The air dam blocks the lower air intake and it appears that the upper grill is open. The engine draws air from one of the quarters of the upper grill, is any of the rest of it blocked? On our Legacy there is a gap of several inches between the bottom of the bumper and the front/bottom of the radiator which is open and is probably a larger area than the entire upper grill. Have you modified that region at all? It seems like on the highway, with the lower grill blocked, air going in the top grill would tend to be pushed down the front of the radiator and exit out under the car. So on the highway it might be beneficial to close off that lower gap a bit, which would increase the pressure between the radiator and the grill, causing more air to go through the radiator, and possibly less through the grill. On the other hand, it might not be such a good thing for cooling at lower speeds.
