With more power came more heat and for that some improvements on cooling of different fluids have been introduced.

That is a radiator for Fiat Coupe 20VT and they don't offer such for Q4, but they are very similar. It is 40mm thick and original one is around 25mm I think, but not sure. Look as a quality item, better than one Chinese for Q4, which can be seen on the net.
30 rows oil cooler
It is much bigger than original one and ... black 🙂. It is approximately two and a half times bigger that original one. It will be seen as installed in some of next posts. With such big difference in size its position on car needs to be compromised and will be at angle and not directly frontal, but such installation have been used and look to be working (it is not optimal for sure).

On 155 with original bumper doesn't have much space for big front mount intercooler, which to be "hidden" behind it. Here basically the goal was to be found off the shelf item, which to be good compromise between its capacity, for sure shouldn’t be cut front bar and metal in general and as little as possible from the bumper. This intercooler is with core size of 650x235x90mm and from initial measurements and checks look to be good solution for what is desired.
Here also will mention about one type of cooling, which is a little different than above ones. As the car will be street, as the project name suggest , it will continue to have an air conditioner ... and this time it should work. I didn’t have the chance to see it working as when I bought the car the condenser was missing and there was some cut pipes going to it! So some work in that direction will be done also. It will make installation of intercooler and bigger coolant radiator even harder and will have impact on their efficiency and they to it also, but this is how it have to be done in my opinion.
