This is about the size of a Wix 51516, or Purolator L20195 with 3/4-16 threads, but has a higher bypass setting so it is not a substitute for these. Some VW/Audis use these Mahles.
It has a respectable 165 sq. in. of media. The media measures a bit thinner, and appears more porous than most under strong magnification. This media is also one that I ran home filtration experiments on, and my results were kind of mediocre compared to a Mann, Wix, or Purolator Classic. However, this is a long life filter and is designed to be gotten dirty. In its lifetime, it probably averages good filtration after it gets somewhat loaded up.
This is a nice, sturdy filter with an interesting combination in-and-out anti-drainback/anti-siphon valve that prevents oil from being drained from either direction. Presumably, to prevent siphoning by a turbocharger's oil pump spooling down after shut down. KInd of a pain to pre-fill as I do. I use a magnet to hold open the center tube valve to pour in oil. There is no conventional ADBV disc covering the inlet holes, and the bypass valve is like a Purolator style spring and piston at the dome end of the filter.
I use this unit sometimes on our aircooled VW van. This is not the filter called for on the later model vans that use a filter from the factory, but I have a filter/pump set-up that I added on as our van had no oil filter, originally.
