Im confused....are you stating that the duct is directing air at the water cooled heat exchanger on the PTU ? It is my understanding that not all PTUs have the exchanger but I cannot ascertain which do and dont, or the reason they are not universal. I have not had the opportunity to put mine on ramps and check, but will do so this week. Any ideas on why water cooling would be optional and which models or option packages may include the water cooling ?
Not sure what's confusing about it...

The cooler...yes...AKA, the heat exchanger...the "tail" of the duct splits into a "Y" shape, with one arm pointing at the heat exchanger and the other pointing toward the area where the catalyst and rear turbo sits...
This wasn't supposed to be a post about the PTU (there are TONS of posts here about the PTU), so I didn't want to hijack the thread with the topic, but I've written pretty extensively about the component on my blog, as well as on this forum. But I will post this link again for you:
