You will have to replace the three rivets on the wheel well's underpanling. I stopped by the dealership and picked them up on way home from work.
The Grommet is redesigned and has a more generous netting around it. The original part has really thin netting and gets clogged with accumulated algea-type slime. (You can clean original one off and it should work again)

If you can change a tire, have a set of Torx Screwdrivers and a set of metric sockets you can do this. I did it my apartment's parking lot.
Jack the car up, remove the tire. Start taking off the underpanneling. Just work patiently and you'll be fine.
I wouldn't pay the dealership to do this when they charge $120 an hour on labor (@ 3hr job by their books). A local mechanic can probably do it much cheaper if you are uncomfortable doing it. Just print off the DIY and bring them the parts and they'll do it for you.
