      Correct me if I'm wrong and please comment.

      It seems to me that air from both the engine compartment and from the fresh open-air side goes into the intake. Poke around with your fingers, including from underneath to confirm. As engine-side air is hot, I wouldn't have thought it was wanted.

      Is there a valve that chooses where the air comes from?

      I can confirm it does on my '15 as well and there's a lot of different opinions as to why that is so I won't offer an opinion on it.

      I know this fits the non facelift mk7s but make sure to confirm it also works for the 7.5s if you do decide to get one.

      Depending on the explanation I'm thinking of heat-shielding the duct, filter box & anything else in the flow path up to the turbo to reduce radiant heat. The benefit will be minimal I know but such tweaks are additive over the long term.

      I have googled and found that the way it is designed is to ensure air gets through if there is a blockage due to snow. As we never get enough snow to worry about in South Australia, maybe it would help a little to use what is described as a "Rear Air Intake Trim Plate"

      Maybe, the hole on the underside is to allow bugs to drop through before they clog the air filter?
