51117331767 Grille Trim | Aerodynamic & Aesthetic Integration

The 51117331767 Grille Trim utilizes injection-molded ABS+PC composite with vapor-deposited chrome finish, maintaining 0.15mm dimensional accuracy for Modern Line bumper integration. Its three-stage surface treatment achieves 90GU gloss retention after 3-year UV exposure, matching factory-level light refraction characteristics. The interlocking tab system provides ±1.2mm thermal expansion compensation across -40°C to 110°C operating range.

Aerodynamically optimized vanes reduce front-end lift by 14% at 75mph compared to aftermarket alternatives. The dual-density mounting bushings absorb 85% of road vibration energy while maintaining 0.4mm panel gap consistency. Pre-molded alignment channels ensure precise sensor housing clearance for ActiveHybrid 5 models' collision avoidance systems.
