It "seems" that the charcoal filters seem to be a North American thing. Europeans don't seem to have them. But, they have to deal with OPF sensors in the exhaust.
Not 100% sure though, because I believe there are a few folks in N. America that looked and didnt have them. Maybe it was an "oops" in the production line? Maybe they ran short of charcoal filters and skipped a few cars? Who knows.
