(looking at the front of the car)
Behind the radiator to the left hand side, under the bumper's waistline should be plastic enclosure to help force air into Rad, just modify that and shove the caf to there.
will work fine as it goes on the same principal as channeling into the rad, but CAF gets the benefit as well
from inside the engine bay, it'd come from the right, between the engine and Rad, and then down to the lower area of the bumper.
