Your dealership, any autobody or detailing shop should be able to give you an install price. If you just want to buy it and give the install a try you can get it off eBay.
Nick, I would check around at window tinting, detailing businesses. Thats what I did and having it done makes getting the bugs off the front so much easier on the paint. The product that was put on was 3M Scotchguard, came with a 5 year warranty. Apparently if I have a problem with it any other authorized dealer will repair it. Good luck!
