This HF-Series intake is the result of years of experience and constant further development. The Air Box, as well as the Air Collector are completely made of carbon fiber. This allows us to guarantee the highest tensile strength and stiffness. 4x as durable as aluminum, low-vibration and gas- and pressure-tight. Perfect for optimum fresh air supply.
The new feature: The air filter is installed transversely to the direction of flow. This ensures that the maximum air mass can be taken in. The development was completely made in our company. With elaborate 3D scans and flow simulations, we were able to create the optimum performance combined with an unrivaled intake sound.
This HFI Carbon Air Intake Kit is suitable for RS3 with 367HP and 400HP, as well as for TTRS 8S models. Suitable for both, serial vehicles and vehicles with uprated engines (ECU remapping). This Intake Kit replaces the complete original air filter box incl. the air collector and the intake pipe.
