51117374205 Cover | Front Bumper Lower Grille Closure Assembly

51117374205 Cover - Precision Grille Closure Solution

Designed specifically for BMW X1 F48/F49 models, the 51117374205 Cover provides a seamless closure for the front bumper lower grille opening. This essential component creates a clean, aerodynamic profile while protecting critical engine components from road debris and environmental elements. Manufactured from UV-stabilized ABS plastic through injection molding processes, the cover maintains dimensional stability across temperature extremes from -30°C to +85°C. The 51117374205 Cover features precisely engineered mounting clips that engage with factory mounting points without requiring modifications or special tools. Its matte black finish matches OEM specifications with 98% color accuracy and maintains consistent appearance without fading or discoloration. The integrated reinforcement ribs provide structural rigidity while minimizing weight, and the contoured design optimizes airflow management to balance cooling requirements with aerodynamic efficiency. Each unit undergoes dimensional verification to ensure ±0.5mm tolerance across all critical interfaces for perfect alignment with adjacent trim components.

Vehicle Compatibility Information

The 51117374205 Cover and its complementary component 51117374206 are engineered for BMW X1 F48 (standard wheelbase) and F49 (China long-wheelbase) Sports Activity Vehicles. This pair of grille closure covers is validated for 2016-2022 model years across all trim levels including sDrive18i, sDrive18d, sDrive20i, xDrive20i, xDrive25i and xDrive25d variants. Compatible with both standard and M Sport package configurations, these covers directly replace original components referenced under part numbers 51-11-7-374-205 and 51-11-7-374-206. The design accommodates all factory lighting configurations including halogen and LED fog light assemblies. Installation requires no modification for vehicles with or without front parking sensors, and maintains proper clearance for tow hook access. Before purchase, verify your vehicle's production date and confirm compatibility with BMW X1 F48/F49 platform.

Engineering Specifications

Constructed from high-impact ABS plastic with 15% glass fiber reinforcement, the 51117374205 Cover achieves optimal balance between structural integrity and weight efficiency. The manufacturing process utilizes temperature-controlled molds maintained at 75±5°C for consistent surface texture and dimensional accuracy. Aerodynamic profiling reduces wind turbulence by 22% compared to open grille configurations while maintaining proper airflow to critical components. UV-resistant formulation incorporates carbon black stabilizers that maintain 97% color retention after 5 years of sun exposure. Mounting clips feature glass-filled nylon construction with engineered flex points rated for 10,000+ installation cycles. The honeycomb reinforcement pattern increases impact resistance by 40% while reducing weight by 15% compared to solid designs. All edges feature radiused contours to prevent paint abrasion during installation, and the matte texture finish resists fingerprint marks and maintains consistent appearance across temperature variations.

Compatibility Assurance

Compatible with 2016-2022 BMW X1 F48 and F49 platform Sports Activity Vehicles. This product is designed to match functional and dimensional characteristics of original components for specified applications.
