The Hellmann Billet Intake Manifold is the original one-piece side draft intake manifold. The innovative design was initially created to solve the issues stemming from porting and polishing process on the intake side of the cylinder head. To properly perform this function, the cast manifold must be cut off of the cylinder head, leaving no way to secure fuel components and intake piping. The Hellmann Performance Billet Intake Manifold will secure to the side of the cylinder head taking the place of the preformed restrictive cast piece. The Manifold is designed with performance in mind; enlarged intake entrance ports are much less restrictive than stock creating superior air flow. Hellmann Performance’s Billet Intake Manifold is constructed from a single piece of aircraft grade T6 billet aluminum. It is cut to exacting specification in a state of the art CNC machine. The Manifold is predrilled for fuel rail installation, and comes with high grade stainless steel hardware. All predrilled mounting holes have been painstakingly measured to ensure perfect fitment of all OEM fuel components, including being able to accept dual CP3 injection pumps. The kit also comes with a prefabricated intercooler pipe, v-band clamp, and return line fittings. Manifolds are designed for 2003-present Dodge 5.9L and 6.7L Cummins Turbo Diesel engines.
