Turbo Systems B9 A4, A5, A4 Allroad 2.0T Hybrid Turbo
The iE B9 A4 / A5 Hybrid Turbo by Turbosystems erases the factory airflow ceiling to deliver a serious performance jump for your longitudinal 2.0T. This direct bolt-in hardware turns a quick car into a relentless powerhouse without sacrificing daily usability.
Spool Without the Wait
Budget hybrids often feel sluggish off the line. This ball bearing CHRA hybrid keeps power delivery crisp and immediate. Full boost arrives in the low 3000 RPM range, keeping the car's punchy, fun-to-drive character alive on the street.
Relentless Top-End
For beast-mode performance, your engine needs to pull a ton of air. This Stage 3 turbo upgrade delivers maximum airflow and boost pressure with larger, more efficient wheels, pushing your B9 A4 to new heights of aggression in motion.
More Flow, Less Compromise
The enlarged turbine housing is specifically balanced to lower exhaust back pressure without the typical "big turbo" tradeoffs. This is critical for maximizing pump gas performance. You get high-RPM flow while keeping the snappy, fast-spooling feel of a much smaller unit.
Stage 3 Foundation
This hybrid turbo is the foundation for the iE Stage 3 ecosystem. As part of a complete, calibrated, high-performance package, it’s a key player in unlocking your B9 A4’s full potential with our iE B9 A4 Turbo Systems Hybrid Tune.
