Patent ID: 7107958

Claim:
A tunable intake manifold for directing a flow of air to an internal combustion engine, said tunable intake manifold comprising: a manifold housing defining an interior extending between a receiving end and a transmitting end, said manifold housing having a runner wall extending through said interior; a plenum coupled to said receiving end of said manifold housing and having an inner cavity in fluid communication with said interior of said manifold housing; a slider having a slider wall extending through said interior of said manifold housing, said slider wall cooperates with said runner wall to define a runner having a defined cross sectional area for transporting the flow of air therethrough, said slider slidably engaged with said manifold housing for moving said slider wall relative to said runner wall to selectively change said defined cross sectional area of said runner, such that the volume of air passing therethrough changes with said movement of said slider; and a conduit extending between said housing and said plenum for transporting a secondary flow of air to said runner with said selective change of said cross sectional area of said runner by said movement of said slider wall.
