I know there have been a few threads on this....but I thought I'd post mine up anyway .
Install was pretty easy, took about 30 mins maximum. Just need to undo 4 clips on each side in the wheel well, then pull the liner back and reach your hand up there to push out the stock ones. I have fat hands, so if mine fit, just about anyones will fit. Someone said the bumper had to be taken off, that isn't true, unless you have Shrek hands. Make sure to turn the wheel fully to the side you are working on for maximum amount of working room.
