I occasionally drive in a very dusty area and I noticed that the airflow from the HVAC system had decreased. I looked into having the SC replace the air filter but they responded that the filter should be good for at least a year but were willing to sell me one. As easy as the previous generation filter was to change, the cabin filter on my 2016.5 is behind the glove box (what a great design...)! Here's the list of steps: Tools needed: Torx T20 driver with long handle, Panel removal tool (any car store) Note: all panels are attached with clips, no screws. Remove the panel under the glove box Remove the panel that extends from above the glove box to the main display. Remove the panel on the right side of the glove box. It has a wire attached to it - just let it hang. Remove the six Torx screws holding the glove box in - 3 on top and 3 on the bottom. The bottom right one is recessed pretty deep. Remove the glove box being careful with the attached wiring. Remove the cover to the filter by compressing the clip on the right, tilting it a bit and pulling it out of the left side. Remove the old filter (I used a pair of needle nose pliers) and insert the new filter making sure the air flow direction arrow is pointing down. Assembly is the reverse of disassembly. Air flow is back to normal!
