Because the CAI comes with one, and the one you have now wont fit, if you want to replace the one that comes with ure cai, you need one with a 3.5 inch outlet (if im not mistaken) (aslo, the k&n filter i had in mine before i got my cai, WAY before, had a flat top, and filter sides, whereas my cheap cai filter has a small reverse cone thingy on top and filter sides, this is better for flow and filtration (in my mind)
cheap ebay cai is teh win!
