Patent ID: 8191525

Claim:
An engine intake manifold, comprising: a first port located in said intake manifold and in an air flow path downstream of a throttle body mounting flange and upstream of a plurality of runners; and a protrusion from an inside wall of said intake manifold, a length of said protrusion less than a diameter of said intake manifold where said protrusion is located, said protrusion located downstream of said first port and upstream of said plurality of runners, where said protrusion is in a roof of said intake manifold and said runners are intake runners, where the first port opens through the inside wall of the intake manifold, and further comprising an intake manifold inlet formed by the throttle body mounting flange, where said protrusion is oblong and where a long side of said protrusion is perpendicular to a flow of gases from said first port, and further comprising anti-whoosh vanes spaced away from the protrusion, where a first group of anti-whoosh vanes are on an opposite side of the intake manifold inlet as the first port, and where the first port is positioned between a second group of anti-whoosh vanes and the protrusion.
