lunarc- I have a focus sport intake and love it. My car definately pulls harder down the road and the noise is so sweet. I mean it's not a big power gain or anything but it's a lil something to tide you over until you get more mods. The heat shield that comes with it is also a nice touch. Plus it's a pretty good buy and a realllllly easy install. It took me and a friend around 30 minutes.
Curent Mods: Focus sport cool-flo intake, B&M short shift kit, Cobra fender badges
