Want to eliminate heat soak when you start adding horsepower to your B9 A4, S4, A5 or S5? The factory intercooler just does not cut it when you start adding power adders to your Audi. Whether you are daily driving or taking your B9 to the track, you are going to need to swap out the under performing OEM intercooler and replace it with a performance intercooler.

Integrated Engineering's FDS aftermarket front mount intercooler for the B9 platform will just do that. A direct drop in replacement, no cutting no welding which leaving installation to be done in just an afternoon leaving you right back to pushing your B9 to the next level.

FDS (Flow Distribution System)

The IE FDS (Flow Distribution System) has shown to distribute charge air uniformly across the inlet end of the core. Compared to other intercoolers out in the industry that rely on natural airflow across the core, the Integrated Engineering FDS technology uses precisely shaped and placed fins cast into the inlet plenum to fully take advantage of the big core volume effectively using the whole core. As a result, the IE B9 FDS front mount intercooler has been shown to reduce IAT (intake air temperatures) more than its' competitors.

Technical Features

Increasing horsepower of your B9 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 competitor intercoolers. 

Precision Engineered

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

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 airflow 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, decreasing the need for the turbocharger to work harder to produce the required boost levels. This allows the turbocharger to deliver more usable boost pressure to the engine. 

FAQ

At what point will I need the IE FDS intercooler for my car?
With extensive testing, we have found that all B9 chassis vehicles have very poor factory intercoolers and can benefit greatly from our intercooler upgrade. Most beneficial on vehicles equipped with stage 1 software or higher, it is necessary to upgrade with a big turbo setup.

What all is included with the IE FDS intercooler?
The intercooler kit includes the direct-fit core, install brackets, 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.

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