Integrated Engineering Turbo Systems B9 A4 Hybrid Turbo
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, itβs a key player in unlocking your B9 A4βs full potential with our iE B9 A4 Turbo Systems Hybrid Tune.
