I really thought about adding a hood scoop to my D150 but ended up putting a Spectre ram air system on instead. Its a nice chrome air cleaner with two snorkels with tubes connected to the air source, I put a 4 inch hole in the radiator support on the left side added a screen and now it pulls fresh air from behind the grille on the other side rather than make another hole and be close to the battery I just connected to the factory air intake box which pulls fresh air from under the turn signal.
