how come i have never seen anybody with a 2.5 daily driver that has put some sort of scoop up under the fender to funnel in oodles of air.  i get why the off roaders don't do it.
come to think of it.... i don't really see it on performance mod book, article, forum, etc.   Does it not really work?  Seems like it would be perfect for us guys looking for power @ highway speeds, trying to climb that hill.
