Edelbrock 2519 - Marine Performer RPM Intake Manifold, Chevrolet 4.3 V6, Vortec 96-up

The Performer Vortec is a dual-plane design that is tuned for maximum airflow from idle to 5500 rpm. Designed specifically for use on 1996-present Chevy 4.3L V6 Vortec engines in a marine application. One of the unique features is the brass-lined water crossover and inserts to help protect the aluminum from salt-water corrosion and eliminate electrolysis in freshwater applications. It also features a carburetor flange that readily accepts square-bore and spread-bore carburetors. The Performer Vortec V6 Marine intake manifold is engineered to deliver maximum power and a broad torque curve for high-performance marine applications. Similar to the stock intake manifold, it includes a provision for 1/2 pipe water fittings on the front water crossover and 3/8 pipe horizontal vacuum fittings in the rear. Does not have a provision for an exhaust crossover, so an electric choke is required. Intended for marine use only and is not for street applications.
