Is this question serious?
cabin filters - Mann Frecious Plus just because they've been one of the first of this kind and cheaper than OE
engine air filters - Mann on the Mini and the Porsche, OE VW on the GTI which is probably Mann (didn't look)
oil filters - see sig, Purflux on the Mini as it's OE, Mann on the GTI as it's OE, OE Porsche/Purolator on the 930
fuel filters? no idea, never looked for, didn't look for a long time/perhaps I should on the Porsche
I like the traditional green and yellow Mann boxes as well as the white and orange of Knecht btw..
