This single-plane intake manifold is designed to keep your air and fuel distribution going into the engine at a steady and even flow for maximum performance and efficiency. The carburettor-mounting pad is designed to accept aftermarket 4150 square-bore throttle bodies or adapter plates for turbocharged applications. Specifically designed to suit GM LS Gen III and IV engines equipped with OE or aftermarket LS3 rectangle port cylinder heads.
