2015 Focus Rear Diffuser Question

[Beast535]

Hi There

I have just bought a 2015 Focus Titanium and just wondered if the zetec s diffuser can be swapped over onto the standard bumper or I need the whole thing? Looking at pictures it seems I can take the standard black bit off the original and replace it with the zetec s's, but I wanted to check first.

Apologies if this has been answered before, but all the searches of the forum just seems to bring up the fiesta and earlier focus procedure.

Many Thanks
