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. aFe's 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 PartNumber : afe46-90087 Description : BladeRunner EGR Cooler; OE Replacement; 2004 Ford F-250 Super Duty Harley-Davidson Edition V8.-cc Uncategorized::Uncategorized 2004 Ford F-250 Super Duty King Ranch V8.-cc Uncategorized::Uncategorized 2003-2004 Ford F-250 Super Duty Lariat V8.-cc Uncategorized::Uncategorized 2003-2004 Ford F-250 Super Duty XL V8.-cc Uncategorized::Uncategorized 2003-2004 Ford F-250 Super Duty XLT V8.-cc Uncategorized::Uncategorized 2004 Ford F-350 Super Duty Harley-Davidson Edition V8.-cc Uncategorized::Uncategorized 2003-2004 Ford F-350 Super Duty King Ranch V8.-cc Uncategorized::Uncategorized 2003-2004 Ford F-350 Super Duty Lariat V8.-cc Uncategorized::Uncategorized 2003-2004 Ford F-350 Super Duty XL V8.-cc Uncategorized::Uncategorized 2003-2004 Ford F-350 Super Duty XLT V8.-cc Uncategorized::Uncategorized
