Extensive real world testing has resulted in the undisputed champion of intercooler design for the 2.0T Audi A4.

Intercooler design consists of more than just finding the largest core that will fit on the front of the car.

Exposed frontal area, number of pressure charge rows, cooling fin count, and end tank geometry are some of the key parameters that need studying when embarking on an intercooler project.

As with most of our intercooler development, the use of sophisticated Computational Fluid Dynamics (CFD) software allowed us to study airflow and maximize our approach to lowering intake air temps even before we hit our chassis dynamometer. Our end tank went through no less than 14 design evolutions. By carefully choosing our cast aluminum end tank shape, along with the integration of a directional baffle, we were able to drop intake air temperatures a maximum 27 degrees F over stock, while also reducing restriction by half! Not only does that result in an additional 14 crank hp on a chipped car, it also means completely stable power under the hottest outside conditions, even when there is over 400hp under the hood with a big turbo kit.

Temperature drop, pressure drop, and overall core efficiency were logged and calculated through thorough dyno, street, and track testing, in all sorts of ambient conditions. View the Behind the Scenes tab for results.

This intercooler is simply massive in its abilities. Nothing else comes close.
