Ok I didn't know it is that way on all cars, but now that I think about it, it does make the most sense for accuracy's sake. If the computer isn't leaning out the mixture, then I'm skeptical about the 4-5 mpg increase. Is the factory airbox really that restrictive!? If that's the case, I expect Ford would have sacrificed a little in the noise department to get those extra mpg to reach the coveted 40 mark, maybe even pass it up to beat out the Elantra.
