ABSTRACT:
An intake manifold assembly (10) for use with an internal combustion engine. The manifold assembly (10) includes three main components, a cover (12), base (14) and runner beam (16). The cover (12) and base (14) mate to form cavity (18), encompassing a plenum area (54) upstream of variable runners (52) formed by runner beam (16) and the variable runners (52). Rotation of the runner beam (16) causes a change in the length and cross-sectional area of the variable intake runners (52), thus varying the tuning of the intake flow into the engine, to optimize the flow for various engine speeds.
