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 dramaticially reduces heat soak.
- The internal FDS design forces air to utilize the entire core volume increasing effciency.
- Lower intake air temps and reduced pressure drop increase horsepower and torque.

Great Quality and Perfect for Creative Projector Effects
Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
Although designed as a shower curtain liner, I ended up using this for a completely different purpose and it worked perfectly.
I placed it behind my study window as a projection screen for Halloween videos, and the results were fantastic. The material allowed the projector image to display clearly while still diffusing the light nicely for a great effect from outside.
The quality was much better than expected, the material felt durable, and it was easy to position and work with.
This product turned out to be incredibly versatile and offered excellent value for the money. If you enjoy creative decorating ideas or seasonal displays, this works brilliantly as an inexpensive projection screen alternative.

Perfect length and actually stays in place.
Size: 72"W x 75"L (Pack of 1), Color: 1a. Clear
This liner solved a problem I didn’t realize was bothering me until I switched to it. The extra length makes a big difference—no more water sneaking out onto the floor or the curtain riding up while you’re showering. It hangs nicely and gives a cleaner, more finished look compared to standard sizes.
The material feels thicker than the cheap liners you usually find, but not overly stiff. It drapes well and doesn’t stick to you while showering, which is a big plus. The magnets at the bottom actually work and help keep it in place against the tub, especially if you have any airflow in the bathroom.
Installation was simple and the reinforced holes seem durable enough to last. Overall, it just does what it’s supposed to do without any fuss. For the price, it’s a solid upgrade and something I’d definitely buy again.

Well made
Size: 72"W x 72"L (Pack of 1), Color: 1b. Clear-heavy
The magnets hold well. The grommets are sturdy. The plastic is a bit thick and doesn't like to lie flat against the tub so it is constantly brushing you while you shower.

Exactly what they say it is.
Size: 72"W x 72"L (Pack of 1), Color: 1b. Clear-heavy
Appears to work exactly as advertised, and quality is very satisfactory, which is always a pleasant surprise on Amazon. Magnets are strong enough, plastic feels pliable and durable. Don't forget the rings aren't included.
