CTS Turbo B9 A4/A5 Silicone Turbo Inlet Hose

The CTS Turbo silicone turbo inlet hose replaces the restrictive factory plastic unit on 2016-2021 Audi B9 A4 and A5 models. Constructed from high-grade reinforced silicone with embedded polyester reinforcement layers, this inlet hose resists heat soak and maintains its shape under vacuum pressure. The smooth bore design eliminates the internal corrugations found in the standard hose, promoting more efficient airflow to the turbocharger inlet. Direct OEM fitment ensures straightforward installation using factory mounting points and clamps without modification.
