51117954251 Grille | BMW F49 X1 LCI Fog Lamp Frame Grille System

51117954251 Grille - Precision Fog Lamp Frame for BMW F49 X1 LCI Models

Specifically engineered for BMW X1 F48/F49 LCI variants, the 51117954251 Grille provides structural reinforcement and aerodynamic optimization for front bumper fog lamp assemblies. This bright black ABS component features precision-engineered ventilation holes that maintain proper airflow to lamp units while preventing debris ingress. The injection-molded construction ensures 0.2mm dimensional accuracy to factory specifications, with UV-stabilized polymer formulation resisting color fade under prolonged sun exposure. Integrated mounting points align with both standard and M Sport bumper configurations, utilizing stainless steel clips for vibration-resistant retention. Surface texture replicates OEM matte-black finish, requiring no additional treatment beyond standard cleaning procedures. Installation involves direct replacement of existing grilles through clip engagement without requiring bumper removal.

OEM-equivalent fitment for LCI bumper profiles

Anti-fingerprint matte black surface finish

Optimized airflow through geometric vent design

Manufacturing Specifications and Performance Features

The 51117954251 Grille employs advanced polymer engineering with 30% glass fiber reinforcement in critical stress areas. The honeycomb ventilation pattern maintains 62% open area ratio for optimal lamp cooling while blocking road debris larger than 6mm. Molded-in mounting tabs feature stainless steel reinforcement cores that withstand 25N of direct impact force without deformation. Surface treatment utilizes two-stage texturing process that creates fingerprint-resistant matte finish while maintaining impact resilience. All edges incorporate 0.8mm radius beveling to prevent paint damage during installation. The component withstands continuous operating temperatures from -30°C to 85°C without warping or loss of structural integrity. Backside ribs maintain 1.5mm wall thickness for weight optimization while ensuring dimensional stability across bumper curvature variations.
