CTS TURBO B9 AUDI A4, AllRoad, A5, S4, S5, RS4, RS5 HIGH-FLOW INTAKE (6" Velocity Stack)

The CTS Turbo high-flow intake system features a 6-inch velocity stack engineered specifically for B9 platform Audi vehicles including A4, A5, AllRoad, S4, S5, RS4 and RS5 models from 2018 onwards. This intake utilises a velocity stack design to smooth and accelerate incoming air, reducing turbulence at the entry point. The larger inlet diameter works with the factory turbo system to optimise airflow characteristics. CTS Turbo manufactures this intake to provide a direct replacement solution with improved breathing capacity over the standard factory airbox arrangement.
