After being hounded by second-generation owners for months, our team decided it was time to fulfill their needs and develop an awesome intercooler upgrade for the 12V and 24V. We would be designing our cooler with a few key features that would set it apart from the factory unit.

  • Cast aluminum end tanks for smooth airflow and unmatched durability
  • Extremely efficient bar-and-plate core
  • Direct fit for the 12V and 24V second-generation trucks

First Test Vehicle: 24V

After hunting around for a few local vehicles, this 24V ended up in our shop. A big thank you to the vehicle owner for lending us his truck for development.

Factory 24V Cooler Removal

We didn't waste any time with this project and set to work removing the factory cooler from this truck. Along the way, we would be capturing measurements from the truck to see just how much we could expand the size of our intercooler design.

These trucks are relatively easy to work on and disassemble. We had the factory cooler out in a fairly short time.

Second Test Vehicle: 12V

Next, we rolled in a 12V truck to pull the cooler on this vehicle as well. By having both vehicles in the shop, we can ensure that our design will be applicable for vehicles with either engine.

Factory 12V Cooler Removal

Intercooler removal for the 12V is similar, and we set to work pulling the bumper to remove the cooler.

Soon enough, we had the factory cooler out to begin evaluating our design.
