Wouter, theres really no wind resistance where those scoops are to be accounted for ...as a matter of fact they realized that the wind basically goes over those (on fgf s) and opening them really doesnt do anything...thats why on second gen those TA scoops were moved to a better location , up front where the cool air hits....also opening the hood at the back by the WS is also better...per wind tunnel tests..
