IE's carbon fiber intake system flows 37% more than the stock intake & inlet on the factory turbocharger and up to 61% more on hybrid turbo setups. This increase translates to a maximized flow rate that significantly improves turbo & engine efficiency resulting in power gains of up to 19HP & 21ft-lbs on tuned engines! IE's engineers took a "no expense spared" approach to design the ultimate intake system solution that delivers on looks, fit, and, most importantly -power!

LEADING FEATURES

Take your driving experience to the next level with features that maximize flow rates, increase power, and improve sound for your turbocharged 3.0T engine.

  • High-gloss genuine carbon fiber construction
  • Reliable and seamless 1-piece design
  • Optional cast turbo inlet for a complete (and massive) air system
  • Up to 19HP & 21ft-lbs over stock (with IE turbo inlet)
  • Flow 37% more than the stock intake system
  • Flow 61% more than stock on hybrid turbo setups
  • Enhanced turbo & engine sound
  • Maximized turbo & engine efficiency
  • Factory style mounts
  • Stainless hardware
  • Multi-ply silicone with stop-flat edges
  • High-quality clamps
  • Powder-coated aluminum bottom plate
  • Stainless laser-etched logo plate
  • 5" pleated cotton filter

OPTIONAL TURBO INLET PIPE

Upgrade your intake with our optional cast turbo inlet for the most performance available from an intake system. This removes the significant airflow restriction from the small plastic stock inlet and maintains the largest size possible from the intake to the turbocharger. This combination increases flow from 11.52% (intake only) up to 61.49% over the stock intake and turbo inlet!

Turbo inlet pipe is an optional upgrade and can be purchased with your intake or added at a later date.

CARBON FIBER - MORE THAN STYLE

A large internal volume is required to maximize airflow. Using carbon fiber allows our engineers to create complex shapes and angles that are impossible to achieve with sheet metal bends. This manufacturing style utilizes every millimeter available in the engine bay, providing ample air supply and smooth delivery.

SEAMLESS DESIGN

The full carbon 1-piece airbox looks stunning while also eliminating all chances of air leaks, finicky install, rubbing noises, or parts working loose over time as found on typical multi-peace airbox designs.

BUILT-IN VELOCITY STACK

By incorporating a professional motorsport-style velocity stack into the airbox design, airflow is channeled from the sizeable internal airbox volume into the turbocharger as quickly as possible. The bellmouth shape creates a very high inertia flow from the massive filter with very low drag or power-robbing turbulence.

MULTIPLE PRESSURE ZONES

Engineered to support any power level, the intake takes advantage of multiple air supply avenues. The front large 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 plate louvers pull extra required air as needed 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.

UNIQUE SOUND

You drive a flagship S model Audi with a 6 cylinder turbocharged engine -sound like one!

The factory intake kills any engine sound to meet requirements for everything but fun. By upgrading to an IE intake system, you are taking full advantage of a performance design, including the turbocharger spool, engine throttle, and diverter valve sounds that come along with it. The unique velocity stack and bottom louver design create a tuned engine note that sounds classy yet powerful at the same time. This sound level is not heard through other brand closed box intakes and is a much more refined sound than found with open element style intakes.

HYBRID TURBO READY

Have plans for a bigger turbo? Your IE intake and turbo inlet will make the process of upgrading to a hybrid turbo a simple bolt-in job. Our cast turbo inlet design utilizes CNC-machined and o ring sealed adapter rings to fit either the stock or a variety of aftermarket turbos without hassle. The turbo inlet always adapts down to the turbo to not introduce any restrictions and maintain the largest size possible when upgrading turbos.

Hybrid turbo adapter rings are sold separately from the turbo inlet upgrade.

PRECISION FIT

3D scanning tools are used to create a digital duplicate of the vehicle's engine bay, grille, bumper, and hood. This provides an incredibly high-resolution environment to reverse engineer and prototype the intake design. This not only allow engineers to take advantage of all available room but also results in a perfect and extremely high-end install.

POWER RESULTS

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

FLOW BENCH TESTING

The proof is in the testing. Back-to-back flow bench results show constant and consistent gains of up to 61.43% CFM over stock! 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.

100 Percent Satisfied

I’ve researched the air gate for almost six months along with comparable versions from AWE, 034, APR and some of the lower end products. I finally decided to purchase the IE air gate and I couldn’t be happier. The insulation took less than 30 minutes and it look and sound amazing. I’d recommend to anyone interested in setting their car apart.

Looks Devine; Sounds Aggressive; Improves Performance

Bought with the turbo inlet and installed at the same time for maximum feel on the butt dyno. Car feels more responsive, and moves quicker. In the cabin, you don't really hear the sound. But at low speeds you can definitely hear the turbo breathing and it's music to my ears

Love it on my B9 S5 Sportback!

Installation was pretty easy and straightforward. Car sounds really good too. You can definitely hear the turbo come alive, and it's a nice noticeable sound from outside as well. Paired it with the inlet pipe, and it's even better!

Perfect fit with a strong turbo note

The installation was simple And straightforward. It's one-piece design is clean and adds a good look to the engine compartment. I was surprised with how much it improved the turbo sound. It is a bit pricey but well built and high quality. A must have for your B9.

I give it a 5 star but.....

I give it a 5 star because I believe it's a great product, gives good sound, and the fit and finish is really great. The install of the intake was beyond easy but if you also ordered the turbo inlet, that is where it got tricky. The install of the turbo inlet was super easy until it wasn't.........I believe you should be clear that the lower bolt is a total pain to get out then back in once the inlet adapter is put back on. I had to cut down an allen wrench just to get it to fit. When it could have been a 25-40min install it ended up taking a couple hours to get it all situated. Just a heads up and a suggestion or even including the actual Allen would have been awesome.
