If you have not heard of do88 it is likely because they are located in Sweden. They supply hoses and cooling packages to Koenigsegg so their stuff is engineered to a high performance level. They just released an upgraded cooling and airflow package for the Porsche 991.1 and 991.2 Turbo models.


Included is what you see pictured here (inlets not pictured):


Upgraded hoses, Y-pipe, intercoolers, and inlets.

You can see the size difference in their intercooler offering vs. the OEM designs here:


So how well does this upgrade package work? Well, we have some data although it is all first-party:


An appreciable difference for sure and a pressure drop of 2.54% which is great for efficiency as the turbos are not working as hard. That means less heat.

The package retails for $4227 and it will be interesting to see if anyone in the US tries it out.
