51117171345 Lower Grille: Precision Front Bumper Component

Engineered for direct replacement applications, the 51117171345 Lower Grille integrates seamlessly into BMW E70 X5 front bumper assemblies from 2007 to 2009 model years. This injection-molded ABS component maintains original equipment dimensional specifications with precision tolerances under 0.5mm across its 835mm length. The textured matte black finish ensures consistent appearance while resisting UV degradation and environmental contaminants. Integrally molded mounting points align with factory bumper receptacles for tool-free installation without modification requirements. Structural reinforcement ribs maintain dimensional stability across thermal cycling conditions while accommodating airflow management requirements. Integrated mounting clips provide secure retention with stainless steel hardware rated for repeated service cycles. The open-grid design optimizes radiator airflow while preventing debris intrusion without compromising the vehicle's aerodynamic profile.

Technical Specifications of 51117171345 Lower Grille

Material Engineering

Manufactured from high-impact ABS polymer blended with UV stabilizers meeting ISO 4892-2 accelerated weathering standards. Material formulation achieves optimal balance between impact resistance (6.2 kJ/m² Charpy rating) and thermal stability across -30°C to 80°C operating range. Injection molding process ensures uniform wall thickness of 3.2±0.3mm throughout the component. Integrated color pigments provide consistent matte black appearance without requiring secondary painting processes. The polymer matrix incorporates anti-static additives to minimize dust accumulation while maintaining surface appearance. Material selection undergoes rigorous verification for compatibility with automotive chemicals including road salts, fuels, and cleaning agents.

Design Integration

Features precision-engineered contours matching factory bumper profiles with 0.8mm maximum deviation tolerance. The geometric lattice structure provides 32.5% open area for optimized airflow to cooling systems while blocking road debris. Integrated mounting clips utilize stainless steel springs maintaining 45N retention force throughout service life. Sixteen strategically positioned attachment points distribute load evenly across bumper substructure. Internal reinforcement ribs increase rigidity by 40% compared to conventional designs without adding weight. The component accommodates factory-installed parking sensors and tow hook covers without interference. Aerodynamic validation confirms drag coefficient alignment with original equipment specifications at highway speeds.

Compatibility Details

Specifically engineered for 2007-2009 BMW E70 X5 models with standard front bumper configurations. Direct replacement compatibility confirmed for both pre-facelift models and vehicles with Sport Package trim. Verified fitment across all drivetrain variants including xDrive30i, xDrive35i, xDrive48i, and xDrive35d powertrains. Accommodates factory fog light assemblies and headlight washer systems without modification requirements. Not compatible with models equipped with Active Steering or Night Vision systems requiring additional front-end components. For vehicles manufactured after March 2009, confirm bumper design compatibility as facelift models incorporate revised mounting points. Always verify factory part number against vehicle production date to ensure proper fitment with existing bumper assembly components and radiator support structures.
