Naca duct headlamp lid directing air into an airbox definetely works. Moves a lot of air without disturbing air flow over the hood much.

yeah NACA ducts have been around for ages and do work, I guess it's not so bad since it took care of most of the crack on the hood and hot air comes out while at idle...

it's your call...it wont work like an extraction hood but cold air does go in right on the turbo, not sure if it's good or not I'm not an expert. On idle and traffic it works great you can just see the heat raise, even the strings were going up but once your start going over 40mph the strings start to go in.

Tommorrow I will do a couple of runs with the vent covered and with it uncovered and we will see what the results are

If I can find one, I think I will get one and try.
