Very nice example of fully formed louvers!! ThanksView attachment 255351View attachment 255352

Apparently none of my pics uploaded, something about the image format. I will figure that out tomorrow. Sigh, stupid technology.Here are the pics.
That’s some sad craftsmanship right there…RIP Wix.View attachment 255514View attachment 255515View attachment 255516View attachment 255517View attachment 255518View attachment 255519View attachment 255520View attachment 255521View attachment 255522View attachment 255523
This last picture really shows how one have of the spiral wound louvered tube has open louvers an the other section does not.
Engine would not be in bypass but I think a blind dead chimp could randomly make a better filter.View attachment 255514View attachment 255515View attachment 255516View attachment 255517View attachment 255518View attachment 255519View attachment 255520View attachment 255521View attachment 255522View attachment 255523

i have 3 or 4 wix 10290 on my shelf in the garage , after seeing the 1st post i went out and looked at mine , mine are better but not by much , and i have one currently on my equinox , after change will be puting on a fram xg, never thought to look inside really good on an oil filter ,Zoomed in photo from post #1. On the louver in the red oval you can see where the metal was trying to open up. Some of the others show the same thing. The metal basically just stretched when the louvers were formed, and never opened up. This filter would have been in bypass 100% of the time, and depending on the size of the bypass valve could have put the oil pump far into relief at low RPM and starve the engine of adequate oil flow at higher RPM.

Been waiting for the "money shot(s)" (tube with media removed) of the louvers to comment again. Don't look that bad to my eye, imo and experience doubtful any bypass/flow issue. As I noted initially in thread post #11, speculated they could look much better than the down the center tube shots, and they do. As for rest of filter, as also noted many hecho in Mexico (vs US made) filters anecdotes show lousy quality e.g. current Bosch Premium. So for me, pretty as expected/predicted post #11.
Thanks c&p with money shots.
Just throwing some really rough numbers out, but if the inlet holes are eight 0.25" diameter holes, and if there are 200 louvers with a length of 0.25", then the louvers would need to have a width of 0.008" to match the cross section of the inlet holes.
But just matching the cross section isn't enough, because thin openings have a lot more friction for the same cross sectional area. I would guess that you'd need more like 0.05" wide louvers to match the inlet flow restriction, which these seem very far from on average.
Matching the inlet restriction isn't a very meaningful metric, but it's interesting to see such a difference.
Personally, I think this particular filter would see some minor bypassing in normal use within a normal filter change interval, and the duration and magnitude of more 'normal' bypass events like with cold starts would be increased.
More concerning is just the poor quality and unreliable craftsmanship that would apply just as much to features that aren't as easily inspected before use.
This and the fact these clowns dragged Amsoil into the mess.Hard to believe the depths this proud brand has been dragged to-crooked pleats, glue everywhere, louvers not punched out. Epic fail.
This is news to me, how so?This and the fact these clowns dragged Amsoil into the mess.
