I didn't pay attention to the orientation of the left side bag filter when I removed it. However, the more logical orientation looks the complete reverse of the what's shown on the parts fiche. The diagram shows a flat outside cover plate but my 2009 cover plate looks different. It has a protrusion on the inside of the cover plate. The inner bag filter fits perfectly over this protrusion with the gasket side (the flared side) facing outward, making a nice seal. If I reverse the inner bag filter as shown on the diagram, it's metal on metal. Could they have changed this on the '09?
