Our latest upgrade intercooler suitable for all 1.8T models up to 200 hp.
Want to take your engine tuning to the next level? Then this 1.8T intercooler is just right for you. With this intercooler your engine is permanently supplied with optimally cooled-down air. Especially at high power levels up to 200 hp this is a must-have if you really want to have fun with it.
This means the following:
The cooler air from the intercooler means higher air density, which allows more to be burned. This increases both power and durability. The charged air remains consistently cool. You can simply replace the stock cooler with our upgrade intercooler.
This is why you should install the 1.8T upgrade intercooler:
200 hp in the 1.8T 20V engine is quite something! With that much power in the engine things get hot. But if the intake air is too hot, you will very quickly notice a severely reduced power output – exactly the opposite of what we want to achieve. Not only the power is affected, but also the engine components. Piston and co. are stressed so hard that it can lead to a major engine failure. That’s why you should definitely switch to this upgrade intercooler if you want to fully enjoy your engine and your driving pleasure.
