KEEP YOUR INTAKE AIR COOL

The IE FDS front-mount intercooler kit (FMIC) increases horsepower and eliminates heat soak. Get the most out of your tuned or big-turbo Audi 2017+ B9 A4, S4, or Allroad by installing the IE FDS intercooler system. The intercooler kit is complete and drop-in.

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 inlet 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 IAT (intake air temperatures) more so than competing intercoolers, thus offering the largest power gains possible.

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. (See dyno chart in power charts tab)

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 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. (See dyno chart in power charts tab)

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 with absolutely minimal modification. It has CNC machined mount points 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 kit comes complete with one FDS intercooler and all hardware needed for installation.

INSTALLATION

Install for the IE B9 FDS Intercooler will require a standard toolset, a couple of torx bits, and some technical expertise. We recommend reviewing our install guide and install an overview video before attempting the install. Installation Guide can be found HERE.

HORSEPOWER & TORQUE RESULTS

The IE Audi B9 FDS Intercooler increases horsepower & torque by decreasing IAT (intake air temperature) and reducing knock. This makes your car much more predictable and consistent because it will not heat soak rapidly like the OE Intercooler.

 

 

PRESSURE DROP RESULTS

Typically upgrading to a larger intercooler core results in added pressure drop, resulting in power loss. IE's FDS design eliminates this problem and works to deliver more boost to the engine by minimizing pressure drop across the intercooler. On the B9 platform, our FDS Intercooler reduces Pressure drop from 1PSI to .3- a drop of approximately 70% at Stage 1 power levels!

INTAKE AIR TEMPERATURE RESULTS

Our unique IE FDS Intercooler design for the Audi B9 platform consistently results in an IAT drop of approximately 20C-30C average at end of open throttle pulls compared to the factory intercooler.

IE FLOW DISTRIBUTION SYSTEM (FDS) FLOW RESULTS

The highly engineered FDS design unique to IE intercoolers uses a carefully shaped fin system located inside the intercooler end tank to force the path of intake air. This ensures charge air utilizes the full intercooler core more effectively than conventional intercoolers resulting is less pressure drop, lower IAT temps, and more power resulting in the most efficient intercooler design on the market.

Exact item ordered, quick delivery
Size: 9.5, Color: Black Polished Full Grain
I ordered these black Cole Haan penny loafers for casual wear with jeans, khakies, and even business casual with slacks and a jacket. They've always worked perfectly for these uses. The Cole Haan version is the most versatile and still meets my sophisticated look criteria. I wear a 9 1/2 M with almost all other shoes. I have found Cole Haan to run slightly wider and slightly shorter. This fit will work with thin and no socks and a little loose in width. . I'd likely order a 10 N next time. I tend to forget this but it runs consistent with me for Cole Haan. 5 stars for the shoe and service. My bad on the slightly off fit.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr
