The Dodge Cummins inline-6 is well known for its smooth power delivery and engine longevity.Mishimoto has released an intercooler for the 2003-2009 5.9/6.7 Cummins that is built to last, just like your truck.The Mishimoto intercooler is manufactured with robust cast aluminum end tanks and a dense bar-and-plate core.This intercooler allows for decreased intake temperatures, improved airflow, and reduced pressure loss.Our engineers developed an intercooler with increased core volume that can support substantial boost pressures and lower EGTs in your stock or modified truck.Compared to factory units, the Mishimoto intercooler features larger outlets for increased airflow.This intercooler includes two silicone boots with DuraCore technology and our signature constant-tension T-bolt clamps for consistent and durable holding power.Mishimoto DuraCore technology is the synthetic material that comprises the innermost layer of all Mishimoto silicone diesel boots.Compared to normal silicone, DuraCore provides superior resistance to heat, pressure, fuel, and oil.This effectively increases the life of our boots by preventing leaks and blowouts.Offered in black or silver, the Mishimoto 5.9L/6.7L Cummins intercooler is protected by our signature lifetime warranty.
