The air intake is already in front of the engine compartment, so it's getting cool air directly from the upper grill.

You may want to look at TDIclub.com for good information about the VW diesel. They do not recommend aftermarket cone style filters as the factory filter is already very good and free flowing. I have seen where some owners will add a second duct to the air box.

I have tuft tested the hood/windshield/A pillar/side window area send found the air is flowing forward at the base of the windshield. The wipers are in a “recirculation bubble” so nothing is to be gained there, at least on the Golf.

I suspect he is using E-Off pulse and glide to get those astonishing numbers. I do not recommend doing this in a turbo diesel except as an extreme mpg stunt. You could probably achieve those numbers in a totally stock Fabia Greenline. I plan to keep my car a long time and I would worry about turbo issues among other things.
