FWIW, I just put factory new ones on, and the fit was terrible. I had to trim the front lip off, and they don't look like I want them to. I am going to end up getting Pro Caps, or something along those lines.
The factory ones were about 1/2" - 3/4" too short. Had this confirmed by members here, and two dealers. I still put them on, and wish I had just returned them...
I'm guessing they are shrinking a little too much when they come out of the mold. It irritates me that two of my friends have aftermarket, and they fit way better.
