• CSF Intercooler Upgrade for 4M RSQ8/Urus/Cayenne, Black Aluminum by Unitronic

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 this platform.

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 4M EA825 platform to begin applying corrections which subsequently lowers performance.
