The rattle comes as a result of the rubber being sheared off of "the metal bolt disks" of one, two or all three of the vibration damping mounts. These then no longer provide fastening much less a damping function and let the air-cleaner bang against its surroundings.

There's a reason vibration-damping mounts come as designed: To dampen vibration. Just drilling a hole and attaching a bolt straight though defeats the damping function. I've often found the heat shields (little metal cups to protect dampers from turbo/exhaust manifold heat) missing leading to earlier demise of the rubber.

These damping mounts cost almost 3x as much as stock but might stand up better to turbo/exhaust manifold heat:
