FL500S vs. P577066

[czego82]

I have been looking around the forums for spec on FL500S for 2015 and up F150 3.5 ecoboost. I have found few posts with old data showing micron rating etc.
It seems A LOT of peeps here and other forums recommend to stick with Motorcraft filter and some make a good point while others pick other filters.
I personally am a big fan of Donaldson filters, and wanted to see if anyone here is using P577066 on their 3.5. 6microns at 50% and 22psi bypass. Any thoughts? Tests?
Thank you

Did they give an efficiency spec at 20 microns?
