All of the non-TRD CARb legal intakes do not have the charcoal filter. I suspect it is a device required by the mfr., but not to pass CARB smog requirements. Or, Toyota put it on to 'feel good', and it's not necessarily required- none of the other vehicles in my family have any such device, not even my mother's Volvo (and you'd think that would have it!!).
