Banks Power Intake Manifold SystemTwinRam intake manifold doubles the inlet area, optimizes air distribution into the cylinder head, and flows the boosted air proportionately into all six cylinders. The equalized air streams do away with lopsided internal temperatures, balance cylinder air volume and produce smoother output. Optimizes Cylinder Air Distribution. Enhances power, mileage and durability. TwinRam intake manifold doubles the inlet area, optimizes air distribution into the
