Posting a cut open Donaldson filter that wasn't used because it was flooded. Made in Indonesia.
Kept it in storage until I learned how to hacksaw my filters a few days ago.
Its a drop in filter replacement to isuzu 8-98165071-0. Comparison pictures at the end.
Specs:
Outer Diameter: 80 mm (3.15 inch)
Massive rust from all the water ingestion. Anti-drainback valve is rubber.
The spring at the bottom of the filter is better than the genuine filter's design which is just a simple metal tab (next pic).
Very rusted but the filter media survived.
Left: Donaldson 47 pleats
Right: Genuine Isuzu: 52 pleats
Genuine filter's elements seems to be better constructed. Donaldson's filters are slightly thicker in terms of filter width.
Both are near in market price (Php750 vs Php800). That's roughly $13 and $15.
So in conclusion. The genuine filter has more uniform filter media. Donaldson has slightly thicker filter media with a different pressure relief valve design using a spring, which exerts more pressure. Genuine filter only has a metal tab. I do not know which design is better. But given that this filter is mounted horizontally facing the front of the vehicle, it may have different effect on the bypass setting.
