The CTS Turbo 4″ intake pipe is designed for the 2.5T EVO engines in the Audi RS3 8V.2 and Audi TTRS 8S. It is used together with the CTS Turbo 4-inch cast turbo inlet.
It allows the factory airbox to be used while completing the entire 4-inch intake path. The system is compatible with the original airbox and provides more efficient airflow, more power and torque throughout the rev range, with a moderate increase in intake sound.
