I have a 2012 pre lci
I went on a mission to see if I could somehow fit the later kidney grille's onto the older cars. Here are my findings:
left side = pre lci
right side = for lci models, which I believe is 2014-2017
the LCI grille has a "bulge" that goes towards the headlights, making for an impossible flush fit
up close of the gap
interesting find.... if I remove the surround piece, it fits .... I guess there is hope?
