51117331770 Fog Light Trim | Aerodynamic & Aesthetic Enhancement

The 51117331770 Fog Light Trim combines injection-molded ABS-PC composite with chrome-plated stainless steel inserts, engineered for precise alignment with F10/F11 fog lamp apertures. Its dual-layer UV-resistant coating maintains 92% reflectivity after 5,000 hours of accelerated weathering tests. The interlocking clip design ensures 0.8mm panel gap consistency across temperature fluctuations from -30°C to 85°C.

Precision-molded drainage channels prevent water ingress behind headlight assemblies, while the reinforced mounting points withstand 35N pull-out force. The contour-matched profile reduces aerodynamic turbulence by 22% compared to standard replacements. Pre-installed vibration dampeners maintain 0.5mm clearance tolerance during suspension articulation.
