Unitronic® has released its Carbon Fiber Intake System and Turbo Inlet for the B9 and B9.5 Audi® RS 4® and RS 5® equipped with the twin-turbo 2.9TFSI® engine. This RS 4 / RS 5 Intake and RS 4 / RS 5 Turbo Inlet are designed to dramatically improve airflow with gains of up to 38% over the factory equipment while supporting the stock turbochargers and TTE720 hybrid turbochargers via Unitronic's clever 48mm and 51mm adapter rings.

As with all Unitronic Intake Systems, this unit provides improved throttle response, seamless integration, and perfect fitment while greatly enhancing turbo induction sounds. Its stunning 2/2 twill carbon fiber weave also adds a striking presence in the 2.9TFSI engine bay.

At Unitronic, development begins with setting the objectives; performance, efficiency, aesthetics, and quality. Operations start with 3D scanning the 2.9TFSI engine bay and OEM components with its in-house 3D scanner. Once 3D scan data has been collected and processed, Unitronic Hardware Engineers interact with the 3D models to identify fitment constraints, mounting locations, other component locations, etc., to ensure the final product fits perfectly within the “envelope.”

The Unitronic Air Duct takes advantage of the large opening in the OEM grille. Thanks to its smooth transitions, it draws massive amounts of air straight to the Unitronic Airbox without turbulence. The Airbox (shared with other B9 2.0TFSI and 3.0TFSI applications) takes full advantage of the available room in the engine bay to maximize the air fed into the turbochargers. As with our popular 2.5TFSI EVO Carbon Fiber Intake System, this Airbox features diagonal slits which enhance turbocharger induction sounds and DV recirculation sounds with drainage provisions for water ingress.

In addition to finding airflow limitations with the factory airbox and air duct, the factory turbo inlet was also identified as an airflow restriction; therefore, Unitronic engineered its B9 RS5 Turbo Inlet to alleviate restrictions and complete the package. Constructed of the same high-quality carbon fiber, this Turbo Inlet features a larger bore to draw massive amounts of air from the Unitronic Airbox, then, with the help of its integrated divider, sends equal amounts of air to the individual turbochargers. Using our unique 48mm or 51mm adapters, this Turbo Inlet is designed to work with the factory turbochargers or the TTE720 hybrid turbochargers for the B9 2.9TFSI platform. A factory-style PCV connection is maintained for OEM-level fitment as well.
