Most interesting. I paid $132 for mine on ebay, delivered from UK, and didn't get all of that stuff. In fact, I'm a bit confused. I'll post a pic of what I received, but then again, I'm not quite sure what that is.
Edit: OK, this is what I received. The box contains the primary 3 throttle body filter, a smaller end of tube air filter, a box of SS ring clamps & instructions and a long control rod type of gizzi, about which I'm sure the installation instructions will explain.
