CFM+ 94-98 Dodge 5.9L Cummins Carbon Appearance Intake Manifolds

The CFM+ intake for the Dodge Cummins 5.9L diesel offers up 44% more air flow than your current stock intake manifold. Its high strength, high temperature, engineered composite material has a heat transfer rate of 900 times less than cast aluminum. This means that not only are you going to get the highest flow of air, but also the coolest. Lower EGTs, higher performance, and better fuel economy, places this intake manifold ahead of the pack in today's growing diesel performance market.

CFM+ intakes are designed using proven engineering principles and theresults are confirmed with bench flow testing. As you can see in the picture the stock intake pinches off or restricts the air flow at the mounting bolt location. This is typical of stock intakes as they are not designed formaximum air flow.

The primary function of an aftermarket intake manifold is to flow more airto the engine.Our CFM+ intakes flow at a rate more than 40% higher thanstock and between 15% and 25% higher than competitive aftermarketintake manifolds. The chart shows the results from bench flow testing using our Cummins 5.9L intake versus stock and competitive aftermarketproducts.More air means better economy, more power, lower EGT’s better throttle response and less work for your turbo.

CFM+'s patented manufacturing technology allows us to produce a single piece hollow structure that is engineered to maximize air flow and eliminate any restrictions.

Competitive products, as shown attempt to reduce restrictions by creating an oversized center section. While this may look impressive, in the case of air flow, bigger is not always better. The increased sized of the flowpath actually slows the air flow resulting in pressure drop and significant pumping losses.
