Proline Oval Louver

The Vintage Air Proline Oval Louver (Part No. 491902) is a precision-engineered in-dash air conditioning outlet designed for classic and custom vehicles requiring OEM-quality climate control integration. This component serves as the visible distributor that channels cooled or heated air into the cabin, making it essential for both performance and visual appeal in restomod builds where stock air vents either don't exist or require replacement.

Built by Vintage Air—the industry standard for retrofit climate systems—this oval louver features precision-molded construction optimized to minimize turbulence while maximizing volumetric airflow delivery. The compact face profile of 2.95 x 2.5 inches fits seamlessly into tight dash spaces typical of 1950s–1970s vehicles, while the overall depth accommodates the necessary ductwork and mounting hardware for secure installation. The 0.44 lb weight ensures it won't stress mounting tabs, and the design allows for full directional adjustment so you can aim air exactly where occupants need it.

This louver is ideal for builders installing Vintage Air's modular climate systems into hot rods, street rods, and restomod trucks where maintaining a classic aesthetic is crucial. Its design is particularly beneficial in custom interiors where seat positioning doesn't always align with factory vent geometry, ensuring that all occupants enjoy optimal comfort.
