Abstract:
A method for assembling an intake manifold for an engine having a plurality of cylinders, comprising the steps of:providing an intake manifold having an air inlet, a central plenum disposed between a pair of side plenums, where air enters the manifold in proximity to the central plenum and is distributed to the side plenums, long runners for conducting air from the side plenums to the cylinders, short runners for conducting air from the central plenum to the cylinders, wherein the short runners are arranged generally longitudinally along the intake manifold and define at least one longitudinally outer short runner and at least a middle short runner inboard from said outer short runner;providing a valve shaft;providing a valve for each short runner to define outer and middle short runner valves corresponding to the respective outer and middle short runners;positioning said at least one outer valve in the respective short runner to set a gap between the valve and the respective short runner;attaching the said at least one outer valve to the valve shaft;positioning said at least one middle valve in the respective short runner to set an endplay for the valve shaft; andattaching said at least one middle valve to the valve shaft.
