Add ON3 XL Intercooler boots/clamps*:


Over the past few years we have been selling this unit and becoming extremely popular within the Cummins community. We are always stocking this item ready to ship daily. This is designed for the 2003 – 2007 Dodge Ram Cummins turbo diesel trucks. From testing, the truck dropped intake air temps significatly during driving around the city. Also the truck comes into boost quicker and noticed also a small increase in fuel efficiency. A QUESTION ASKED FAR TOO MUCH, is this unit a factory replacement or more of a performance related product? This intercooler trumps the factory unit in all aspects, its not even close to a comparison. This is designed for performance although it can be used and often is used for factory replacement. Our intercooler upgrade is far superior to the factory unit and used by many people pulling, drag racing as well as typical street driving duties.

This core is 2.75″ thick with 3.5″ inlet and outlets on the intercooler. As you can see the intercooler is massive and has a core size measuring 26″ across and 28.5″ tall! Which in turn is going to be a huge improvement over stock, keep your IAT’S in check and help make more power with better fuel economy.

Don't forget the 3.5" > 3" boots/clamps to make install complete.
NOTE: Manufacturer WILL NOT ship/sell to California.
Item cannot be shipped cost-effectively outside the continental U.S.

When installing our intercooler kit:

We have the end tanks cast with 3.5″ inlet and outlet to support greater hp numbers and flow. Your factory silicone couplers and tubing into the factory unit are 3″. So when installing our intercooler, it will require new couplers to adapt. They are not included with the price of the intercooler and must be bought separately. ***Does include new t-bolt clamps as well to keep couplers secured even under high boost application
