Unitronic 3" Turbo Inlet Elbow for the 2.5TFSI EVO (EA855) engines, found in the 8V.2 RS3 and 8S TTRS, is made from aircraft grade cast Aluminum and is engineered as a direct bolt-on upgrade for the stock frame Borg Warner® turbochargers that produces gains of +18 HP / +8 LB-FT TQ and increases airflow by 12% through eliminating airflow restrictions and significantly improving overall turbo efficiency.

As is with all of its performance products, Unitronic utilizes only the latest industry leading tools, equipment, and computer aided design software that is packed with the latest technology from our technology partners at Creaform® and Stratasys®.  These tools and technology help to achieve a design that not only optimizes airflow and speed, but also eliminates airflow restrictions that are present with the factory piece, while fitting within the engine bay constraints, and offers direct compatibility with the factory intake and many aftermarket intakes that are presently on the market, without needing any adapters, additional couplers, or other accessories.

Unitronic began with 3D scanning the 2.5TFSI EVO engine bay and OEM components with it's in-house 3D scanner.  Once 3D scan data has been collected and processed, Unitronic's Hardware Engineers then interact with the 3D models to identify fitment constraints, mounting locations, other component locations, etc. to ensure the final product fits perfectly.

Overall product design proceeds through, not only focusing on increasing overall performance of the product, but also the small and often overlooked aspects of the product's design and function are of utmost importance to Unitronic.  In this case, Unitronic's Engineers worked on optimizing the air speed at the compressor inlet, just as Audi's Engineers did, as cited in their published literature.  As you can see in the comparison examples, air speed at the compressor wheel shows a relative uniform velocity profile across the opening.
