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.
