It's not a simple direct swap. The hood panels are different between 2011-13 and 2014 up.
The headlamp capsules are also changed for 2014 up.
I am seeing prices of over 600 bucks for a complete 11-13 front bumper cover assembly. That's for a cover with grille and bezels along with the lower apron pieces. That doesn't include the splash aprons inside the fenders (i don't know if they are same as earlier ones) and the headlamp capsules are around 150 bucks each used.
So, none of this is inexpensive. I have both versions. I don't see any advantage with the newer headlamps. Its just gingerbread. Expensive gingerbread.
