2003-04 5.9L Dodge Cummins Intercoolers / Hoses

An intercooler functions identically to a radiator, except instead of water, compressed (and therefore heated) air passes through the intercooler’s core. Meanwhile, ambient air passes through the external fins, removing excess heat energy. Cooler air is more dense, and therefore, the engine can benefit from more pounds of air for a given amount of time. 

Compressed air is heated air—and when you mix high boost pressure with an aggressive fuel curve, the result can be inlet temperatures as high as 500 degrees F.  

We at DPP offer a perfect solution, the BD Cool-It Intercooler.  With a larger surface area and thicker core than the stock unit, it is sure to keep things cool.  Couple this with larger tubes, and stronger tanks to handle high boost levels, and you've got a great addition to your Cummins!

And for those simply looking to upgrade their existing intercooler, or have already purchased a Cool-It Intercooler, we also offer high strength intercooloer hose kits capable of handling high boost levels, along with Clampco spring loaded clamps for keeping the air inside, where it counts!
