Abstract
A tunable intake manifold extends between a plenum and an intake of an internal combustion engine. A manifold housing defines an interior and a runner wall extending through the interior. A slider extends through the interior and slidably engages the manifold housing. The slider defines a slider wall cooperative with the runner wall to form a runner for transporting air therethrough. The runner defines a cross section. A drive assembly is operatively coupled between the manifold housing and the slider to move the slider transversely along the manifold housing to change the defined cross section of the runner such that the volume of air passing therethrough changes with the movement of the slider.
