Abstract
The present invention relates to an intake manifold including first and second plenums in fluid communication with the throttle body and a plurality of runners depending from the plenums to direct air into the cylinders of an engine. Each of the runners includes a vent to release pressurized air within the runner. The intake manifold tuning assembly further includes a tuning device disposed between the plenums, the tuning device includes a housing having a plurality of tuning ports aligned relative to the vents to receive pressurized air from the runners. An intermediate plenum is defined within the housing that directs pressurized air from one runner to another runner corresponding to the next cylinder in the firing sequence of the engine. Valves regulate the transfer of pressurized air between the runners for increased torque output over a predetermined range of engine speed.
