Odd noise coming from air filter

There is also a vacuum hose on the back side of the air hat just to the side of the throttle body. If it has been removed there is a chance someone forgot to put it back on.
Also make sure its sitting correctly and check to make sure the gasket between the throttle body and air hat is still there and in good condition.
