See http://www.aircraftspruce.com/menus/ap/vents.html and http://www.aircraftspruce.com/catalog/appages/nacascoop.php I have some of the small plastic ones with the screw-type opening, and they work for me. But lots of KR folks say they not only don't work, but air goes OUT of them rather than in! I think that all depends on the aerodynamics of your particular plane, and the location of the vents. My cabin is under a slight vacuum because the tail is open to the elevator fairing area, and my vents are located in front of the main spar, rather than behind it. As long as the plane is flying, I'm cool enough, and Jim Faughn showed me a neat little aluminum scoop idea that really boosts the flow by a factor of 3 or 4, so if I ever need it, I'll do that, but for now, they're fine. Be careful not to mess up the screw threads however, or make the vents removable in case they do get trashed...
