I'm quite interested in anything Mann HU6013z since my GTI EA888 3G uses the same,
but I'm suprised to see the Fram has more pleats. I remember reading about Mann filters
having more pleats than others (don't remember which) several times in the past, but that
could have been air filters mainly.
While I'd love to see some data I'm convinced Mann filters perform well. VW/Audi would
have chosen a different supplier otherwise. I feel comfortable with a Mann whether they
provide data or not.
Btw, do Mann make it with white filter media now? I'd bet it used to be yellowish. This is
a Mann provided image and it's supposed to be a HU6013z:
Some years ago I had a Mann HU6013z in my hands, but I can't remember for sure if it's been white or yellow.
Since then I had oil changes on this car done at the dealer.
