51117159595 Lower Grilles | Aerodynamic Open-Grille System
51117159595 Lower Grille: Precision Bumper Integration
Engineered for seamless compatibility, the 51117159595 Lower Grille delivers OEM-grade fitment through injection-molded ABS construction with UV-resistant additives. The black matte finish employs multi-layer polymer coating that resists stone chips and environmental degradation. Precision-engineered mounting tabs maintain 0.5mm positional accuracy for vibration-free installation across temperature extremes (-30°C to 80°C). Aerodynamic vanes reduce turbulence while protecting radiator components from debris intrusion. The open grid pattern optimizes airflow to engine cooling systems without compromising structural rigidity. Integrated clip receptors feature stainless steel reinforcement for consistent retention force matching factory specifications. Surface texturing replicates original BMW components' matte finish while improving scratch resistance. Pre-installed alignment guides ensure symmetrical positioning with adjacent body panels. The dual-pack configuration provides complete left/right bumper coverage with identical material properties and color consistency across both grilles.
Technical Specifications of 51117159595 Lower Grille
Material Engineering
Utilizes glass-fiber reinforced ABS composite with 15% mineral additives for enhanced dimensional stability. The material formulation achieves 65 MPa tensile strength while maintaining 3.5% elongation at break for impact absorption. Surface treatment includes corona discharge processing to improve paint adhesion consistency. UV inhibitors are compounded directly into the polymer matrix rather than surface-coated, ensuring 10+ years of color retention. Internal rib structures increase rigidity by 40% compared to standard ABS while maintaining weight parity with OEM components. The material meets GMW3052 flammability standards and demonstrates less than 0.8% moisture absorption in humidity cycling tests.
Design Features
Maintains original equipment airflow rates of 650 CFM ±5% at highway speeds through computational fluid dynamics-optimized grid geometry. Clip retention force calibrated to 12-18N range using stainless steel inserts that prevent plastic deformation over repeated thermal cycles. Symmetrical mounting points allow 360° rotational adjustment during installation for perfect panel alignment. Pre-molded service channels permit access to fog light assemblies without grille removal. The honeycomb pattern density varies across the surface to balance structural integrity and airflow requirements. Backside reinforcement ribs follow original BMW tooling patterns to maintain crash compatibility with pedestrian protection systems.
Vehicle Compatibility Details
Specifically developed for pre-LCI BMW X5 E70 models produced between Q3 2006 and Q2 2010. Confirmed fitment for vehicles with both standard and M Sport bumper configurations. Compatible with factory-installed parking sensors, headlight washers, and auxiliary lighting systems. Not suitable for models equipped with night vision cameras or aftermarket bumper extenders. For vehicles with Active Cruise Control, verify sensor clearance requirements before installation. Some late-model 2010 vehicles may require confirmation of bumper support bracket configuration. Always cross-reference using original vehicle production date and VIN decoder to ensure compatibility. The left-side grille (51117159595) and right-side grille (51117159596) must be installed as a pair to maintain aerodynamic balance and visual symmetry.
