Got a failed turbo on your 1.8T? Looking to increase the power in your A4 or Passat 1.8T? If the answer is yes to either of those questions the BorgWarner K04-015 turbocharger is perfect for you. Great bolt on performance upgrade, can be used with or without specific programming (only on stock ECU without stage 1, etc).
The KKK K04 is a straight bolt on turbo that can be used for multiple different reasons. Flows more volume than the standard K03. Can sustain higher boost pressures than the K03. Great replacement turbo if your K03 has gone bad. Can be used without any special programming although specific K04 programming is recommended to extract all potential power from the K04
