aFe Power BladeRunner Ductile Iron Ported Exhaust Manifolds; 46-40124

Bolt on diesel power with aFe's BladeRunner exhaust manifolds for your 08-10 6.4L Powerstroke. These ported ductile iron manifolds will reduce pressure loss to your turbocharger for increased performance and improve throttle response. The manifolds are compatible with all factory equipment including AC lines, heat shields, and EGR cooler for a true bolt- on upgrade. These manifolds have both the inlet and the outlet ports CNC machined to match the factory ports. This allows for maximum flow, without compromising the integrity of gasket sealing for a leak-free seal. An Exhaust Gas Temperature (EGT) port is incorporated into each manifold for easy installation of gauges or testing equipment. These manifolds are compatible with the stock up-pipes, which allows the manifolds to be installed without having to remove the turbocharger down-pipe or the up-pipes.
