This Carbon Fiber Intake System and Turbo Inlet for the B9 and B9.5 Audi S4 and S5 is designed to dramatically improve airflow over the factory equipment while supporting both the stock turbocharger and hybrid turbochargers via Unitronic's clever 53mm and 65.7mm 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 adds a striking presence in the 3.0TFSI engine bay as well.

Optimized Airflow

To validate its form through function; Unitronic engineers strategically used CFD to maximize the efficiency of this Intake System. After countless hours of test fitments and product validations through several iterations, the result is a design that maximizes the room available in the engine bay while exhibiting smooth volumetric transitions where every facet is effectively executed for form and function.

Proven Airflow Gains

Unitronic Hardware Engineers carefully benchmarked the OEM Audi S4 / S5 turbo inlet versus the Unitronic Turbo Inlet in a controlled environment using our in-house Superflow SF-1020 flow bench. Our team observed massive air flow gains of up to 57% with the Unitronic Intake and Turbo Inlet. This drastic air flow improvement allows the turbochargers to work more efficiently and achieve target boost with less stress resulting in improved reliability.
