51647200689 Radiator Cover | Front Upper Sight Shield Assembly

The 51647200689 Radiator Cover delivers precision-engineered protection for BMW 5-Series models (2011-2016). This aluminum upper sight shield features aerospace-grade T6 temper treatment, providing exceptional heat dissipation while maintaining structural integrity under hood temperatures up to 400°F. Its smooth black anodized finish resists corrosion from road salts and brake dust accumulation.

Designed as a direct factory-style replacement, it integrates seamlessly with both standard and M Sport front fascias. The contoured profile directs airflow efficiently across radiator surfaces, while laser-etched alignment markers ensure perfect positioning relative to headlight clusters. All mounting points mirror OEM specifications for tool-free installation across sedan and hatchback variants.
