The Integrated Engineering MK5/MK6 FDS intercooler system was built from the ground up to offer the ultimate in performance for your vehicle. 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.  

This intercooler is very popular with GTI and Golf R owners who understand true performance.   Unlike typical front mount intercoolers, our FDS intercooler is installed in the stock location providing a stealth look while providing superior cooling.

-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 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, 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.

-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?
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.



This MK5/MK6 intercooler system features our IE FDS (Flow Distribution System) design on the inlet side cast end tank. IE FDS has been proven to distribute charge air uniformly across the entire area of the core. This is in contrast to other intercoolers on the market which rely on natural airflow across the intercooler, the IE FDS technology takes full advantage of the massive 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.


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 looks at each specific application and designs an intercooler that is properly sized for it, then begins prototyping and testing. Our engineers use Computational Fluid Dynamics (CFD) software to optimize the end tanks and FDS system for minimum pressure drop and maximum flow. Unlike competitor intercoolers, we use this software on each intercooler to design the application-specific FDS system to evenly distribute airflow.

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.



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 system offers the largest gains available by upgrading the intercooler and makes a perfect match for cars with upgrades from  ECU tuning to big turbo setups. The power increase is instantly noticeable and is seen across the entire powerband, as intake air temperatures are reduced.




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.  



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 MK5/MK6. 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 and leak-free.




The IE MK5/MK6 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, as well as a thorough installation manual.
