Donaldson is a pretty big name in industrial filtration, we have a few air filtering installation assemblies at our plant in a climate controlled room, never have touched their oil filters but have heard they are pioneer of synthetic micro-glass media that goes by the trade name Synteq. Their filters are normally rated at 99% at 15-17 microns depending on the size of the filter and 90% at 10 microns.

These go for 10 dollars a piece at FleetPride. Wanted to check these out for a while to see how well they hold up in automotive applications. You can get these around 8 dollars elsewhere online. These filters are pretty heavy for their small size, the can walls are thick, base-plate is heavy, the media is supported by a beefy coil spring at the bottom end & a nice thick gasket. Bypass valve is like a hard fiber material which should seal well when submersed in oil.

Counted 48+1 pleats which includes the metal crimp seam. The media endcap lip diameter is around 70mm with a endcap to endcap height of 2-1/8" Nitrile ADBV is a bit of a buzz kill for the kind of media this carries, its normally made for industrial equipment that is rated by the hour than miles. Its pretty a beefy ADBV so might be able to go 10K miles if you wanted to.

These are 3/4-16 threaded filters, should fit most Toyota. Bypass setting range is 11-17 PSI which is about the same as the FRAM Endurance FE3614. Cut one sample for the sake of science and for your visual entertainment. Enjoy.

 
At one of the combustion turbine plants I used to work at we swapped to Donaldson synthetic media oil filters. They helped greatly for particulate counts as well as extending filter changes from the paper media filters from GE.

Looks like a good little filter there.

Love that they are wire backed. Wonder if they make one that crosses to ph 3614

Also probably used on equipment like hydraulic systems where the oil temperature doesn't get as hot as in an automotive engine.

Added some more pics to show its a direct fit. YZZD3 filter also cross ref to PH3614 from Fram webpage.

I looked up the specified vehicle/equipment, looks like their oil filter replacement interval is rated 500 hours.
