51117135573 Grille | Front Bumper Central Ventilation Assembly

Precision-engineered for BMW's flagship luxury sedan, the 51117135573 Grille delivers both functional airflow management and distinctive aesthetic enhancement to the vehicle's front fascia. Manufactured from automotive-grade ABS plastic with reinforced polymer matrix, this center bumper grille withstands road debris impacts while maintaining dimensional stability across temperature extremes from -30°F to 180°F. The optimized ventilation pattern balances aerodynamic efficiency with maximum cooling airflow to critical engine components, featuring precisely angled vanes that reduce drag while deflecting water and particulate matter.

The 51117135573 Grille features E66 LCI-specific curvature that seamlessly integrates with factory bumper contours. Its primed surface finish provides ideal adhesion for color-matching paint applications while specialized texture replication ensures visual consistency with surrounding components. Integrated mounting points feature self-aligning guides that simplify installation while maintaining precise panel gaps. Each unit undergoes dimensional validation against original specifications to guarantee perfect fitment with bumper reinforcement structures and adjacent trim pieces. The reinforced perimeter frame distributes impact forces while maintaining the grille's structural integrity through years of service.
