That's over stock, so they aren't going to show those high gains on a car that's already got exhaust mods done.
I'll take the other side and say they ARE worth it if you stay N/A as they help you eek out that last bit of power for your dyno numbers and sound really cool, but even with 18 whp gains over stock, you'll never feel it. Just look at that Stillen graph... the stock air boxes are super efficient 'til nearly redline (I think the stock pull on that Stillen graph is a little misleading -- it shouldn't fall flat on it's face like that at 6.5K) so the gains you see on paper can't really be felt because they're at the very end of the rev range.
