The IE air intake system for your Audi S6 or S7 4.0TT engine is the result of extensive engineering methods to validate a truly unique performance design. 3D scanning, radpid protoying, rigerous back-to-back flow bench validation, dyno testing, and track proven to produce real power, torque, and sound to elevate your driving experience.

Flow rate testing is performed to validate the design against the restrictive stock airbox. Using our in-house Superflow bench, the maximum possible flow rate in CFM (cubic feet per minute) is measured in gains over stock at a variety of test pressures (in/H20). A higher flow reading means the intake system can support increased demands from ECU tunes and turbocharger upgrades.

In addition to flow bench testing, real world power numbers are achieved using our in-house dyno cells to see the effect the improved flow rate has on horsepower and torque. The testing was performed in controlled conditions on an IE Stage 1 tuned car performed the same day back to back on multiple octanes.

POWER SUMMARY

The gains are a result of various design details:

The large internal volume, massive air filter, and multiple air sources allow for an unrestricted supply of airflow.
The internal velocity stack provides a low-turbulence transition from the filter to the inlet pipes.
The carbon fiber airbox both channels ambient temperature air quickly to the turbochargers and protects the airflow from engine bay heat.

QUALITY COMPONENTS

To match and exceed the high-end fit and finish of the flagship S model S6 & S7, our intake system has been engineered without sacrifices, compromises, or shortcuts. Only the best materials and design features have been chosen to set the benchmark of 4.0TT intakes.

High-gloss true carbon fiber construction
Integrated carbon velocity stack
5.5" engine specific pleated cotton filter
Full carbon twin inlet pipe
Factory-style mounting
Stainless hardware
Powder-coated aluminum bottom plate
Multi-ply silicone with stop-flat edges
Stainless laser-etched logo plate

COMPLETE ASSEMBLY

The airbox assembly comprises our carbon filter housing, 5.5" high-flow filter, aluminum bottom plate, carbon velocity stack/inlet pipe, stainless hardware, and mounting provisions for a complete bolt-in solution.

CARBON EXCELLENCE

Carbon fiber can be manipulated into almost limitless shapes allowing our engineers to utilize every millimeter of space within the tight factory engine bay. The unique architecture and contours allow for a larger internal volume and smoothed airflow while simultaneously shielding it from radiant engine bay heat.

HIGH-FLOW VELOCITY STACK

In order to gain the highest flow possible, the velocity stack transitions airflow from the large surface area of the air filter and smooths its travel to the inlet pipes. This clean reduction accelerates the airflow into very high inertia which eliminates power-robbing drag and turbulence.
