The scoop offers little airflow, so even cooling is minimal. The slope of the hood appears to raise airflow over the scoop more than in. Sometime back I taped some ribbons around the hood and near the scoop. All airflow is more to the front of the hood, so the scoop would need to be positioned more at the very front of the insert. There is SOME airflow at the scoop location, but I dont think it would be enough to utilize as a proper ram air. I went through this way back when, when I decided to try a ram air mod, but it simply wasnt enough to work with. We suffer the same issues that the STi hoods suffered pre- '06. The scoops were enlarged for more air to be scooped in to the TMIC. I am thinking that a pre- '06 STi hood scoop size on the VX would look insanely silly.

Our best bet for good ram air is through the grill or better yet, mod through the round parking lights in the front cladding.
