Engineered Performance for Audi, VW, Porsche & Skoda

APR's S3 K04 Turbo Conversion is now available for the Audi B8 A4/A5 & Q5 2.0 TFSI Valvelift engine. APR has developed an excellent entry level turbocharger upgrade for the 2.0 TFSI VL engine by incorporating the OEM turbocharger assembly from the Audi S3 and coupling it with APR's 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 75kw and 148nm of torque over the OEM power output of the 2.0 TFSI

Reliability, drivability, stealth and enhanced performance that cannot be bested are the highlights of APR's newest OEM-component based conversion package.

APR's engineers have expertly recalibrated the engine management system to allow for nearly flat torque delivery from 2800 RPM to 5000 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.

Optional OEM Exhaust Compatibility

While a full exhaust is recommended for maximum power, If you're in a situation where running a high flow exhaust is not permissable, APR has also developed software specificly to use with your OEM Exhaust system. You may switch between high flow exhaust software or OEM exhaust software free of charge any time you alter your exhaust system.

APR's Patented EMCS Technology

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. You will also be able to add APR Security Lockout, APR Fault Code Erase and APR Anti-Theft features.
