51117417784 Front Grille | Bilateral Front Assembly Components

The 51117417784 Front Grille utilizes high-impact ABS polymer with vacuum-metallized chrome plating, maintaining 0.8mm blade spacing accuracy across 15 vertical slats. Its dual-material construction combines glass-fiber reinforced framework with flexible mounting tabs, ensuring ±0.4mm dimensional tolerance across temperature fluctuations from -30°C to 80°C. The interlocking design features 12 corrosion-resistant brass threaded inserts that prevent harmonic resonance at highway speeds.

Surface treatment incorporates 8-stage polishing followed by nano-ceramic coating achieving 92GU gloss rating. The aerodynamic contour reduces air turbulence by 18% compared to standard aftermarket alternatives, while maintaining factory-spec sensor cutouts for parking assistance systems. Compatible with both standard and M Sport bumper configurations without modification.
