High-Flow Intake (6" Velocity Stack) | Audi B9 A4, Allroad, A5, S4, S5, RS4, RS5 | CTS Turbo

Overview

CTS Turbo is proud to announce our new intake system for the B9 AUDI A4, AllRoad, A5, S4, S5, RS4, RS5 (2017-2021 models)

We designed our system to work in conjunction with the OEM air scoop to seamlessly force cold air into the air intake system. Air then flows through our high flow 6" velocity stack air filter for maximum engine performance.

Our single-piece proprietary molded silicone couplers allows for smooth entry of air into the engine providing peak power gains ranging from 10-12HP on a stock car.
All of the components included in the CTS air intake system work flawlessly together to provide increased horsepower and torque throughout the entire power band and an aggressive race-inspired sound. Turbo spool up and diverter valve release are a lot louder!
