This is the same CAI that Ford Racing sold and it's the same model that was used with the Shelby GT S197 in 07, 08, and 09. It will work with the stock inlet elbow and it will work with the Steeda high flow elbow. It will work with other elbows but I can't guarantee which ones.
This CAI is brand new. I've used one in the past and can say that it works and looks great.
