Well I guess I will introduce myself. My name is Kenny I am 27 years old, a full time college student, and I live down in Abilene Texas. I got an 05 ZX3 with the sweet 2.0L Duratec (16K miles). I have been reading on here a while and have noticed that there are not gobs of "bolt ons" available for 05+ Focus'. I had/have about 200 bucks to drop on the black (sooo hot when clean) beast but after reading about the stealth cai I decided to go that route. The hardest part of the installation was getting that dang 3" filter on a 3 1/4" tube but when it was all said and done, boy am I happy with the results! When driving like a "Paw Paw" to quote a fellow member, It seems to pick up speed quite a bit faster with the same amount of skinny pedal. But when driving it we all like to drive it, the results of the stealth intake really shine! I recommend this upgrade to anyone who wants bang for their buck. My next upgrade is going up to 16" wheels and tires (might stay at 15" not sure) I just want some sweet black rims like the Motegi RT5's, but alas they are not available in our bolt pattern. Laters yall.
