They have ducts that pull air from in front of the radiator. The location of the filter itself is irrelevant.
If the ducts weren't there (as they aren't for a SRI) you would be right.
As to the airbox being under the hood, the pipes are under your hood too... the air will warm up once it is in there...
Actually, metal pipes will heat it up more than plastic -- considered that?
In any case, the difference appears to be less than 5 whp on the average.
