Re: Wind diffuser
I think the question was "does the Chrysler one work?". I have one and I don't think it works well. Both driver and passanger will get blown around. Does cut down on wind in the cabin but not much on your head.
The full mesh design in the 2nd response would be my choice. The others look like they work just like Chryslers windscreen except you get nice pics, at a price.
My two cents worth...
