Honda 15400PLMA02 and HPL Engine Cleaner

[Gravity_Wolves]

Why do Honda, Subaru, and maybe Toyota have media with visible holes? Toyota is the best of the three from what I see.
On the other hand it looks like the PG variants have a lot of resin in the media. Should see more fibers. Based on the pictures.
With this much dirt or whatever it is in an engine, it doesn’t seem best to dislodge it. Based on old school advice from the sludged up old engines of days gone by. Leave it alone they would say. Or tear the engine down and clean it.

Most likely so the filter doesn't completely get plugged up with soot and go into bypass mode
