I took my car to fix today, notice a piece of plastic was loose by the filter and battery (the space on top of the air filter resonator. The guy told me it's the resonator or whatever I took it off but I do not recall the resonator go that high. Just want to make sure with u guys

 

Wat.

If you wondering whats missing, its the battery cover and the rad support cover.

This is what it looks like bone stock:



There is also a little plastic piece that goes from the rad support cover to the frame rail right in front of the air box. It routs air into the resonator that is mounted behind the bumper. What you took a picture of is the air box, not the resonator.
