will a 2006 civic si coupe grille fit on a 2006 civic ex coupe?
 

I'm looking at buying a new set of Grillcraft upper and lower steel mesh grilles and was wondering if grilles for an 06 Si coupe will fit on an 06 ex coupe

they will not. grills are not the same on the ex and si! you can upgrade to the si grill if you wanted to. looks much nicer!

How can I upgrade it if the Si grill wouldn't fit though? Cause what I'm looking at us just a set of grille inserts and it says it fits 06 civi coupe/Si. Are the dimensions different?

^^Exactly what I was thinking, but I know nothing about the new-er Civics.

I'm no expert, but from what it looks like, the width and length of the Si and EX coupes are the same.

.....in terms of the grilles at least
