LEADING FEATURES
THE ONE AND ONLY FDS™
Cooling your 2.5T engine for the most power possible comes down to efficiency. What is the point of a large intercooler core if you can't effectively take full advantage of the entire space? IE's Flow Distribution System (FDS) places precisely engineered fins inside the end tank to force airflow evenly across the whole surface area to distribute the heat more effectively and recover faster. When drastically reducing air intake temperatures for the most significant power gains possible, IE FDS intercoolers are the proven cheat code.
NO BOOST LEAKS
The RS3 & TTRS 2.5TFSI engine is no stranger to big boost. Designed for any power goal, the inlet and outlet ports are specifically designed and in-house CNC machined to prevent boost hoses from popping off. Our engineers have paid close attention to detail with a flat-stop edge and beveled grooves for a high-friction surface that grips your hoses and locks them in place for good.
RELIABLE STRENGTH
The end tanks are manufactured from high-quality aluminum castings with ultra-thick and reinforced mounting for long life and worry-free operation. All mounting bosses and surfaces are in-house precision CNC machined and hand-verified for an exact fit.
IN-HOUSE TIG WELDED
For maximum quality, finish detail, and outstanding quality, every intercooler is meticulously in-house TIG welded by our intercooler welding specialists. Every unit undergoes a strict post-welding multi-point critical inspection and is tested on our leak-down station before shipping. This level of manufacturing ensures a reliable product ready to install and perform right out of the box.
PERFECT FIT
Your intercooler kit is the maximized size for ultimate performance while retaining a perfect stock-like replacement that requires no installation modifications. Includes all necessary hardware to install and fit vehicles with or without adaptive cruise control (ACC) without purchasing additional brackets.
European and ROW (rest-of-world) models may require a US crash bar for installation.
DEFEAT HEAT SOAK
IE's FDS Intercooler is your ultimate weapon against heat soak. Heat soak occurs when the heat generated by the turbocharger and engine exceeds the cooling capacity of the intercooler. The most common symptom is the noticeable loss of power during WOT acceleration or several back-to-back pulls. By increasing the core size and useable area of the core with FDS technology, we have significantly reduced intake air temperatures consistently lower than OEM and competition intercoolers.
INTAKE AIR TEMP (IAT)
This graph measures intake air temperature (IAT) heat gain from back-to-back testing of consecutive runs. Three wide-open throttle pulls were made while recording the IAT gains at the intercooler. The result was up to 28.6% lower IAT over the stock intercooler on a Stage 1 car!

POWER GRAPH
Real-world power numbers are achieved using our in-house dyno cells to see how the intercooler upgrade affects horsepower and torque. The testing was performed in controlled conditions on a stage 1 car. This testing shows that large power gains are achieved with the intercooler by reducing IATs.

FDS DYNAMICS
This comparison uses advanced Computational Fluid Dynamics (CFD) software to detail our FDS fin design's result on flow through the intercooler end tank. Notice the increased charge air distribution entering the top and across the intercooler core. The better this flow is distributed will increase intercooler efficiency and the speed at which it can expel heat from the core.
The above gains are a result of various design details:
- The massive increase in core size dramatically reduces heat soak.
- The internal FDS design forces air to utilize the entire core volume increasing efficiency.
- Lower intake air temps and reduced pressure drop increase horsepower and torque.

Another quality Quick Start book
Format: Paperback
Haven't gotten that far into the book yet, but so far the material is good.
IMO, the book would be far better if it had a spiral binding like the Python Quick Start books I bought. Programming type books are much easier and better to use when they lay flat.
This would probably make the book more expensive to purchase, but would be well worth it.
The contents of the book are well laid out starting with simple basic topics and progressing through the more advanced ones. The chapters on Asynchronous JavaScript and JQuery were, IMHO, light in the amount of information provided. The book is designed/written to provide a "quick start" on JS, but I think that there could have been more details provided for these two topics.
All in all this book provides an adequate introduction to doing JS coding.
Any plans on doing an advanced Javascript book to cover topics like map and other advanced programming constructs?

Great Javascript resource for learning the basics!
Format: Kindle
This book was a great resource for helping me to learn Javascript. It walked me through step by step and provided me with tools to build some solid skills. I found it immensely helpful and I think you will too.

Perfect book for beginners
Format: Paperback
I started designing my website using another book that covered HTML, CSS and JavaScript. I got pretty good with HTML, passable with CSS but could not get my head around JavaScript. Little code snippets that illustrated various functions just didn’t do it.
This book is totally different. Using downloadable example code and the free Visual Studio Code editor, the author takes you step by step through slowly constructing a complete JavaScript-driven website. I found writing and debugging my own code to greatly enhance my understanding of the material. And while I’m yet to get to that stage, being able to do full-stack development using Node.js and Ajax is a major plus.
This is the perfect book for beginners wanting to learn JavaScript. Highly recommended.

A great book you’ll need every day for your entire web developer career!
Format: Paperback
This book is great! I have been working on becoming a web developer and this book is a major help in filling in the gaps from other resources I’ve used. Many other resources don’t really explain why some things work the way they do, but this book explains it all! You’ll always want to have it around because it’s great to go back and reference when you’re having trouble. I highly recommend all of the Quick Start books! I’ve got the HTML/CSS, JavaScript, Python, and SQL books that I use daily! If you want to become a web developer or programmer, start with the HTML/CSS book and then branch off from there. You won’t regret it! They are all very beginner friendly and easy to understand. 💙
