That is the Resonance Flap/Manifold. Without getting technical, the flap opens or closes to provide increased torque at low rpm's and additional power at high rpm's.

It can go bad but very rare that it does. It may cause a rough idle if it is leaking or stuck. Do you have a check engine light on?

You'll need to have it checked at a dealer or indy. You need to find out what faults are set if you were to attempt a DIY.
