There are some that are functional Ram Air CAI kits but the difference in the price doesnt usually justify getting that with the hood shown. Even the Shaker kits do no better than a standard aftermarket CAI. On my old 2007 I had a JLT CAI with a tune from Bama tunes and got a gain of 38 rwhp. Not bad for $750 and very easy to install.
