I ran those on stock 750 cars and on Webers.
However, last time I went to put them on my Webers the foam was crumbling, and by rubbing it would keep coming off, so I snever ran aircleaners since.
So check the foam, before you run them. Also anyone knowing where you can get fresh foam, please let us know.
The filters were also under the name Lynx and ether Warnford Design or Branford design, and maybe a few other names..
