The CTS Turbo turbo inlet pipe for Audi RS3 8V and Audi TT RS 8S is made from cast aluminium and has a diameter of 4″.
The factory turbo inlet pipe is one of the system’s restrictions when increasing performance. This pipe is designed to provide the greatest possible flow while maintaining a precise fit. Its volume is increased by 78% compared with the standard turbo inlet pipe.
The larger diameter improves airflow to the turbocharger, giving the 2.5T engine more air to operate at maximum performance.

- Precisely machined fit for the factory turbocharger; versions for hybrid turbochargers are planned for release later
