51137349592 Fender Vents | Aerodynamic Airflow Compliance

Designed exclusively for 2018-2019 BMW 5 Series G30/G38 models, the 51137349592 Fender Vents feature optimized aerodynamic geometry that reduces turbulent airflow around front wheel arches. The precision-molded components integrate seamlessly with factory body contours using advanced polypropylene composite material for exceptional UV resistance and impact durability. Integrated mounting points align with OEM attachment locations for perfect fitment without modification. The directional vanes accelerate air extraction from wheel wells, reducing lift forces at high speeds while preventing debris accumulation.

Computational fluid dynamics analysis informs the precisely angled louvers that optimize pressure differentials between wheel arch and exterior surfaces. The hydrophobic surface treatment repels water and road contaminants while maintaining OEM-matched texture depth. Installation requires no specialized tools thanks to integrated alignment guides and factory-specification mounting hardware. Thermal-stabilized formulation ensures dimensional integrity across -40°C to 120°C operating conditions while reducing aerodynamic drag coefficient during highway driving.
