You will notice some difference, but lets face it, at 390 hp stock, you'd need about a 10% increase to really FEEL something. And 10% is 39 Hp!
A good plastic, not metal, CAI will remove the factory articulated intake tube from the equation reducing turbulence and back pressure and and a much larger surface area filter to put as much colder, denser air as possible ready at the throttle body when the engine wants it.
What you will get is slightly better throttle response, fewer down shifts on hills, a general increase in driveability and an MPG maybe two. When you pair that with future additions like a free flowing muffler and a ported throttle body or go all the way to long tube headers and a torque converter, and of course a custon tune, then you will get that neck snap you wanted when you were in high school.
Depending on what CAI you go with you'll add a little rumble under the hood or a lot of ear splitting throttle noise.
I like the better than OEM look of the S&B, but a lot of the 1/4 milers on RF like the olde time Hemi hat look of the Vararam. It even has an orange option like the muscle car era Hemi air filter cover. ---->>>>preferred vendors---->>>> have both of these.
Unless you just want noise, I would avoid the open top design CAIs like K&N, AFE, Airaid, etc.
