Audi B8 A4/A5 & Q5 S3 K04 Turbocharger System

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 leve

l 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 116 hp and 113 lb ft 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 betw

een high flow exhaust software or OEM exhaust software free of charge any time you alter your exhaust system.
