A special rotomold process is used to manufacture our premium polymer 3.0T intake airbox. This method leverages complex shapes and angles to maximize internal volume for air supply and smooth flow for a true performance design. This Molding style also produces consistent wall thickness, strong corners, and superior heat resistance for a cost-friendly intake without compromises.
The entire intake is designed as a single-piece airbox to offer a seamless and complete look with an above factory quality fit and finish.
Our motorsport-designed velocity stack creates a smooth transition from the large filter area to the turbo inlet with excellent laminar properties. This uniquely engineered detail produces a high inertia flow with reduced drag and power-robbing turbulence.
Adding the optional cast turbo Inlet upgrade further reduces significant air restrictions while maintaining the largest size possible from the airbox to the turbocharger. The intake and turbo Inlet further increases airflow from 37% (intake only) up to a combined 61% over stock!
Turbo Inlet pipe is an optional upgrade and can be purchased with your intake or added at a later date.
The intake and turbo Inlet designs offer a straightforward and bolt-in job of available hybrid turbo upgrades. Our turbo-specific CNC-machined and o ring sealed adapters always maintain the largest size possible without introducing flow restrictions. Upgrading to a TTE or Pure Turbo hybrid is easy, simple, and hassle-free.
Hybrid turbo adapter rings are sold separately from the turbo inlet upgrade.

IE's multi-zone intake design delivers all the performance benefits of an open-filter intake while maintaining protection from hot engine bay air from under the hood. A constant ram air supply is forced in from the Grille inlet, while any additional air demands are supplied from the low-pressure zone through the filter plate louvers. This dual-zone approach ensures airflow demands for any power level, even the most extreme builds.
The byproduct of a true performance-designed intake is more than power. Our uniquely engineered velocity stack, pressure zones, and extensive internal volume also work together to release a Myriad of turbo spools, engine throttle, and diverter blow-off sounds that Transform your S4 or S5 with the under-hood acoustics of a genuine sports car .
3D scanning tools are leveraged to create a high-resolution digital environment. This technology allows IE engineers to use all available space for a complete performance design while ensuring a hassle-free fit and installation.
