  • Optional Dodge Replacement Pipe:  The factory plastic intercooler intake pipe is prone to cracking or shattering when exposed to heat or high boost pressures.  Upgrade to BD's heavy duty intercooler intake pipe available in powder coat polished finish.


Compressed air is heated air. When you combine an aggressive fuel curve with elevated boost levels, high inlet temperatures can result. That's why BD Diesel developed the Cool-It Intercoolers. With 57% more cooling surface area and a 33% thicker core (2.68" vs. 2"), the BD Diesel Intercooler increases cooling effectiveness to approximately 90%, compared to only about 70% with the stock intercooler. That can mean an air temperature reduction of up to 200 degrees over the stock intercooler. The BD Diesel Cool-It Intercooler also features 36% larger inlet and discharge tubes (3.125" vs. 2.625") and can easily handle up to 100 psi. of boost and over 1500 cfm, while holding pressure drop less than 1 psi. A direct, bolt on replacement for the stock unit, the BD intercooler is the best looking, best performing intercooler on the market. Hoses and spring loaded T-bar clamps are included.
