The Audi air to water-cooled turbo and supercharged applications required an advanced configuration that further expands on their cooling system and addressed higher cooling capacity and water volume than any other product.
We took this challenge seriously and with our help from Audi owners/friends, we now provide you a cooling solution that performs amazingly on your Stock, upgraded or higher boost tuned applications.
Our unique patented design uses the entire area of these large vehicles to provide you with excellent cooling capacity, a ONE-Gallon water volume, and amazing results.
At the point of design and taking to market, no other heat exchangers in the market were designed this way. This design allows for water to stay on the cooling stage longer and dissipate heat longer than other normal single and dual-pass systems.
- High-density fin core for excellent heat dissipation.
- Purge air easier with included bleed port.
- Bleed port included for assisting air removal during installation.
