51119498612 Shutter | Front Bumper Radiator Grill Assembly

The 51119498612 Shutter provides critical airflow management for front bumper radiator assemblies in 2021-2022 BMW G38 LCI and 2020-2023 G30/G31 models. This precision-engineered radiator grille shutter optimizes engine cooling efficiency while protecting vital components from road debris and environmental contaminants. Designed specifically for non-motorized configurations, the shutter features aerodynamic vanes that dynamically regulate airflow based on driving conditions, reducing drag during highway cruising for improved fuel efficiency while ensuring maximum cooling capacity during demanding operation. The component's open-mesh construction balances debris protection with unrestricted airflow, maintaining optimal engine temperatures under varying driving conditions without electronic activation requirements.

Manufactured using glass-reinforced polyamide composite materials, the shutter withstands extreme temperature fluctuations from -40°C to 120°C while resisting degradation from UV exposure and road chemicals. Structural reinforcements at mounting points ensure vibration resistance and long-term dimensional stability. The design precisely replicates OEM contours with integrated mounting tabs that align with factory attachment locations for tool-free installation. Aesthetic considerations include surface textures that match surrounding trim components and blackout finishes that maintain the vehicle's sophisticated appearance. The shutter's aerodynamic profile reduces turbulence around front sensors while providing impact protection for radiator cores and condenser units from stone chips and minor impacts without compromising the BMW's signature front-end styling.
