51113420091 Grille: Aerodynamic Enhancement for BMW E83 LCI Models
The 51113420091 Grille delivers factory-correct styling and airflow management for the front fascia of BMW E83 LCI vehicles. Engineered with pressure-formed graphite metallic coating, this component maintains BMW's signature aesthetic while optimizing cooling system airflow. The 51113420091 Grille features precisely calculated aperture spacing that balances radiator airflow with debris deflection. High-density ABS core provides structural rigidity while maintaining weight efficiency, with UV-resistant surface treatment that preserves color depth through extreme weather cycles.
Integrated mounting tabs replicate original equipment geometry for vibration-free installation. Precision contouring matches factory body lines within ±0.5mm tolerance, ensuring seamless visual integration with headlight clusters and bumper covers. The aerodynamic profile reduces turbulent air entry while maintaining BMW's characteristic kidney grille proportions. Surface texturing matches OEM specifications to maintain light diffusion characteristics, preventing unwanted reflections during night driving. Pre-installed vibration dampeners ensure silent operation across all speed ranges.

Engineering Specifications
Material Composition
High-impact ABS substrate with multilayer metallic coating. UV-stable polymer matrix resorts color fading. Flexible edge seals compensate for thermal expansion without compromising fitment.
Aerodynamic Design
Computational fluid dynamics-optimized vanes direct airflow to radiator core. Vortex-reducing edges minimize wind noise above 50 mph. Pressure-equalizing channels prevent harmonic vibration.
Surface Durability
5-stage electrostatic painting process ensures uniform metallic finish. Chemical-resistant clear coat withstands road salts and cleaning agents. Micro-textured surface hides minor abrasions.
Installation Precision
Pre-molded alignment guides ensure perfect positioning. Tool-free mounting system maintains factory clip engagement force. Integrated dust seals prevent debris accumulation behind grille.
Model-Specific Integration
The 51113420091 Grille is engineered for precise fitment on BMW E83 X3 LCI models produced between 2007-2010. Direct replacement for original front left (nearside) grille assemblies on both standard and M-Sport bumper configurations. Maintains proper clearance for auxiliary lighting systems and parking sensors where factory-equipped.
Mounting system accommodates all factory fastener types used during production period. Profile matches revised LCI bumper contours exactly, ensuring proper integration with updated headlight designs. Color-matched graphite metallic finish aligns with BMW paint code specifications for period-correct appearance. Installation requires no modification to surrounding components or bumper structure.
Compatible with: 2007-2010 BMW E83 X3 LCI models requiring front left nearside grille components identified by part numbers 51113420091 or 51 11 3 420 091
