The 7.3L PowerStroke Intake Manifold System uses CFM+'s composite material benefits by completely separating the turbo outlet elbow from the cool air engine inlet portion of the intake. The exiting turbo air temperature can range from 250deg-350deg F. This extremely hot air flows into stock cast aluminum single piece system and heats the entire part.

But with the CFM Plus 7.3L Intake Manifold System you can eliminate that heat transfer by separating the two flow path structures. CFM's turbo exit elbow is manufactured from cast aluminum to handle the extremely hot turbo exiting air and high turbo pressures, but the cool air returning from your intercooler is now insulated from under the hood heat and kept from any turbo heat transfer.

Diesel engines thrive on cooler air and only CFM intakes can deliver it! Cooler air means more dense air which results in lower EGT's, more power and performance, and better fuel economy. A cast aluminum intake acts as a conductor and transfers heat into the air flow at a rate of 900 times greater than our composite material.

All CFM Plus intakes are designed using proven engineering principles and the results are confirmed with bench flow testing. This model intake manifold system provides you with about 15% more air flow than the stock system.

As you compare the images of the stock system versus the CFM Plus system you will notice that the on the stock part both the elbow that attaches to the turbo and the inlet portion that attaches to engine have sharp corners for the bend areas. These sharp bends that you see on the outside translates to sharp bends and edges in the air flow path on this inside. This causes reduced flow and turbulence. This is typical of stock intakes as they are not designed for maximum air flow or performance.

The CFM Plus 7.3L Intake Manifold System is the world’s first aftermarket intake manifold system for the 7.3L PowerStroke.  Quality, Performance, and Economy is built into every part.
