The article is for peugeots, but might be interesting for scoobs and other cars also..

I've just written it up here, makes for interesting reading.

As a conclusion you can the difference between a Purolator vs. a Mann & Hummel:



I also show the unit cost of the later is cheaper and provides 70% more filtration surface area

.......assuming the filtration medium is the same quality, then it certainly looks like the M&H is a winner

agreed. It could be the case that the additional filter surface area means the bypass valve opens more, and therefore less filtration is actually performed.

You can also buy M&H filters without bypass valves, but that model also comes without anti leak back valves, so you'd have to mount it vertically (using a remote filter mechanism), rather than horizontally like most OEM fitments
