Depends on the grille.
When I first got my Vento front, it had a horrific debadged late grille, and I put the GTI grille badge on it in an attempt to make it look less horrific.
When I got my facelift and then my early grille.... The space between the slats was too large for the GTI badge to clip in (not that I wanted to), and the early grille too small.
