I think its a great idea but I wouldnt go ram air! I have been on the boards a long time in CEG land and have read many things about it. I can rember at least two times people saying they had custom ram air that would stall the car when in netural! Ok only two cases not so bad go for it!
My personel choice would be a hood vent and KKM, vent right over the kkm either stamped in the hood or cut and added, then simply add two slots on the under side so that a rain card can be inserted if it was a bad weather day!
