when I got the car I was told they were, but seeing picutres it looks like the HKS have a yellow sticker on them and the inside is purple. is that true? I got the car for cheap because the turbo went bad (Don't know why)and the injectors. So I already bought new (rebuilt) turbos and got the injectors from COZ last week. if the BOV jacked the turbos up I don't want to do it again.
