ABSTRACT:
An air intake system for an internal combustion engine includes a manifold defining a chamber in which air is distributed to a plurality of engine cylinders. The chamber includes an inlet and a plurality of outlets, each outlet providing fluid communication between the chamber and an engine cylinder. Each of the plurality of outlets is substantially the same distance from the inlet to provide more consistent gas flow rates through the outlets. The air intake system preferably includes a plurality of runners. Each of the plurality of runners defines a passageway that interconnects one of the outlets to a respective engine cylinder. Each passageway is characterized by the same length and the same cross sectional area.
