BD Diesel 1041482 Exhaust Manifold Set PowerStroke 6.4L - Ford 2008-2010 F-250/F-350/F-450/F-550

The 6.4L manifold set is crafted with a heavy duty 0.25" thick-walled Hi-Silicon ductile casting, this makes these manifolds thicker to combat cracking due to high exhaust temperatures. To maximize exhaust flow, computational fluid dynamics were used to optimize flow and exhaust port geometry. BD's exhaust manifold set is the perfect replacement for reliability, performance and peace of mind.Ports are gasket matched to maximize exhaust flow; Performance high-silicon ductile cast iron; Pre-drilled for pyrometer probes and pressure gauges; High temperature black paint; Includes 6 exhaust studs (mates to up-pipe flange); Cylinder head to exhaust manifold gaskets included; Fully emissions compliant; Our goal is to be an innovative company and a world class manufacturer that distributes products Worldwide for North American Diesel vehicles.; Our goal is to be an innovative company and a world class manufacturer that distributes products Worldwide for North American Diesel vehicles.
