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 : afe46-60039-1 Description : BladeRunner Turbo Inlet Manifold; Powdercoat Black; Multi-Directional Vane Technology; 2006 Chevrolet Silverado 2500 HD LS V8.6599cc Forced Induction::Turbo Kits 2006-2010 Chevrolet Silverado 2500 HD LT V8.6599cc Forced Induction::Turbo Kits 2007-2010 Chevrolet Silverado 2500 HD LTZ V8.6599cc Forced Induction::Turbo Kits 2006-2010 Chevrolet Silverado 2500 HD WT V8.6599cc Forced Induction::Turbo Kits 2006 Chevrolet Silverado 3500 LS V8.6599cc Forced Induction::Turbo Kits 2006 Chevrolet Silverado 3500 LT V8.6599cc Forced Induction::Turbo Kits 2006 Chevrolet Silverado 3500 WT V8.6599cc Forced Induction::Turbo Kits 2007-2010 Chevrolet Silverado 3500 HD LT V8.6599cc Forced Induction::Turbo Kits 2007-2010 Chevrolet Silverado 3500 HD LTZ V8.6599cc Forced Induction::Turbo Kits 2007-2010 Chevrolet Silverado 3500 HD WT V8.6599cc Forced Induction::Turbo Kits 2006 GMC Sierra 2500 HD SL V8.6599cc Forced Induction::Turbo Kits 2006-2010 GMC Sierra 2500 HD SLE V8.6599cc Forced Induction::Turbo Kits 2006-2010 GMC Sierra 2500 HD SLT V8.6599cc Forced Induction::Turbo Kits 2006-2010 GMC Sierra 2500 HD WT V8.6599cc Forced Induction::Turbo Kits 2006 GMC Sierra 3500 SL V8.6599cc Forced Induction::Turbo Kits 2006 GMC Sierra 3500 SLE V8.6599cc Forced Induction::Turbo Kits 2006 GMC Sierra 3500 SLT V8.6599cc Forced Induction::Turbo Kits 2006 GMC Sierra 3500 WT V8.6599cc Forced Induction::Turbo Kits 2007-2010 GMC Sierra 3500 HD SLE V8.6599cc Forced Induction::Turbo Kits 2007-2010 GMC Sierra 3500 HD SLT V8.6599cc Forced Induction::Turbo Kits 2007-2010 GMC Sierra 3500 HD WT V8.6599cc Forced Induction::Turbo Kits
