Previous years and generations of Mustangs had non effecient air boxes, my 2006 V6 for example. So Ford addressed it in the later model S197s. Do the CAI manufacturers just say, "Dammit, we'll just close our doors."? No, they will still try to sell their products.
Remember data is like bikinis, if you pick the right ones, you can make anything look good.
