K04 Turbocharger Upgrade Kit

The Unitronic K04 Turbocharger Upgrade Kit is engineered for the Audi A4 B8.5 2.0L TSI 2008+ and other vehicles equipped with the 2.0 TSI AVS platform. This comprehensive kit utilizes a genuine Borg Warner K04 turbocharger, specifically modified with retooled compressor and exhaust housings to ensure seamless integration with Audi's longitudinally mounted engine configuration. This careful adaptation negates the necessity for a specialized downpipe. Unitronic precisely recalibrates the ECU to unlock the full potential of the K04 Upgrade Kit and supporting hardware. When utilizing 93 octane fuel, the system is capable of delivering an impressive 335 horsepower and 300 torque. Independent testing on a MAHA LPS3000 Dynamometer by Unitronic confirmed these figures, achieving 335 HP / 297 TQ on their in-house B8 Audi A5, which was equipped with Unitronic's complete performance hardware and Stage 2+ Performance Software for the 2.0 TSI AVS platform. To accommodate users with stock clutches, Unitronic has developed specific software calibrations that incorporate torque management strategies to help preserve the longevity of the factory unit. This ensures that power is delivered effectively while maintaining the original appearance of your 2.0 TSI's AVS engine. The kit includes Unitronic Stage 2+ Performance Software, a modified Borg Warner K04-0064 Turbocharger, specialized silicone hoses, and all necessary hardware for installation, including gaskets, crush washers, and mounting components.
