Unitronic Carbon Fiber Inlet for B9 S4 / S5 3.0TFSI

This Carbon Fiber Turbo Inlet for the B9 and B9.5 Audi S4 and S5 is designed to dramatically improve airflow with massive gains over stock while supporting both the stock turbocharger and hybrid turbochargers via Unitronic’s clever 53mm and 65.7mm adapter rings.

Constructed of high quality carbon fiber, this new B9 S4 Turbo Inlet and B9 S5 Turbo Inlet features a large 85mm bore and smooth transitions to draw massive amounts of non-turbulent air from the airbox. A factory style PCV connection is maintained for OEM-level fitment as well.
