Air Vent Handle:
The standard vents are simple and work well but they do tend to let in a lot of air, which can be a problem when trying to open or fold maps, change paperwork etc. The one on the pilot side is easy enough to close with your foot but the passenger side one is a bit far away for the pilot to reach when flying solo.
I added a simple push-pull cable with a knob under the passenger door jamb. The vent can be operated by the passenger or the pilot without risk of getting jammed under the dash!
