APR Audi A4 B7 2.0T FSI S3 K04 Conversion Package

APR's S3 K04 Turbo Conversion is now available for the B7 model generation Audi A4 2.0T FSI. APR has developed an excellent entry level turbocharger upgrade for the 2.0T FSI engine by incorporating the OEM turbocharger assembly from the Audi S3 and coupling it with APR’s FSI Fueling Technology and expertly recalibrated engine management upgrade. APR's Engineering Team has developed a powerful and reliable turbocharger upgrade that maintains OEM engine bay appearance and offers up to 118 hp and 131 lb ft of torque over the OEM power output of the 2.0T FSI.

APR's engineers have expertly recalibrated the engine management system to allow for nearly flat torque delivery from 3000 RPM to 5500 RPM which results in a smooth linear pull throughout the power band. Keeping the track enthusiast in mind, this conversion package will not result in overpowering of the driveline but will allow for smooth acceleration to easily maintain control while cornering.

The Borg Warner K04 turbocharger selected by VAG engineers is perfectly sized for the 2.0 liters of displacement to allow for stout horsepower numbers as the RPMs increase with no dramatic fall off as redline approaches. This ensures plenty of power in the high RPMs for continued acceleration in the straights and positioning at the healthiest portion of the power band after corner exit.

Featuring APR's Patented EMCS program switching functionality and DirectPort Programming, APR's Engine Management Calibration for this conversion package allows for a range of Octane and situation specific calibrations to be installed simultaneously on your vehicle's ECU. These programs and features are able to be cycled through via your existing factory cruise control and activated in less than 20 seconds. You will be able to choose 1 to 4 Programs listed below.
