APR Intercooler System - 2.5 TFSI EVO (TT RS)

  PRODUCT DESCRIPTION The APR Intercooler System is a massive front mounted upgrade that dramatically reduces intake air temperature (IAT), minimizes heat soak, and provides increased performance!  The system is an easy to install, direct bolt-on design, that is recommended at every stage of performance. APR’s engineers tested each intercooler in a multitude of tests to show the impact the APR intercooler has on intake air temperature.  The following tests were conducted with a 2018 TT RS using our APR Stage 1 ECU Upgrade, 93 octane fuel and no other modifications.  Ambient conditions during the stock intercooler tests were 72°F and 97.9 kPa with 80% relative humidity.  Conditions were similar later in the day during the APR Intercooler testing with 74°F and 98.18 KPa with 78% relative humidity.  This gave the APR Intercooler no added advantage over the stock system during the tests. The temperature difference between the stock and APR intercooler directly translates to more horsepower
