Abstract
A tunable intake manifold is provided for directing a flow of air between a plenum and an internal combustion engine. The tunable intake manifold includes a manifold housing defining an interior. The manifold housing has a plurality of runner walls extending through the interior. The tunable intake manifold also includes a slider having a slider wall having an angled portion separated from a primary portion by a curved portion. The slider wall extends through the interior of the manifold housing. The slider wall cooperates with the runner wall to define a runner having a defined cross sectional area for transporting the flow of air therethrough. The slider is slidably engaged with the manifold housing for moving the slider wall relative to the runner wall to selectively change the defined cross sectional area of the runner, such that the volume of air passing therethrough changes with the movement of the slider. The angled portion of the slider travels parallel to the runner wall at a transmitting end of the runner.
