51117331671 Fog Grill | Structural & Aesthetic Compliance

Designed for 2010-2017 BMW 5 Series Gran Turismo models, the 51117331671 Fog Grill system employs reinforced ABS composite with UV-stable texture matching OEM specifications. The hexagonal ventilation pattern enhances airflow dynamics by 33% while filtering particles above 5mm. Precision-engineered clip receptors maintain ±0.3mm alignment accuracy across standard and M Sport bumper variants.

Multi-layer surface treatment combines texture replication with hydrophobic coating to minimize water retention. Modular construction enables direct replacement of damaged components without bumper disassembly. Integrated drainage channels prevent moisture accumulation while maintaining structural rigidity across temperature extremes (-30°C to 110°C).
