ADVANCED R&D
The Audi C8 RS6 and RS7 include a unique factory intake design built on the factory radiator shroud. This location provides access to cool air from the front of the grill. Still, it lacks the internal volume, flow optimization, and filter efficiency to support higher power from ECU tunes and turbo upgrades. Extreme engineering practices were required to redesign a proper motorsport intake maximizing the potential of all available space within the challenging factory intake location. The resulting IE performance system delivers power and sound with breathtaking looks for your 4.0TT twin-turbo engine.
STYLE & FUNCTION
The entire airbox is genuine carbon fiber providing superior heat dissipation, lightweight, and solid yet thin-wall construction. Carbon fiber can be molded into near endless shapes allowing our engineers to design complex angles, corners, and extremely tight tolerances to maximize flow and volume in the design without material restrictions or compromises. The final design is all performance on the inside while carrying a stunning gloss carbon weave finish on the outside.
MULTI-PIECE SYSTEM
Maximizing intake efficiency requires taking advantage of every millimeter of available space within the tight confines of the factory engine bay. By dramatically increasing the size and design of the air box's lower and upper sections, the intake can support much higher airflow and volume with superior laminar over the filter, providing unrestricted airflow for higher boost demands and power.
MAXIMIZED VOLUME
More power requires additional airflow. Maximizing the interior volume of the intake is an attack on two fronts. First, the upper lid has been increased in size, filling all available space under the hood with a much smoother transition to the inlets. Volume is further optimized by increasing the internal size and angle of the filter base. The result is far superior air supply on tap for tuned engines requesting more significant boost pressures than stock.
HIGH-VELOCITY DESIGN
Increased intake volume is only helpful if the air supply can reach the turbos effectively. High-level computational flow dynamic (CFD) software is leveraged to calculate the best possible internal angles and shapes to reduce turbulence and increase flow inertia. The organic and smooth transitions are a considerable departure from stock, aiding in faster spool times for reduced lag while reaching peak boost pressures at the earliest point in the RPM band possible.
PRESSURE ZONES
The airbox has been optimized with the performance advantage of multiple air supply avenues. The front air inlet receives outside high-pressure flow from the front of the grille and acts as a ram air design for most of the air supply. Additionally, the bottom airbox inlets pull extra air as required from the low-pressure zone under the intake. These dual zones provide a free air supply across the entire filter and ensure your intake will never be a power limiter for even the most extreme builds.
PERFORMANCE FILTER
The included high-performance air filter maintains superior filtration properties keeping your engine and turbochargers safe from outside contaminants while dramatically increasing performance. The cotton 4-pleat design allows the intake design to increase airflow velocity while retaining a low pressure drop as the airflow passes through the filter element.
UNIQUE SOUND
Installing your intake not only delivers a performance boost, but also releases a new symphony of turbo, throttle, and engine sounds that will make your throttle pedal more addictive than ever.
You drive a twin-turbo V8 flagship Audi; prepare to sound like one!
QUALITY FIT & FINISH
IE's 3D scanning tools create a digital duplicate of the vehicle's engine bay, grille, bumper, and hood. These scans provide an incredibly high-resolution environment allowing our engineers to take advantage of all available space and perfect an extremely high-end install.
HYBRID TURBO READY
iE 4.0T Turbo Inlet Pipes are designed to accommodate stock or hybrid turbos. Our CNC-machined and O-ring sealed adapter rings provide a smooth transition from the large inlet to stock or TTE1020 hybrid turbochargers. The turbo inlet is oversized and seamlessly tapers down to the turbo to meet air supply demands.
Stock turbo adapter rings are included with the optional iE Turbo Inlets. TTE1020 hybrid adapters coming soon.
DYNO RESULTS
Real-world power numbers are achieved using our in-house dyno cells to record the effect the optimized flow rate, air supply, and volume have on horsepower and torque. The testing was performed in controlled conditions with stock turbo inlets on the same day back to back. Dyno results show consistent and significant power gains of 69HP & 55ft-lbs on our Stage 2 tuned RS7 at high altitude!
Power testing was performed in SLC, Utah, at 4,226 feet of elevation. Vehicles at or closer to sea level can expect even higher power gains exceeding 70-80HP depending on ECU tune, matching hardware, and fuel type.
FLOW TESTING
All intake prototype designs undergo back-to-back flow rate testing to validate the engineering efforts and confirm real-world results from the computational flow software. The result of the final optimized intake system delivers up to a 230 CFM increase over stock!
| -IN. H20 | STOCK | IE INTAKE | IE INTAKE & INLET |
| -5 | 260 CFM | 416 CFM | 490 CFM |
| -10 | 388 CFM | 596 CFM | 695 CFM |
| -15 | 487 CFM | 730 CFM | 852 CFM |
| -20 | 570 CFM | 844 CFM | 982 CFM |
| -25 | 641 CFM | 945 CFM | 1097 CFM |
| -30 | 710 CFM | 1033 CFM | 1201 CFM |
The above gains are a result of various design details:
- The entire upper and lower airbox redesign provides organic transitions to optimize and speed up airflow while maintaining the lowest possible turbulence with excellent laminar properties.
- The internal volume increase feeds a significantly increased air supply to the turbochargers removing the factory restrictions and raising the ceiling for larger boost requests.
- The front ram air scoop and lower inlets provide multiple ambient temperature air sources for the engine to support greater demands from tuned and hybrid engines.
