I have a few of these, and would like to know how they compare to the 015s, as used in the B21FT, Audi, VW, etc.

They aren't in the 1992 Bosch catalog, so they must be pretty old. I got them with a bunch of K-jet stuff years ago, from a shop that did pre-production turbo R&D for Volvo in the late '70s.

I ran them OK in a '76 240 in the mid '90s, but wonder about their orginal application, and swappability with the 015s.
