Discover the new era of performance with the Wagner Tuning Performance intercooler, developed for Audi S8 models with the powerful 4.0L V8 biturbo engine. Experience an incomparable combination of power, performance and dynamics.
Our innovative intercooler has been specially developed for the demanding requirements of the Audi S8 models. It offers significantly improved cooling performance with up to 40°C cooler intake air temperatures, resulting in maximum mechanical and thermal relief for the turbocharger. With a high-quality cooling intercooler core that offers an additional 118% more external core volume compared to the charge air cooler fitted as standard, our charge air cooler sets new standards in terms of cooling performance. The ratio between the inner and outer cooling surface ensures maximum heat transfer and optimum internal air flow. CFD simulations were used to develop the end boxes from high-quality aluminum chill casting to ensure optimum air flow conditions. The result is outstanding cooling properties with minimal back pressure, which also makes this kit ideal for racing. Our intercooler is equipped with a thermally conductive anti-corrosion coating that ensures long-lasting durability. Installation of the complete kit is straightforward and plug & play thanks to our simple installation instructions.

Benefit from the numerous advantages of this product:
-Significantly improved cooling performance with up to 40°C cooler intake air temperatures
-Maximum mechanical and thermal relief for the turbocharger
-More power and torque for your engine
-100% pressure resistance
-Plug-and-play without modifications
-4x 1/8 NPT connections for measuring additional parameters
Suitable for all power levels
Treat yourself to the ultimate performance upgrade for your Audi S8 and experience a driving experience that will thrill you. Opt for the Wagner Tuning Performance intercooler and take your vehicle to a new level of performance and dynamics.


The 4.0L V8 biturbo engine of the Audi RS6 and RS7 models is equipped with an indirect charge air cooling circuit. The charge air cooling process is therefore not realized with ambient air as usual, but with a separate cooling water circuit. Lowering the cooling water temperature leads directly to an improved cooling performance of the charge air. This is where the advantages of our Wagner Tuning auxiliary water cooler come into play.
Our newly developed competition racing core increases the radiator volume of the standard water cooler by an impressive 92%. The ratio between the inner and outer cooling surface ensures maximum heat transfer and at the same time allows sufficient airflow for adjacent components such as the engine water cooler. The water coolers are also equipped with a thermally conductive anti-corrosion coating, which ensures a long-term cooling effect. Installation of the system is uncomplicated and plug & play thanks to our installation instructions.
Prepare your Audi RS6 / RS7 C7 for maximum performance and optimize its cooling system with our competition water cooler kit.
