The most important feature of the CSF High-Performance Intercooler Upgrade is the PWR intercooler cores. CSF’s strategic relationship with PWR has allowed the inclusion of this core, which is unlike any other available for the C8 RS6/RS7.

3mm tall, rolled tubes with turbulated inner fins maximize the dissipation of heat from the charge air flowing through the pressure side of the intercooler coreThe 4.85mm tall multi-louvered fin is the most efficient fin in the high-performance industry, with performance similar to PWR’s Formula-1 grade race intercooler cores

When analyzing intercooler performance, it’s important to not only consider maximum cooling abilities, efficiency, and resistance to heat soak, but also recovery time. The CSF High-Performance Intercoolers performed optimally in nearly all demanding conditions.

With the OEM intercoolers, they start to exhibit heat soak and run-away increases in IATs nearly immediately, especially when combined with increased boost levels and demands of a tuned vehicle, which then triggers the Bosch MG1 ECM found in the C8 platform to begin applying corrections which subsequently lowers performance.
