I'm assuming that BMW used that specific type of charcoal filter to begin with as maybe a paper filter won't catch the excess vapors...
if you mean replacing the charcoal filter with a new one or paper filter thats a no because it glued onto the plastic air box

just do the removal and add air filter breathes a lot better
