Twin-Ram 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. Twin-Ram 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. By driving a greater charge of air into each chamber, Twin-Ram amps up the power rating, improves mileage and durability, and reduces emissions. Key Features: Enhances power, mileage and durability. Larger & less restrictive than stock. Provides tremendous flow and uniform air distribution. Cast intake manifold design doubles stock inlet area. Increases and balances boost-air distribution into all six cylinders. Eliminates internal hot spots. Reduces emissions. Dodge 5.9L, Non-EGR. 5-year Warranty.
