51747343805 Duct | Track-Optimized Brake Cooling for BMW M-Series (2015-2020)
51747343805 Duct | Track-Optimized Brake Cooling for BMW M-Series (2015-2020)
51747343805 Duct: BMW Brake Cooling Air Channel System
Engineered for high-performance BMW models, the 51747343805 brake cooling duct optimizes airflow to critical braking components. This precisely molded 51747343805 Duct directs ambient air through strategic channels to reduce brake system temperatures during aggressive driving. Constructed from heat-resistant polymer compounds, the duct maintains structural integrity in extreme thermal conditions while resisting degradation from road chemicals and moisture. The aerodynamic profile integrates with factory bumper openings to capture high-pressure airflow at speed, funneling cooling currents directly to brake rotor assemblies. Installation requires no modifications to existing body panels, utilizing original mounting points and fastener locations for perfect OEM-style fitment.
Internal guide vanes within the duct structure accelerate airflow velocity by 40% compared to open-channel designs, ensuring efficient heat dissipation during track use or mountain driving. The component's smooth interior surface minimizes turbulent airflow while preventing debris accumulation. Reinforced mounting flanges withstand vibration stresses from both engine operation and road surface impacts. UV-stabilized material formulation prevents embrittlement and color fading, maintaining reliable performance across seasonal temperature extremes from -30°C to 120°C. The duct's angled intake opening aligns with BMW's factory aerodynamic profile, preserving the vehicle's drag coefficient while enhancing brake cooling capacity.
Precision Vehicle Fitment
The 51747343805 cooling duct maintains exact factory specifications for BMW M-performance models and sport package variants. Designed specifically for left-side installation, this component complements BMW's asymmetric brake cooling system architecture. Compatibility extends to vehicles equipped with both standard and ceramic composite braking systems.

Direct replacement for vehicles originally equipped with brake cooling duct reference 51747343805.
Engineering Specifications
Thermal Management
High-temperature nylon composite withstands repeated thermal cycling without deformation. Internal airflow accelerators create venturi effects for targeted brake component cooling. Heat-deflective surface coating radiates 30% more thermal energy than standard components.
Structural Design
Precision-molded contours match factory bumper profiles within 0.5mm tolerance. Reinforced mounting tabs distribute mechanical stresses across multiple anchor points. Flexible edge seals prevent air leakage while accommodating bumper flex during suspension articulation.
Performance Features
Aerodynamically optimized inlet scoop captures high-pressure airflow at speed. Directional internal vanes maintain laminar flow to brake rotors. Integrated debris screens prevent stone ingress without restricting airflow. Maintenance-free design requires no lubrication or adjustments.
