Wagner Tuning Competition additional water cooler water cooler for Audi S4/S5 B8 (3.0 TFSI) – 92% more cooling capacity Maximize the performance and reliability of your Audi S4/S5 B8! With the Wagner Tuning Competition auxiliary water cooler kit, you can optimize the charge air cooling water circuit of your 3.0L V6 supercharged engine (3.0 TFSI). Experience a noticeable reduction in cooling water temperature, which leads to a direct increase in performance – ideal for stock and tuned vehicles. Why this additional cooler is a must for your Audi S4/S5: Massive cooling volume expansion: The new Competition racing mesh increases the cooling volume of the standard water cooler by an impressive 92%. Direct performance increase: By reducing the coolant temperature, the cooling performance of the charge air is noticeably improved, resulting in optimized engine performance. Maximum heat transfer: The optimal ratio between internal and external cooling surface ensures maximum heat transfer while maintaining sufficient airflow for adjacent components. Durable and reliable: Equipped with a heat-conducting anti-corrosion coating for long-lasting and stable cooling performance. Easy installation: Installation is straightforward thanks to detailed installation instructions and plug-and-play design. Technical detail: Optimization of the 3.0 TFSI engine The 3.0L V6 supercharged engine (often referred to as 3.0 TFSI) uses its own cooling water circuit for intercooling. Although this indirect principle is efficient, it quickly reaches its limits under high loads in standard equipment. This is where the Wagner Tuning auxiliary water cooler kit comes in: the 92% increase in volume drastically reduces the temperature in the charge air cooling water circuit. This enables the engine to deliver consistently more power, especially in warm outside temperatures or when driving sportily.
