Just make sure the one you get is an actual "Kia" accessory.  Kia has made
custom-made these with the hardware and such already up there.

You can buy some after-market ones, but you may have to drill some holes, or
do some other things you may not want to do with your Kia.

While they do cut down on fuel efficiency a little bit, in bug areas
(Minnesota is a great example in the Summer), it is hard to imagine vehicles
without them - the bugs are so thick, especially at night.

Hope this helps.
