The Integrated Engineering MK5/MK6 FDS intercooler system was built from the ground up to offer the ultimate in performance for your GTI, Golf R, or 2.0T Audi/VW. When increasing the power output of your engine it is extremely important to ensure it has the proper cooling to match. It packs a very large intercooler core into the space available, a full 54% larger than the OEM core. This large core delivers cool air to the engine under all circumstances, increasing power and torque and simultaneously reducing heat soak.  

Product Summary


Keep your GTI and Golf R cool with the IE FDS  Intercooler. The IE FDS intercooler 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.




When you begin modifying your VW/Audi 2.0T it will quickly become necessary to upgrade the intercooler. Once upgrades such as ECU tuning, exhaust systems, and turbo upgrades are introduced, intake air temperatures begin to rise, resulting in massive 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.



Go faster longer, retain power pull after pull. 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.



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 uses Computational Fluid Dynamics (CFD) software, 3D printed prototypes, and our in-house dyno facilities to optimize the end tanks and FDS system for rapid cooling, minimum pressure drop, and maximum flow before production. 



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.



The IE FDS intercooler 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. 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 U.S 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.  


The IE MK5/MK6 intercooler comes complete with high quality, 5 ply reinforced silicone hoses, which allow connection directly to the factory outlet and throttle pipes of your GTI or Golf R. We also include every piece of hardware needed for installation.



Install for the IE MK5/MK6 2.0T FDS Intercooler is a direct factory replacement and does not require any permanent modifications to the vehicle, however, the installation will require some technical expertise. You can view and download the install guide  HERE.

At what point will I need the IE FDS intercooler for my car?

The IE FDS intercooler is a great upgrade for cars with an upgraded turbo, as well as cars using the factory turbo with an aggressive ECU tune. The OEM intercooler is known to experience heatsoak with added horsepower, especially if the car is driven hard for long periods of time. The IE FDS intercooler eliminates the heatsoak issues and provides a cool charge air, even under extreme driving conditions.


What 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, a billet adapter to connect the silicone hose to your OEM turbo outlet pipe, silicone hose clamps, and necessary bolts and washers.


Is there any modification 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. View install guide here.


Do I need to purchase anything else to install the IE FDS intercooler?

This intercooler includes all necessary hardware and parts for installation. Since installation requires removal of the radiator, you will need to drain the cooling system. We also offer coolant, which is available separately. Aside from that, there is nothing else needed for installation.


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.


Will this intercooler work with an aftermarket radiator?

We have not confirmed fitment with any aftermarket radiators, as the IE FDS intercooler was designed around the proven factory unit. We recommend using the OEM radiator only.

Absolutely Amazing
This was a little bit of a pain to install on my MK6 Golf R, but it was WELL WORTH IT. No temperature seems to hot, this product keeps everything cool! The sheer size of this thing is also no joke! I noticed some extra noises (good ones obviously) and my vehicle seemed to be running much better, and faster!

Seriously effective
I've had this IC for a couple of years now but I thought I'd throw in my support for this essential piece of hardware, as it deserves the kudos. Right now my town is experiencing the craziest heat wave in years; but my Audi TTS seems completely undeterred when armed with IE's intercooler, whereas it used to bog down with the factory IC under the most minimal of temperature increases.
Some surprising but not insurmountable fitment issues aside, i've been super happy with this piece and its performance. Excellent.

It is a great upgrade over the stock intercooler all the hardware came with, it was easy to install no problem there, But the only thing that could be better if they double check the hose to make sure that they are right for the car and that they look like the ones in the picture that u see on the website.
