Proline Oval Louver

The Vintage Air Proline Oval Louver (Part No. 491902) is an in-dash heating and cooling louver designed for custom automotive climate control installations. This oval-shaped louver accepts 2.5-inch diameter hose connections and delivers conditioned air directly into the cabin with precise directional control. Built from durable plastic construction with chrome finish accents, this louver is engineered for vehicles where factory HVAC integration is not possible or where modern climate systems are being retrofitted into classic or custom builds.

The louver features a compact 4 x 1.600-inch mounting footprint and weighs only 0.44 lbs, making it suitable for tight dashboard spaces without adding significant weight to the vehicle. The oval design distributes airflow efficiently across a wider area than traditional round louvered vents, reducing turbulence and improving thermal comfort. The 2.5-inch hose compatibility aligns with standard Vintage Air system tubing, ensuring seamless integration into existing Proline climate control packages. Mounting is straightforward, requiring minimal dash modification while maintaining professional appearance and functionality.

This louver is ideal for restoration shops, custom builders, and hot rod enthusiasts installing modern heating and cooling systems into classic vehicles where original HVAC components are unavailable or incompatible. It serves both heating and cooling applications, making it versatile for year-round climate management in custom builds. The chrome-accented finish coordinates with classic and modern interior trim styles, allowing builders to maintain aesthetic consistency while upgrading comfort technology. Proline louvered vents are recognized components in the custom automotive aftermarket, trusted by shops specializing in classic car restoration and performance vehicle builds.
