• APR offers IS20 and IS38 turbocharger upgrades for the 1.8T Audi A3, VW Golf, Alltrack, and Sportwagen

      APR is offering a factory reliable performance upgrade for 1.8T turbo four-cylinder equipped Audi and Volkswagen models. It is essentially factory reliable because APR is using factory turbochargers to boost output combined with APR's software.

      The IS20 turbocharger is utilized on the Golf GTI and the IS38 sees use on the Golf R as well as the Audi S3.

      If Audi/VW were to upgrade the 1.8T motors this is how they would do it themselves.

      So what kind of gains will you see? Take a look at this dyno overlay to get an idea:

      That yellow line? That is where the 1.8T starts. Not exactly a powerhouse. That red line pushing 325 horsepower to all four wheels? That is what you want. More than double the 1.8T factory output!

      No reason the 1.8T can't have the punch of its 2.0 big brothers:

      Both upgrades completely transform the 1.8T, adding between 104-188 HP over stock, depending on setup. With this release, we now support all 1.8T models in North America, as listed below:

      • Audi A3 1.8 TFSI - S Tronic
      • VW Golf 1.8 TSI - 5 Speed Manual & Tiptronic
      • VW Golf Alltrack 1.8 TSI – DSG – All Wheel Drive
      • VW Golf Sportwagen 1.8 TSI – 5 Speed Manual, 6 Speed Manual, Tiptronic & DSG – Front Wheel Drive & All Wheel Drive
