That was a year ago, since used race tape (black cloth tape) to cover all the small holes in the hood long the air path.
The big hole on top of the grille at the bonnet release is the outlet for an air dam... basically a 5" 1000CFM truck intake conduit running from a mouth in the lower grill up past the washer reservoir to deliver auxiliary air to the intake, not unlike the
Walkinshaw Air Dam.
Guarantees a slightly positive charge of dense cold(er) air available in the envelope pre-throttle body across the board, ie. provides more good air than max stock flow of the engine @ just 60kph.
