The 2.9L V6 twin-turbo engine in these models is equipped with an advanced indirect intercooling circuit. Unlike conventional systems, the charge air is cooled not by ambient air, but by a dedicated cooling water circuit. A reduction in the cooling water temperature therefore directly improves the cooling performance of the charge air. This is where the advantages of the Wagner Tuning Upgrade Water Cooler come into their own.
The newly developed Competition racing core of the Wagner Tuning high-performance radiator expands the radiator volume of the stock radiator by an impressive 55%. The optimized ratio between inner and outer cooling surfaces ensures maximum heat transfer while also ensuring sufficient airflow to adjacent components such as the engine radiator. Furthermore, the radiators are equipped with a heat-conducting, anti-corrosion coating that ensures long-term cooling. Installation of the system is straightforward and virtually plug & play thanks to our user-friendly installation instructions.
