Re: 2012 Impreza Leather seats in my 5-speed manual 2013 Crosstrek?
Actually, the XV does not have airbags in the seat. All of the side curtain airbags are in the trim in the pillars which is the same for the Impreza. Take a look at the pillars of your car and it's actually marked where the airbags are, they sit under the headliner just above the marks. I would imagine that they would bolt in just fine.
Edit: see post below. I was sort of incorrect! Sorry!
