If you pull off the sound insulation you will see the hood has a V shaped reinforcement from the back edge of the hood running forward to the point of the V. An open area exists in the center back suitable for a cut for the extraction scoop. True, it is blocked by the S/C, but only the hood skin would need to be cut. Dragon Bob did this. Bob? Comments?
Unfortunatly, this area becomes a high pressure point at speed. For low speed it should help alot.
