Hasn't this been out for awhile?

 

What kind of power gains will i get with it? does this replace the plastic air box? Will I here the whine of the supercharger more?

 

this just drops in as a factory filter replacement and gives very little gains, a real gain comes from getting a real intake that replaces the entire intake piece including the filter box. And no whine unless you do the airbox mod.
