CFM Plus Ford 7.3L


For all you 7.3L owners, we heard your cry for a performance intake manifold and here it is. Our two-piece intake manifold system is not only the first aftermarket manifold system for the 7.3L diesel but its manufactured with the same quality and technology as all of our CFM+ Intakes. Using our Two-Piece System design,the cool air from the intercooler is now insulated and kept cool by the high temperature composite intake material. The extremely hot air from the turbo now exits through a separate aluminum elbow. By separating the extremely hot turbo-charged air elbow from the cooled air inside the intake manifold, we have negated the effect of transferring heat back into your cool air. Just like our other intakes maifolds, bench flow testing shows a significant increase in air flow through our two-piece system.This means better economy, more power, lower EGTs and faster turbo spool up.


The 7.3L Powerstroke Intake Manifold System uses our 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.

This means that as your cooled air returns to your engine from your intercooler it passes through the heated aluminum stock part which transfers heat right back into your air flow just before it goes to your engine.

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

Diesel engines thrive on cooler air and only our intakes can deliver it! Cooler air means more dense air which results in lower EGTS 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.
