We are proud to announce our new intercooler designed specifically for C7/C7.5 Audi A8, S6, S7, S8, RS6, and RS7 models equipped with the powerful 4.0T engine. This intercooler is a game-changer, providing an array of performance-enhancing features that set it apart from the stock OEM core.

  1. Enhanced Core Durability: Experience a dramatic increase in core strength compared to the OEM core. Our intercooler is engineered to withstand the rigors of high-performance applications, reducing the risk of failure when boosting your Audi’s power.
  2. Improved Water Flow: Our intercooler uses standard size hose connections, but still the flow has improved due to superior core efficiency. This increased water flow rate ensures your Audi remains cool and optimally performs under pressure.
  3. Rapid IAT Recovery: During spirited drives and high-performance pulls, IAT (Intake Air Temperature) recovery is vital. Our intercooler facilitates faster IAT recovery, ensuring your Audi consistently delivers its best performance.
  4. Superior Airflow: With a higher CFM (Cubic Feet per Minute) rating than the OEM core, this intercooler overcomes the limitations of the stock system. Enjoy improved airflow and the potential for higher power output.
  5. Enhanced Cooling Efficiency: The CTS Turbo Intercooler features additional fin density and added cooling columns, contributing to improved efficiency. This translates to lower intake temperatures and more reliable performance.
