I have also been using the black Bosch "WS" filters and like them.
However, it has been pointed out in this forum that these are Purolator Classic filters.
I checked my Bosch filters against the Purolator Classics, and they are the same filters, right down to the numbers stamped in the base plate.
Now, I shop for filters based on price, between Bosch "WS", Mann and Purolator Classics.
