Hay,

I am watching a audi rs4 look grille on fleabay and noticed the line 'will fit standard a4 OEM bumper ONLY'.
This seems a little broad. I have a sline model and want the rs4 honeycomb, grille will this fit my bumper?

Is there actually a difference between the stand A4 grille and Sline grille? (not including the fog grilles which are clearly different)

Thank you in advance
