it does the natural breathing, that the oem filter box prohibits...
One of the PZEV emissions criteria is the elimination (or at least great reduction) of Air, fuel vapors from entering the atmosphere after the engine has shutdown.

Perhaps I'll make a video of sounds that a Marcy Intake makes... once I get my car back.

Another familiar sound comes at idle, when the accessory pully kicks in... (i think)
Whenever I hit the AC /Fan... the intake will make a "ploonk" sound.
It comes at like 45 second intervals.
