On your journey to getting the most performance out of your 2.0T powered VW, having to invest in a multitude of upgrades such as tunes, exhausts, and possibly even turbo upgrades is inevitable. While these performance parts are absolutely necessary to increase the output of your car, they all bring a very critical and undesirable factor with them, HEAT! Increasing the boost, fueling, and timing all increase the temperature of the air going into the engine and as we all know, the hotter the air going into the engine is, the more it's robbed of its full power. Enter the ARM Motorsports FMIC Kit.

The ARM Motorsports GTI / GOLF R Intercooler upgrade has the ability to cool off those high IAT's tremendously, but how well does it actually correlate to unlocking more power out of the 2.0T? Well, fortunately for everyone we had a customer send in some very impressive dyno results after installing the ARM FMIC Kit on his MK6 GTI that can answer that question.


  • The car was equipped with a DSG transmission
  • Starting Modifications: Catless Downpipe, COBB Stage 2 OTS Tune
  • 88 Degree Ambient Air Temperature (quite toasty)
  • Runs were performed on a Mustang Dyno


The GTI's first dyno run was done on COBB's standard off the shelf (OTS) Stage 2 map with the stock intercooler. This produced a peak output of 195whp and 210wtq. After installing the ARM Motorsports FMIC the car was dynoed again. This time the total output was 225whp and 256wtq, a massive 30whp and 40wtq increase!


But that's not all. After reviewing the dyno charts we discovered the ARM FMIC had produced even larger gains of 54whp and 60wtq over the stock intercooler above 6,000rpm. While this isn't the area of peak power, it will most definitely improve quarter mile times and can also be felt from the driver's seat.


Seeing the largest increases in power and torque near the end of the rpm is to be expected due to the dynamics of the engine. Such that as the engine spins faster and is under load for a longer period of time is when the stock intercooler begins to lose it's efficiency. Looking at the graph of the stock intercooler you can see the power and torque starts to decline sharply around 5300rpm. The power and torque curves with the ARM intercooler installed held much stronger to redline. This is where the ARM GTI FMIC really shines, lowering IAT's in the upper rpm range by getting the freshest and coldest air to the intercooler on top of the radiator assembly right up front. 


Some things to consider. The baseline Stage 2 run (stock intercooler) of 195whp is a bit lower than normal. This could be due to the type of dyno which was a Mustang dyno, traditionally a lower reading dyno than some others. Also the ambient temperature of 88 degrees Fahrenheit is a bit higher than most runs are typically done at, and the humidity was unquestionably high also (Florida car). In general, the hotter the ambient temperature is, the greater benefit you will see from an intercooler upgrade. Also, the more power your car is making before the FMIC upgrade the more of an effect the upgrade will have. Meaning if you're running a car that is completely stock you may not see a full 30whp/40wtq gain like you might expect on a Stage 2 car with exhaust.

Overall the ARM FMIC Kit produced some very impressive gains. 30whp/40wtq is huge considering that is about what you would typically gain from a downpipe. The intercooler upgrade made not only a nice jump in power and torque, but also will help make that power more consistently. By keeping IAT's down, the fluctuating weather temperatures will have less of an impact on the performance of the car.
