Looks good! Getting the roof racks off will help alot. In winter you could put poole noodles or pipe insulation around the air opening to help keep in the heat when it gets colder outside. I bet it could be completely closed in winter.
You did better than I did by including your vehicle model in the thread title but one thing I've learn, however, is to post pics bigger than thumbnail sized. I know Frank Lee, in particular hates thumbnail pics (others too). I got around this by posting pic in my album and copying the bb code that is presented when you open the picture there. When you paste the bb code to where you want your pic it will show in all its glory
