POLYMER AIRBOX

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.

SEAMLESS DESIGN

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.

BUILT-IN VELOCITY STACK

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.

TURBO INLET UPGRADE

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.

HYBRID TURBO READY

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.

HIGH-FLOW PRESSURE ZONES

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.

TURN UP THE FUN

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.

PRECISION DESIGN

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.

POWER RESULTS

Every inch of this intake system design has evolved from countless revisions, rapid prototyping, flow bench testing, dyno runs, and real-world verification to maximize performance benefits. The result is power gains of up to 19WHP and 21ft-lbs of torque, with even higher gains possible on hybrid turbo setups!  

FLOW BENCH TESTING

Our polymer intake provides consistent gains of up to 61.43% CFM over stock during back-to-back flow bench testing! This increase in CFM proves the upgraded intake system's efficiency over the factory parts and capability to provide any required airflow demands from ECU tunes and hybrid turbocharger upgrades.

The above gains are a result of various design details:

  1. The 5" air filter surface area and increased air volume improve turbo efficiency.

  2. The internal velocity stack provides a low-turbulence transition from the filter to the inlet.

  3. High & low-pressure zones channel low-temp airflow quickly to the engine while protecting it from radiant engine heat.

Easy Install, Great Results

I previously tuned my S5 with IE's stage 1 ecu & tcu tunes and was amazed by the results. I decided to see if I could expand on that with the intake system as well as the cast turbo inlet. If I was installing just the intake it would have been a breeze. The turbo inlet was challenging. But once it was all said and done, I'm very pleased with the results. Sounds is improved. Not obnoxiously but you can tell this pretty car is a beast by the sound. Seems like throttle response is improved too, which makes sense with the improved airflow and all. Looks cool too (even without it being in cf if you're on a budget like me). I would recommend for sure!

Perfect fit, works great!

Replaced a CTS Turbo 6” intake with the IE one, I have been amazed at how much of a difference it has made! The engine runs better between shifts and stop and go traffic, it appears the previous intake was taking in too much hot air from the engine bay. Highly recommend! My only wish is if there was a way to access the air filter front the top, whenever it comes time to clean you will have to remove the whole assembly to access the filter.

S4 Cold Air Intake

Easy install and perfect fit. The hardest part was removing the stock turbo elbow and installing the turbo elbow adapter. The upgraded look matches perfectly with the engine bay and the new sound is impressive as well. Thanks IE for all the support answering all my questions before my purchase. Now I just need to decide between the upgraded intercooler or the ECU tune.
