The CSF Intercoolers for Audi C8 RS6/RS7 have been meticulously designed and engineered to fit exactly like the OEM units they replace. Utilizing all factory mounting points, the installation is straightforward with a “drop-in fit” design. No cutting or modifications are required, and there is no need for aftermarket shrouds or hoses. All mating OEM components can be reused and reinstalled. The 4.0L twin-turbo V8 in the RS6 & RS7 starts to experience debilitating heat soak and progressively increasing IATs with the OEM intercoolers. This results in the ECU pulling engine timing and drastically decreasing power output. The CSF by PWR Intercoolers solve this issue and allow vehicles to perform at optimal levels consistently and for prolonged periods of time. CSF recorded gains of 20 WHP and 18 WTQ with a stock tune and 10 WHP and 20 WTQ with a high-performance tune during dyno tests of the CSF #8194 (Audi RS6/RS7 High-Performance Intercooler System). Also, Intake Air Temperatures (IAT) were much more stable after multiple hard pulls resulting in more consistent dyno numbers.

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.

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 core The 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 Proven on CSF’s similar air-to-air twin intercooler systems, for both Porsche 992 Turbo/S and GT2RS, these cores eliminate heat soak and lower Intake Air Temperatures (IATs) to allow maximum performance of the vehicle for an extended period of demanding driving conditions.

One of the biggest advantages of CSF’s new C8 RS6/RS7 Intercooler System is the recovery speed in dissipating heat from the turbocharger system.

With the OEM intercoolers, the new C8 platform starts to exhibit heat soak and run-away increases in IATs, which then triggers the ECU system to pull timing out of the engine and subsequently lowers performance. As with other products produced through CSF’s PWR partnership, the 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 bolt-on modifications, higher performance tunes, as well as upgraded turbochargers.
