Like stated above unless you do something to the engine to allow it to be able to use the CAI for it's intended use, it won't benefit you much at all.

You are looking at porting and polishing the heads, matching the intake and exhaust gaskets, increasing piston size or stroke, and other things. Then you can get a CAI. You would probably also need an exhaust to match so that flow can continue unrestricted.
