40mm IDF Carburetor Kit with Air Filter

The Webber/EMPI 43-7315 is a single 40mm IDF carburetor kit designed to enhance the performance of air-cooled Volkswagen dual-port upright engines. This kit features a genuine Weber carburetor paired with an EMPI intake manifold, delivering a precise fuel and air mixture for increased horsepower and improved throttle response. It is suitable for both street and off-road applications and comes with all necessary components for installation, including an aluminum/steel center-section manifold, aircraft-style heim joint linkage, a chrome air cleaner with a gauze element, gaskets, hardware, and illustrated instructions. The product is explicitly noted as being for off-road use only and is not CARB certified, meaning its use on public roadways may be illegal in certain states with strict emissions regulations. Application information provided is for reference and may not apply to stock vehicle configurations; users are advised to verify their specific application before purchase. While considered a universal part adaptable to various applications with modifications, the kit specifies compatibility with VW Bug (1949-1977), Super Beetle (1971-1979), Ghia (1955-1974), Bus (1950-1971), and Thing (1973-1974) models. The carburetor itself offers tunable performance with removable jets, emulsion tubes, and venturis, allowing for precise engine tuning with adjustable idle and main circuits, as well as an adjustable accelerator pump.
