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 with the Unitronic Turbo Inlet. This drastic air flow improvement allows the turbocharger to work more efficiently and achieve target boost with less stress resulting in improved reliability.

Designed and Tested In-House

At Unitronic, hardware evolution begins with rapid prototyping utilizing their in-house Stratasys 3D printer. Within hours, Unitronic Engineers are able to have a complete working printed prototype, allowing for test fitments to be performed on the vehicle, functional testing to be completed and flow data collected to further validate the designs.
