BD Diesel Cool-It Intercooler 03-09 Cummins
2003-2009 5.9/6.7L Cummins
More Surface Area, Better Flow, Reduced Inlet Temperature!
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. That’s why BD developed the new Cool-It intercooler.
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.
With 57% more cooling surface area and a 33% thicker core, the Cool-It increases cooling efficiency to approximately 90%, compared to only 70% for the stock intercooler. That can mean a temperature reduction of up to 200 degrees Fahrenheit!. At the same time, 36% larger inlet and discharge tubes (3.125-inch vs. 2.625-inch) and cast tanks with internal support struts can handle up to 100 psi of boost and over 1500 cfm, while holding pressure drop to less than 1 psi pounds per square inch.
The Cool-It intercooler’s extruded tube design offers numerous advantages compared to other designs on the market:
- Highest thermal efficiency
- Highest consistency of internal structure
- Greatest strength, resistance to “ballooning” and separation
- Unobstructed air passage to engine radiator
For towing heavy loads, the Cool It intercooler is highly beneficial, as it will keep intake air temperature in check during long hauls at high ambient temperature. The BD Cool-It intercooler is a direct, bolt-in replacement for the stock intercooler, and is the best looking, best performing intercooler on the market. Hoses and heavy-duty spring-loaded T-bar clamps included in some kits.
