[i M HOONIGAN]

Based on the pictures above, coupled with the fact that the airbags for the sport and non-sport have different part numbers, I'm confident that it's not a simple transfer.

If you look at the stock photos above, although the airbags have very similar shapes, they are different. The "HORN" logos on the nonsport airbag sit above the "BMW", while the horns on the sport are at the B and W line...

Bummer, but i bet BMW did this on purpose. Just like the non-sport and sport airbags on the e9x.
