There are two common types of air-to-air intercoolers; a Bar-Plate and a Tube-Fin design.

Bar-Plate: This type of core is made by layering structures of flat plates separated by rectangular spacers. While this design provides better heat transfer(cooling), the inherit disadvantage is more restrictive flow across the core compared to the Tube-Fin design.

Tube-Fin: This type of core is made by extending a series of tubes from one end plate to another. This design offers more efficient internal flow, hence less pressure drop across the core due to greater flow path area compared to a Bar-Plate intercooler of the same external size. The draw back of this design is less efficient heat transfer.

The factory Porsche intercoolers(for the 996 and 997 TTs) are Tube-Fin design. They are inexpensive to manufacture(as they are similar to an engine radiator)and provides only sufficient cooling and flow for the intended factory horsepower rating.



Our newest Blitzkrieg 127mm ICs use a very unique Hybrid design. The exterior offers the superior heat transfer characteristic of the Bar-Plate design, while the interior has the superior airflow feature of the Tube-Fin design(minimal pressure drop across the core). By integrating the positive attributes of both designs we have developed the ultimate air-to-air intercoolers for the twin turbo Porsche.



Another important benefit of our intercoolers is that we designed them to work with the factory ducting(requires a small amount of trimming the plastic duct work due to thicker cores) and retain the factory positive-locking couplers. Standard hose clamps work fine for our “low-pressure” single turbo systems, but in a higher boost application such as the factory twin turbo Porsche, we believe in the superior reliability of the factory positive-locking couplers.



We do supply some other companies with this core technology but this is a completely proprietary system and we feel it is the most advanced intercooler available on the market today.
