The addition of an intercooler by Dodge 5.9L Cummins pickup mid way through 1991 was the breakthrough in making more horsepower while decreasing heat. Today, every heavy duty turbo diesel pickup on the market is equipped with one. That being said, even those leave something to be desired. Alligator Performance's partners aFe Power, ATS Diesel, BD Diesel, Banks Power, High Tech Turbo and Mishimoto have larger intercoolers to keep your EGT's cool and your truck running even cooler.
