03-07 Powerstroke 6.0 BD Diesel Exhaust Manifolds Cooling Filters alone can clog orHeavy 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
