Built in Canada 2018 Demon #3135
The black filters, which are the only ones available to us here in Canada, are not a lower grade filter and are no different internally from the white ones except that they are black and do not have SRT on them. The white ones with SRT on them are appear to be only sold in the US and are not even available to us here through Mopar Parts. I did get some of the white ones from the US when a friend of mine was in the US and cut one of each of to do a comparison and found no differences between them.
These appear to be lower-grade non-SRT filters. Which is probably OK, since they have to be replaced quickly anyway.
i wonder if they are actually still making the white Viper ones...
