This is very true, at least in my experience. I used to keep one of the round bits of padding that Yakima sells for supporting boards, etc., around the front bar, and it was very effective at stopping the wind noise. Nowadays I use a purpose-built little winglet-like thing that Yakima sells to do the same thing -- they sell them in REI, and they work for me. Never used a fairing in twenty years of Yakimaing .the other thing you can do is wrap a piece of thin nylon cord around the bar. anything that breaks the barrier layer of air coming over the bar will stop the whistling. a fairing looks good but will not save you mpg's just reduce noise. cord around the bar is you best bet if you need something fast and cheap that will not interfere with your sun roof.
