2013 Does fit.
 

I've got an 09 and I just put the 2013 front bumper on. The only issue with fitment is the washer fluid tank. The passenger DRL gets in the way. I own a body shop and had my guy just melt the tank a little so it molded to the back of the LED. Also, the DRL's alone are $470 each. And that's my price with a 30% discount. Not exactly worth it.

You did the opposite of what the OP was asking. So there should be no issue with the washer fluid tank when switchin 2013 bumper for a previous one.

I wander - is the washer tank on 2013 smaller, or just a different shape?

Did you buy a brand new bumper or from another car?
