KEEP YOUR INTAKE AIR COOL

The IE FDS front-mount intercooler kit increases horsepower and eliminates heat soak. Get the most out of your tuned or big-turbo Audi A4 by installing the IE FDS intercooler system. The unit is drop-in and requires no cutting, trimming, or modification.

FDS (FLOW DISTRIBUTION SYSTEM)

The IE FDS (Flow Distribution System) has proven to distribute charge air uniformly across the inlet end of the core. In contrast to other intercoolers on the market which rely on natural airflow across the core, our FDS technology uses precisely shaped and placed fins cast into the intake plenum to fully take advantage of the large core volume effectively using the entire core. As a result, the IE FDS intercooler has been proven to reduce intake air temperatures more so than other units available, thus offering the largest power gains possible.

TECHNICAL FEATURES

Increasing horsepower of your B8 A4 is a simple task with several tunes and upgraded turbos available. However, it is important to keep in mind that increasing horsepower will result in heat soak of the stock intercooler and parasitic power loss. The IE front-mount intercooler system was designed to directly replace the factory unit, while utilizing a much larger core and our proven FDS (Flow Distribution System) to effectively utilize that larger core. These features allow for much higher cooling efficiency than the factory system, thus reducing intake air temperatures and safely increasing horsepower output. The IE FDS intercooler is also a direct fit, requiring no cutting, modification, or time-wasting hassle during installation. Read below for more in-depth information on each intercooler feature.

ELIMINATE HEAT SOAK

Heat soak occurs when the heat generated exceeds the cooling capacity of the intercooler. The most common symptom is the noticeable loss of power after long term acceleration or several back to back power pulls. By greatly increasing the core size and useable area of the core with FDS technology, we have eliminated the heat soak, keeping the intake air temperatures consistently lower than OEM and competition intercoolers.

PRECISION ENGINEERED

Unlike other intercoolers that are simply put together to fit on the car and offer a larger core, the IE FDS intercooler line receives special treatment from start to finish. Our engineering department use Computational Fluid Dynamics (CFD) software to optimize the end tanks and FDS system for minimum pressure drop and maximum flow.

Once the end tanks have been designed and flow has been optimized, the 3D models head over to our 3D printing studio to manufacture the initial prototype. The 3D printed end tanks fastened onto a production core for testing. To validate the FDS technology, we test each model of intercooler in a controlled environment on our in-house engine dyno. A total of 16 temperature probes are placed on the core, with a column of 8 on either side. This allows us to collect data at multiple points on the inlet side and outlet side of the intercooler to verify temperature distribution across the core. Once that data has been collected, it is analyzed and used to determine if changes in location or pitch of FDS channels are necessary before going to production.

DECREASED PRESSURE DROP

Along with lower intake air temperatures, the large core within the IE intercooler also decreases pressure drop when compared to the factory unit. Simply put, pressure drop is the amount of pressure that is lost as air travels through the intercooler. As boost pressure is raised, pressure drop typically begins to climb. By using a larger core that flows much more freely than the factory core, pressure drop is reduced, reducing the need for the turbocharger to work harder to produce the required boost levels.

HIGH-QUALITY CONSTRUCTION, PERFECT FITMENT

Not only does it offer the highest cooling efficiency on the market, the IE FDS intercooler also offers perfect OEM replacement and requires no modifications to install. Many other kits available require cutting and drilling for fitment, which is the last thing you want to do to your B8. With CNC machined mount points, each and every IE intercooler allows you to reuse the factory mounting points and installs as if it were a factory piece.

You will also find that the IE intercooler receives the same attention to detail and quality as every other IE product, with cast and machined end tanks, precise TIG welding, and a dense bar-and-plate core. Every intercooler is tested on our in-house intercooler testing station before shipping, ensuring that it is ready to install.

COMPLETE KIT

The IE B8 intercooler comes complete with high quality, 4 ply reinforced silicone hoses, which allow connection directly to the factory outlet and throttle pipes. We also include every piece of hardware needed for installation. Click here to view & download the thorough installation manual.

DYNAMIC STEERING FITMENT

Vehicles equipped with Audi's dynamic steering systems include a large cooling loop mounted to the front of the radiator. This cooling loop does not allow installation of the IE intercooler and will have to be deleted or modified to allow fitment. At this time we do not officially support this application.

INSTALLATION

Install for the IE B8 FDS Intercooler will require a standard ttoolset, a couple torx bits, and some technical expertise. We recommend reviewing our install guide and install overview video before attempting the install. Installation Guide can be found HERE.

FAQ

At what point will I need the IE FDS intercooler for my car?
With extensive testing, we have found that cars with stage 2 software or higher will benefit from upgrading the intercooler. It is absolutely necessary to upgrade with a big turbo setup as well.


What all is included with the IE FDS intercooler?
The intercooler kit includes the direct-fit core and all install hardware including heavy duty black silicone hoses, silicone hose clamps, necessary bolts and washers, and an installation manual.

Are there any modifications required to install the intercooler?
No! The IE FDS intercooler is a direct replacement for the applications listed above. There is no trimming, cutting, or modification needed for installation.


