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:

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