.
