Eventuri Porsche 911 Turbo/ Turbo S 991 Carbon Fibre Intake System allows the vehicle's turbos to work more efficiently. By replacing the single factory airbox with two separate patented Venturi housings, the turbos are able to spool and generate boost with less drag.
As a result, the wastegate duty cycles are reduced resulting in peak boost at lower RPM and therefore performance is increased. The two individual filters provide a larger filtration area as compared to the single stock panel filter. Furthermore, in order to keep inlet air temperatures down, the Venturi housings are sealed against an air duct which draws ambient air from the same location as the stock system. Since the 911 Turbo engine bay is densely packed, high IATs can only be avoided by ensuring a fully sealed intake system. The combination of a smoother airflow path to each turbo with low IATs results in higher performance and a sharper throttle response over the stock airbox.
