BD 6.0L Powerstroke Exhaust Manifold Set Ford 2003-2007

Heavy walled manifolds hold in exhaust gas temperatures to enhance turbine pumping efficiency. The runners have been ported to improve velocity and evacuate the cylinders. Manifolds are coated to resist corrosion and are pre-drilled for pyrometer probes. These units replace the old rusted and leaking stock exhaust manifolds that normally require extensive cleaning and machine work to be recovered from warping and distortion. The manifold set comes with both passenger & driver's side units and feed pipe mounting hardware. With the stock manifolds considered a maintenance item due to corrosion and leaking, this set is an excellent preventative replacement item whenever doing other engine work.Heavy walled manifolds hold in exhaust gas temperatures to enhance turbine pumping efficiency; Optimized runners to improve velocity and evacuate the cylinders; Coated to resist corrosion; Pre-drilled for pyrometer probes; Replaces old rusted and leaking stock exhaust manifolds that normally require extensive cleaning and machine work to be recovered from warping and distortion; 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.
