I see that the Wix 51515 has a maximum flow rate of 7-9 GPM.
So does the Porsche and VW filters that the OEM number xref's to
All these filters have a bypass valve ..so there should be no "worries" about breaching the media.
The common hydraulic filters are rated for 16 gallons ..but you'll be getting a different mount and the availability will be more limited.

If that's the way you want to go, the hit up northerntool and search "hydraulic filter". They're cheap, have 3/4 NPT ports and a built in 25lb bypass valve. There is a passenger car xref for this thread/gasket too. It too sports a higher flow rate and may be easier to find in the auto parts chains. It has its own bypass and ADBV.

On your current mount, do you have pressure taps that will allow you to fit a gauge? If so, I'd get a cheap (salvage, off of ebay - there are plenty) 0-30 psi gauge and mount it upstream of the filter. That will tell you if you're at the PSID required to open the bypass valve.
Now this is opinion ..that is I don't "know" ..but my take is that hydraulic filters tend to be finer than their like sized automotive counterparts. They probably have the same holding capacity, but are typically employed in a cleaner environment that doesn't have to cope with the routine introduction of combustion byproducts. I can't resolve the flow rating difference beyond the difference between the "reasoned" matter of a hydraulic fluid being a 10 or maybe a low 20 weight. Even 10W motor oil isn't considered a 20 weight since it's doesn't have a HTHS of 2.6 (IIRC) even though it's in the 20 weight range
