I got the size from Bav. Auto. The driver's side fits perfect and the passenger side, at rest, sits with the right tip almost touching the rubber, so I don't think I could of gotten them any bigger. I noticed when I was looking at some other brand, similar to the Icon's, that each year was different and they didn't even list 05 xi's in the fitment guide. If I was not so lazy I would go take a pic and post it.
It was pouring today and the blades worked much better then OEM.
