The most important feature of the CSF by PWR RS6/RS7 Intercooler System is the Formula-1 grade intercooler core. CSF's strategic relationship with PWR has allowed the inclusion of this core, which is unlike any other available in the performance aftermarket. Featuring two rows of rolled cooling tubes with inner fins, these cores make for the most efficient intercoolers available. Because of this, they are able to eliminate heat soak and lower IATs much more efficiently than traditional Bar & Plate or Tube & Fin designs. This gives us maximum performance for extended periods of time under demanding driving conditions and for vehicles with increased power levels through modifications and tuning. As with our other products produced through our PWR partnership, our new RS6/RS7 Intercoolers feature 100% TIG-welded machined billet aluminum end tanks vs. the OEM crimped cast aluminum end tanks. This feature is not only aesthetically pleasing, but is also stronger for longevity and durability on high-performance vehicles. The CNC machined billet end tanks are ready to withstand increased boost pressures from higher performance tunes, as well as upgraded turbochargers.
