Well the next size up is a Z456, it has a height of 101mm vs a Z411 with a height of 86mm.

It should be noted, that yes it does have a greater media capacity and volume but that in itself brings on it's own pro's and con's. Takes longer to fill and pressurise to supply oil to those much needed parts. Remember most damage is done in the first 15 minutes a car is running till all the parts warm up and expand to there correct tollerances and stop moving about as they shouldn't (imagine a supplier not putting enough packing around those much coverted BLING parts when there sent and recieving them all scratch to S&$T). Long Haul trucks and Taxis don't like to turn there motors off for a reason (anyone wonder why those cars that "had only been driven by a little old lady on sundays" die a smokey death shortly after you buy them and give them a hammering)
All filter media in them by design (as they slowly become clogged by carbon/soot/contaninants) actually become more efficient as they start to block up, at least to the point that no more oil is able to flow through the media and exits unfiltered through the bypass valve (hopefully you have changed it before this point) .
Most filter media has holes down to about the size of 40 to 100 microns (every brand is different and alot of OEM are rebages) when new. I have read that most abrassions on working surfaces are around 5 microns in depth. This is why most heavy duty Deisel motors run a Standard (40 micron full flow ) and a By-pass (5 micron low flow) to scrub the oil. The best idea is to run a Centrafugal oil filter as a By-pass filter (found on on most large Prime Mover trucks and some Landrovers TD5's)
I myself have used a Racor LFS60 (60 micron) on my 1993 Suzki Sierra since it was new and untill I let my brother have the car (that a story for another day.....and not a good one), it ran like a charm with 200K on the clock and bearly used a drop of oil. It is basiclly a remote mountable Stainless Steel mesh filter, housed in 2 halfs of a billet alluminium block that is washable with kerosine. It has a warning light to tell you when it is going into by-pass and can be opened, cleaned and reinstalled in about the same time as it takes for all the used oil to drain from the motor at each service. These are DAMM expensive I might add

P.S. My 2002 Mirage does 600km a week driving to work (95% freeway running) using stock standard oil filters and runs as good today as when I first got it. Oh yeah it has done 196K and I have done probably 110k in it going too and from work. Last set of tyres lasted 60k
