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.

Proof that lightning strikes twice ... Weir has done it again!
Format: Hardcover
According to a 2003 article on the NASA website, "NASA-funded scientists have recently learned that cloud-to-ground lightning frequently strikes the ground in two or more places ..." and that the third and fourth strokes of a lightning flash will follow the same path as the second stroke. In other words, lightning DOES strike the same place twice. But you don't need to search the web for this information. If you want proof that lightning strikes twice, just read Andy Weir's newest book, Project Hail Mary, and you'll see that Weir has created a giant sci-fi bestseller, in the same electric path as The Martian. Ryland Grace has a puzzle on his hands. He wakes up without a clue as to where he is, but he seems to be alone except for a computer AI that was keeping him alive. Unfortunately it didn't seem to be doing the same for two others in his ... wherever he is ... as he notes the decayed corpses in their creches on the ... well, it's a ship. A space ship. And bit by bit Grace puts the pieces of the puzzle together. An alien microbe has been discovered. Ryland Grace is brought on to the science team to learn more about the life form because Grace, currently a middle school science teacher, wrote papers about the notation that there does not need to be water to create life. Only in a biozone such as Earth's would water be needed, but other building blocks could be used in other systems. The science community as a whole mocked Grace, which is why he left and went on to teach kids, but now, he may be the best suited to understand this new life form. And as he remembers more and more, he also remembers that this life form is feeding on the energy output of the sun, which is decreasing the energy that gets to Earth, which spells disaster - as in the end of all life as currently known - on Earth if something isn't done. Scientists discover that Sol isn't the only star that is losing its energy output - likely due to the alien consumption, but that there is one star, in the center of all the known stars losing their energy, that remains constant with its output. In which case, the answer to the survival for Earth is likely found there, at Tau Ceti. The world's best scientific minds come together (by force and coercion) to create a ship that can get to Tau Ceti in twelve years (using the alien microbe as fuel) with shuttle pods to bring back answers to how to save the planet, but for the crew, it's a one-way trip. Knowing why he's there is only the first puzzle for Grace. Now he has to figure out how to save Earth. There's a very small window of time for him to discover the way to save the human race and get the answers sent back. Take too long and the shuttles will return to a dead planet. This book is amazing. Author Andy Weir brings us back to the magic that made The Martian so successful - an abandoned scientist trying to survive. But Ryland Grace's story is more complicated because he's not just trying to survive, but also help humanity survive. There's lots and lots of science - which is part of Weir's writing signature - and there's also a really wonderful story. It's hard for me to tell you just what I liked about this book because anything I write will be a spoiler and a huge part of the joy in this book is making the discoveries with Ryland Grace. Grace is our main character, but through the liberal use of flashbacks, we have a full cast of characters - at least one quite important to the story. Everyone is unique and individual which makes it easy to read, but just as with The Martian, where Mark Watney's personality carries the story, Ryland Grace here is the smart-mouth, sometimes funny, obsessed scientist infusing his personal tastes into his discoveries. He's also quite smart - which is good since he will need his intellect to save all of humanity. This is a page-turner. I did not want to put this book down. Neither did my 21 year old son who picked up my copy after I was well into it and finished it before I did. And days later he's still talking about how much he liked it and quoting sections of it to me at the dinner table. I hope Ballantine Books will do a very large print run because this is going to be huge seller and you definitely don't want to miss out on the biggest thing to come out in 2021. Looking for a good book? Project Hail Mary by Andy Weir is proof that lightning strikes twice as this has all the excitement and energy of Weir's debut novel, with a more complicated storyline that will hold the reader all the way to the end.

Excellent Hard Sci-Fi… Until the Politics Pull You Out
Format: Kindle
I was really excited to dive into Project Hail Mary. As a longtime Isaac Asimov fan, I’ve been craving fresh, modern hard science fiction that actually respects the science. This book delivered — at least for a while. The author injects real science into the story in a way that’s both fun and fantastic. You don’t need to be an engineer to follow it; a solid high-school education is plenty. The concepts stretch your imagination without ever feeling impossible, and for the first chunk of the book I was hooked. I genuinely thought I’d found a new favorite author. Then the jarring interruptions started. Out of nowhere you get yanked out of the immersive sci-fi world by modern political pandering that feels completely unnecessary. A random parenthetical about Columbus “discovering an already inhabited world” when comparing something to the New World. Casual pronoun lectures. Characters selected or described by race and identity in ways that scream “check the boxes.” These moments don’t serve the story — they feel injected. Once you notice the author’s leanings, it becomes hard to unsee. Each time it happens, the fantasy evaporates. It takes several chapters to sink back into the story… only for the next micro-lecture to pull you right back out. Overall, I loved the writing, the hard science, and the imagination. It’s some of the best sci-fi I’ve read in years. I just wish the author had trusted the story instead of sneaking in real-world politics. It’s like eating the best meal of your life… and then finding a hair or two in it. Strongly recommended for the sci-fi, with the above caveat.

A Good Intriguing Start
Format: Kindle
A very good read. I thought Hickman wrote the best version of Doom, but this story so far is exceeding my expectations. This is a well written Doom, intelligent, strategic, all the things you want a good villain to be. And that’s the thing, Doom hasn’t done anything one could call necessarily villainous yet, so at this point you’re kind of on his side. I’m curious to see if the writers can pull off a heel turn that doesn’t have him suddenly act out of character or do something incredibly stupid in order to show his villainy in the end.
