2013

With our first prototype intercooler and shroud assembly complete, it was time to test fit and make necessary changes or adjustments.

Prototype Cummins Intercooler Test Fit

Using the factory mounting brackets, we bolted our components into place.

The front shroud fits nice and snug against the front bumper and grille. The core is definitely in an ideal position for optimal airflow.

Our team then worked to install the rear intercooler shroud, which mates with the cooling fan plastic shroud.

It was here that we ran into a slight fitment issue. The altered core size we designed pushes the shroud farther back toward the engine. Unfortunately, this means our shroud contacted the steering gearbox.

A bit of work with the cutoff wheel, and we had space to install the prototype.

Our product line for the Dodge Cummins continues to grow each year with the addition of interesting components that help you take your truck to the next level. These include efficient aluminum radiators, durable silicone hose kits, as well as top-notch intercoolers and intercooler piping kits. Our intercooler coverage ranges from 1994 through 2012, but in 2013, Dodge changed the Cummins intercooler design substantially. So once again, we are ready to take a shot at improving the factory system.

Factory Cummins Intercooler

Test vehicle for 6.7L Cummins intercooler development

Like previous generations, the 2013+ models feature an air-to-air intercooler. The primary change in 2013 was the mounting location of this cooler. Previous years saw the intercooler incorporated into the front stack with the radiator, AC condenser, and other coolers.

In 2013+ models, the cooler is mounted below these other heat exchangers and utilizes its own ducting for airflow.
