2011 Prius Cabin Filter Poor Fit
The replacement cabin air filters seem to have a very loose fit. Is this 2011 Prius model supposed to have a plastic frame that the cabin filter fits in ? Looks like it should have some sort of frame to create a tighter fit. The replacement part, Fram CF10285 is the part # that I'm currently using to replace the mouse-chewed ones. I appreciate any info anyone might have about this.
