Experience the full performance of your Audi S8 with the Competition water cooler kit from Wagner Tuning. The 4.0L V8 biturbo engine of the Audi S8 models has an innovative indirect charge air cooling circuit. Instead of using ambient air, the charge air is cooled with a special cooling water circuit. By lowering the cooling water temperature, the performance of the engine is directly increased, and this is precisely where the Wagner Tuning additional water cooler kit comes in. Our newly developed competition racing mesh increases the radiator volume of the standard water cooler by an astonishing 66%. The unique ratio between the inner and outer cooling surface enables maximum heat transfer and ensures sufficient airflow for adjacent components for efficient heat dissipation. In addition, our water coolers are equipped with a thermally conductive anti-corrosion coating that ensures a long-term cooling effect. Installation of the system is simple and straightforward thanks to our detailed installation instructions. Benefit from an improved cooling circuit and experience optimized performance from your Audi S8. Ready to maximize your driving experience?
