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.

Superior product
typically take Vitamin D in large amounts to get enhanced benefits for bone strength and immune strength. this formulation includes vitamin K which enhances the absorption of calcium in your system.
These are high strength capsules with 5000 units of D in a small and easy to swallow capsule.
As with any vitamin product it takes some time for the benefits to be felt however with these products they seem to have better effectiveness than my previous brand and I find myself not having to take as much to get the full benefit.
The price is good for a premium product and the developers seem to have put a lot of thought into the formulation.

Dentist recomended
So i ordered this a while back but i wanted to use up my last bottle of D3 vitamin. I have used this smarter nutrition brand for just under a week, so it is a bit difficult to say whether this product is any better than any other brand.
But so far so good. I have no problems swallowing these pills nor any digestive problems whatsoever or any after taste.
AS far as a D3 supplement, you really feel no difference and i bring this up because i am being truly honest about this product. I started taking vitamin D3 products because my dentist, who is also a nutrionist, advised me to take this supplent for stronger bones. Also to be honest, I am 67 years young and i need all the help i can get..LOL.
I take many other nutritional products and this brand of Smart seems to have everything i need for a daily regimen. So No need to buy supplements from more than 1 supplier.
And, yes i guess i would recommend this brand to others who like to buy what they need from 1 supplier.

Good Clean Source of Vitamin D3 and K2
Size: 60 Count (Pack of 3)
I have tried several vitamin D products, some of which offered limited absorbency, so I like this product, which appears to offer better absorbency. Disclaimer: I have not followed up with testing my vitamin D levels, since I started taking this product, but I do feel more healthy, with fewer and more minor upper respiratory infections, and no flu, so far, and this product may be contributing to this. Several things I like about this product: 1) This product's D3 comes from a plant-type algae called lichen, which is a far superior source of vitamin D3, compared to lanolin, which is sourced from sheep, and used in the majority of vitamin D products on the market. 2) This supplement also includes two forms of vitamin K2 (MK-4 and MK-7). Vitamin K2 is critical in moving the body's calcium out of the soft tissues and into the bones and teeth. if you're taking Vitamin D, it's absolutely critical to also take vitamin K2. As mentioned, this supplement includes two forms of vitamin K2, which is not found in most of the other vitamin D supplements on the market. Both forms are important, so it's great that this product includes both. 3) This is a very clean product, with no harmful or inflammatory fillers. I give this product my top rating. I use this product daily, along with taking vitamin C.

Clean ingredients, easy to swallow and really works!
Size: 60 Count (Pack of 3)
I usually don’t write reviews but this product really worked for me. Hopefully my review can help someone who is looking for a supplement that really works!
I’ve been Vitamin D deficient for many years now. Finally decided to do something about it and find good clean Vitamin D3 supplement. So in 2019, I tried Mary Ruth Organic Vitamin D3 Liquid Spray first. She has a lot of great supplements and reviews. I used up 3 bottles and got my lab work done and was still Vitamin D deficient.
In 2020, New Year new start. Did a lot of research looking for a clean and effective Vitamin D3 with K2 supplement. There’s a ton on Amazon and can be quite overwhelming. After many hours of researching and reading through reviews, I decided to try Smarter Nutrition’s Vitamin D3 supplement. You just need to take 2 a day. The pills are small and easy to swallow. Finished my first bottle and didn’t get any bad reactions so I purchased the 3 bottle set because it was a lot cheaper. I was not diligently taking it everyday. I would miss some days. But to my surprise when I went to get my lab work done in June, doctor said I was not deficient in Vitamin D anymore.
Since I had great results with this, I decided to try Smarter Nutrition’s multivitamins for woman. I’m on my first box. So far so good. It has Vitamin D3 in it as well. Since I am not deficient in Vitamin D anymore, the multivitamins will provide the sufficient amount of vitamins I need daily.
