Hey guys.. I am considering picking up some of Toyota's TRD line of Oil filters, but from the specs they provide on the filtration capabilities, it does not seem to be very impressive, unless I am reading them wrong…
They claim to have a filtration ability of 98% efficient at 20 microns. I understand Amsoils EAO filters are 98% @ 15 microns.
What do you guys think?
Thanks a lot for you feedback


------- Info from TRD ----------
NEW !! TRD High Performance Oil Filters incorporate state-of-the-art design and materials offering superior protection. The filter uses 3 plies of 100% synthetic glass/polyester blend filtration media that 98% efficient at 20 microns - that's smaller than pollen. Built with a heavy-duty pressure valve that allows oil flow during cold starts, a high temperature anti-drain back valve that retains oil in the filter to prevent dry starts, and a ported and polished backplate provides smooth oil inlet holes reducing oil restriction. For 4 Cylinder Engines.
 
I wonder if these are the same ones...

Oddly ..the alleged M1 (like) filter on the left is made like the EaO ..while the M1 I cut apart had the metal (gosh, I can't think of what to call it) "disc" integrated. The EaO was separate.

EaO on right. M1 on left
 
Gary..
I would have thought better for the TRD..

An equivalent Wix filter list the filtering capabilities @ Nominal Micron Rating: 19 ..

Not sure if this is also rated at @98% and uses the same ISO test that Amsoil also uses…

Well, the nominal is a single pass test. The multipass is considered the more accepted/reliable.

Wix doesn't appear to offer 'glass in that size. The 95% rating is only 37um

Beta Ratio: 2/20=21/37

50% @ 21um
95% @ 37um