Do I need to purchase anything else to install the IE FDS intercooler?
This intercooler includes all necessary hardware and parts for installation. Vehicles equipped with Audi's dynamic steering systems include a large cooling loop mounted to the front of the radiator. This cooling loop does not allow installation of the IE intercooler and will have to be removed and replaced with an auxiliary mounted kit. If you have a B8 equipped with dynamic steering, contact our sales team for a cooling loop solution.


What kind of power increase will I see with the IE FDS intercooler?
The power increase is dependent on the turbo setup and the boost levels that you are running. The larger the turbo setup and the higher the boost pressure, the larger the gains will be with the IE FDS intercooler.

How much horsepower will the intercooler support?
We have tested the IE FDS intercooler to over 600hp successfully with room to grow. Supported power is in the 650-700hp range, but will ultimately depend on the turbo setup and operating conditions.

Comfortable chair
Color: Cream, Size: PU Leather(No Wheels)
Ordered this chair for my daughter for Christmas. It's a great chair. It's very comfortable. She wishes it had wheels. I didn't see a way to add wheels to this base, either. Still a good chair. You have to make sure where you put it you can spin to get out of it. Pushing it back and forth on carpet doesn't work well.

Great Office Chair
I purchased this chair to replace the old one in my son's room. I really like the look and style of this chair. It was easy for me to assemble and the riser functions really good and the stability of the base is very good. I like the wide design as it has more back support and seat support.

Comfortable, Stylish, and Great for Casual Seating
The OLIXIS Criss Cross Legged Chair is a really nice option if you prefer sitting cross-legged or want a wider, more relaxed seating style compared to a traditional office chair. The armless design and wide seat make it easy to shift positions throughout the day without feeling restricted. Comfort-wise, the padding is decent and supportive for short to moderate sitting sessions. The adjustable height and swivel function work smoothly, and it’s easy to find a comfortable position whether you’re working at a desk, doing makeup, or just using it casually in a bedroom or home office setup. The minimalist look is also a plus—it blends well with modern decor and doesn’t take up as much visual space as bulky office chairs. Assembly was fairly straightforward and didn’t take long. One thing to note is that since it has no wheels, it’s not ideal if you need to move around your workspace frequently. Also, while it’s comfortable, it may not be the best choice for long, full workdays compared to a high-back ergonomic chair with more lumbar support. Overall, this is a stylish and functional chair that works great for light office use, studying, or casual seating—especially if you like the criss-cross sitting position.

Perfect “Hair-Doing” Command Chair
Color: Leather-beige, Size: Luxurious(With Wheels), Color: Leather-beige, Size: Luxurious(With Wheels)
As a physician, mom, and military officer, my mornings already feel like a tactical operation: breakfast, cartoons, and hair time before we roll out. My old high‑back desk chair turned every ponytail into a wrestling match with the chair back. This low‑back, armless chair has officially become my hair‑doing command center. What I love: • Low back + no arms = easy kid access. My daughter sits facing the desk, snuggled in her blanket, eating breakfast and watching TV. I can stand right behind her and actually reach her hair without a chair back or armrests blocking my elbows. No more asking her to twist sideways and slowly slide off the chair while I chase her head. • Wide, comfy seat for both of us. The seat is generous and supportive with thick cushions. I have plenty of room and my daughter is perfectly comfortable for our whole morning routine. She’s happy, I’m not bent at weird angles, and the whole process is smoother (and quieter!). • Looks and feels more expensive than it is. The faux leather upholstery is gorgeous in person and feels soft and substantial, not flimsy. It blends right in with our bedroom furniture and doesn’t scream “office chair.” • Thoughtful packaging & painless assembly. Everything arrived in perfect condition, very well protected in the box. The instructions were clear, all hardware was labeled, and it took me under 10 minutes to assemble by myself. • Glides & adjusts smoothly. The chair rolls, swivels, and raises/lowers easily and quietly. No squeaks, no sticking. I can move her closer to the desk or spin her toward me with one hand while holding a hairbrush in the other. A quick heads‑up: The chair is on the larger side (which I personally love), so if you’re looking for a tiny, petite chair, check the measurements. For me, the extra space is exactly what I wanted. Bottom line: If you also use your bedroom desk as a hair‑doing station, homework hub, or breakfast bar, this chair is a game‑changer. Comfortable, stylish, easy to assemble, and priced competitively with similar chairs—while actually making our chaotic mornings run a little smoother.

The perfect desk chair for sitting cross-legged—plus it rolls!
Color: Leather-beige, Size: Luxurious(With Wheels), Color: Leather-beige, Size: Luxurious(With Wheels)
This chair is absolutely amazing if you like to sit cross-legged while working. The seat is incredibly wide, giving you plenty of room to get comfortable without feeling cramped against the armrests. The smooth faux leather is awesome. I am honestly impressed with the price vs quality. The padding is nice for my 13 yr old daughter to sit cross legged on. The cushion is thick and supportive, and it has held its shape really well without flattening out. I also love that this specific model has wheels—a lot of these wide cross-legged chairs come with flat bases, so having the mobility to roll around my desk space is a huge plus. It looks high-end, feels sturdy, and was very straightforward to assemble. 10/10 recommend!
