Received my Roto-Fab CAI today, took about an hour and a half to install. Only problem was one of the foam strips on the bottom of the air box came off. Went together per the instructions and looks great.
When it came time to give it a test drive all I can say is WOW



... Gave the engine a nice throaty growl under acceleration and a very noticable kick when you get on it. Found that you need to have a little more throttle control when you wind it up as opposed to just sticking it to the floor with the stock air box. Once I figured it out it was a blast to drive. You need to really feather the throttle at lower RPMS to keep from bogging it down (hopefully the ECM will catch on and adjust).
All in all worth every penny and I am 100% satisfied so far
