I just installed the F2 Focus Cold air intake, and i want to say that i'm very happy. No problems on the install, except on the removal of all the old stock intake. I didn't feel it for the first 2 miles, but when it kicked it was nice. Tomorrow comes the F2 Exhaust. i chose to go cat back exhaust. Damn ford had to put so many bolts on the car. I removed all the old stuff and now its no nice, ill post some pics. If anyone wants one, i can get them. 185 shipped.
