Why is the CFM+ the ultimate intake manifold?
Even without a computer it’s easy to see why the CFM+ flows so much better than the angular stock aluminum manifold with its nearly 40% flow restriction at the front mounting bolts. (Fig. 1) Made from high strength heat insulative composite materials, the CFM+ intakes offer the highest and coolest air flow available for your Powerstroke engine. Maximum performance and increased fuel economy come from the smooth uninterrupted air flow and composite materials that transfer heat into your engine air 900 times less than all cast aluminum stock or aftermarket intakes. But why does the CFM+ flow so much more air than the other oversized cast aluminum manifolds in the market and maintain lower air temps? 1) The very large center section of the competitor cast aluminum manifold may look impressive but it is very bad for flow. The inlet to the manifold from the inter cooler and the outlet of the intake manifold into the engine are very similar in cross-sectional area so when the center section
