51647326554 Air Deflector: Aerodynamic Component for BMW F15 X5 & F16 X6
Engineered specifically for 2014-2018 BMW F15 X5 and F16 X6 models, the 51647326554 Air Deflector optimizes radiator airflow management while protecting critical engine components from road debris impacts. This aerodynamic component directs cooling air efficiently through radiator fins during highway operation. Flexible thermoplastic construction withstands repeated vibration cycles without cracking. Integrated mounting clips ensure secure attachment without fastener loosening. Road-spray resistant material prevents water absorption in wet conditions. Contoured design minimizes aerodynamic drag at higher vehicle speeds. Precision-molded channels divert debris away from radiator surfaces. Impact-modified material properties resist stone chip damage effectively. Temperature-stable polymers maintain dimensional accuracy in extreme climates. UV-inhibited formulation prevents surface degradation from prolonged sun exposure. Engineered airflow channels reduce turbulence for optimized cooling efficiency. Precisely positioned mounting tabs maintain factory-specified alignment tolerances.
Optimized for full model year range compatibility 2014-2018. Includes all required attachment hardware for direct installation.



Technical Specifications: 51647326554 Air Deflector
Material Engineering
High-impact copolymer withstands repeated debris strikes without fracture. UV-stabilized formulation prevents material degradation from sunlight exposure. Hydrolysis-resistant polymers prevent moisture absorption in humid environments. Flexible elastomer-modified blend absorbs road vibration energy. Temperature-resistant composition maintains rigidity from -40°F to 240°F. Anti-static additives prevent dust accumulation on critical surfaces. Color-stable pigments maintain appearance throughout product lifespan. Fiber-reinforced sections enhance structural integrity at mounting points. Micro-ribbed underside reduces harmonic vibration at highway speeds. Chemical-resistant surface prevents damage from road treatment fluids. Molded-in attachment points eliminate secondary fastener requirements. Precision injection molding ensures dimensional accuracy to thousandths of an inch. Accelerated weathering testing validates long-term durability under extreme conditions.
Aerodynamic Design
Computational fluid dynamics optimize airflow to radiator surfaces. Directional vanes channel cooling air efficiently through condenser fins. Boundary layer management reduces aerodynamic drag at speed. Turbulence-reducing contours smooth underhood airflow patterns. Venturi-designed channels accelerate air velocity across heat exchangers. Debris-deflection geometry protects radiator fins from stone damage. Water-shedding surface texture prevents moisture accumulation. Pressure-equalizing vents maintain balanced airflow distribution. Speed-compensated design adjusts airflow characteristics with velocity. Underbody air management reduces front-end lift at higher speeds. Road-spray deflection shields prevent water intrusion into electrical components. Air curtain generation creates protective barrier around suspension components. Heat-shield properties prevent radiant thermal transfer to nearby parts.
Compatibility Information
Exclusively compatible with 2014-2018 BMW F15 X5 and F16 X6 models requiring front radiator air management components. Direct replacement for original air deflectors damaged by impacts or weathering. Fits both gasoline (35i, 40i, 50i) and diesel (25d, 30d, 50d) powertrain configurations. Compatible with all-wheel drive (xDrive) and rear-wheel drive (sDrive) models. Early production 2014 models require verification of manufacturing date. Late 2018 models may have revised mounting points requiring inspection. Maintains proper clearance with factory-installed auxiliary coolers and oil coolers. Fits both standard and M Sport bumper configurations without modification. Models with adaptive cruise control require sensor area clearance verification. X5 xDrive40e plug-in hybrid models utilize identical air deflector design. Vehicles manufactured prior to 01/2014 or after 12/2018 require alternative components.
