Charged Air Manifold Dodge Ram 3500 All 2004-2007 Stock intake manifolds have sharp bends and corners. As air flows around these corners, dead air zones are created. These dead air zones choke down the air and restrict airflow to your engine.aFes MDV technology uses smooth bends and directional vanes to form multiple air paths through the manifold. These new paths are smoother and shorter, producing much smaller dead air zones for increased overall airflow to the engine. Unique airflow path with MDV Technology Proprietary internal bolt design guaranteed to not deform and leak Cast A356-T6 aluminum construction Up to five port pads Custom black-zinc finished steel bracket of OE wire harness Faster turbo spool-up More horsepower Increased low-end torque for more towing power Improved boost pressure Stainless steel hardware Charged Air Manifold
