For more information, visit www.P65warnings.ca.gov.The APR K04-64 Turbo System (T2100009) is the ultimate drop-in turbocharger upgrade for Longitudinal 2.0T engines found in the Audi B7, B8, and B8.5 A4/A5. This system is engineered to provide a substantial increase in power and torque, delivering performance similar to the factory Golf R or Audi S3. With lightning-fast transient response and minimal lag, power comes on quickly and remains strong throughout the entire RPM range.
At the heart of this system is a customized Genuine Borg Warner K04-64 turbocharger, featuring a CNC-machined billet compressor wheel and a durable stainless steel exhaust manifold. Unlike off-the-shelf units, APR has integrated the Diverter Valve (DV) directly into the compressor cover, mirroring the factory setup to eliminate clutter and potential boost leak points. This "budget-friendly" big turbo solution offers world-class reliability and includes the necessary APR Stage 3 K04 ECU Upgrade to maximize the hardware's potential.
Features:
- Massive Power Gains: Provides significant horsepower and torque increases, transforming the 2.0T into a high-output performance machine.
- Genuine Borg Warner Components: Uses a K04-64 core with a high-tech billet compressor wheel and stainless steel manifold for maximum reliability.
- Integrated DV Design: The Diverter Valve is integrated into the compressor cover for a clean, simplified installation that removes common boost leak paths.
- Software Included: This kit includes the APR Stage 3 K04 ECU Upgrade (must be installed by an authorized APR dealer).
- Complete Installation Kit: All required gaskets, nuts, bolts, washers, studs, and one-time-use clamps are included for a headache-free install.
