Wix 57055 C&P "Disappointment"

I would not be comfortable with those louvers. Below looks messed up too.
I don't think it is so rare with M&H..
Here is another Purolator with the same issue :

So, It doesn't look great, but the louvers mostly are opened. I am eilling to bet more oil goes through that then you think. I dount the filter was in bypass.
I posted a virgin C&P several weeks ago on an FVP filter. Louvers looked the same. Pulled off the media from center tube and posted pics with a flashlight. The filter was fine. Looks can be deceiving.
To be clear, I don't use filters with louvers. I use PG or OEM 90% of the time.

Amsoil
In: Amsoil XL 5W-30/ Amsoil EA15K13 filter. I have a 6 pack of PG PG4612EX I plan on using after. While not 100% correct bypass psi spec for my engine 14-17psi is better than 11-17 psi of the Amsoil filter. Eventually I’ll find a case correct Subaru PG EP filter when they release later this year.
Here are some pictures. You’re right that they weren’t completely shut. However some were barely open. Looking at these pictures makes me feel better about the filter performing in colder weather. Not great but probably wasn’t bypassing as much as I thought. I checked carefully after cutting the media and noticed the baseplate wasn’t glued all the way.
Yes lousy glue drives me nuts. Glued to oily sheet metal. Pff garbagio
The MGSL and CQP have the correct bypass setting and are Subaru specific. Note the CQP is the shorter version.
I’m waiting for a 12 pack case to drop on eBay for MSL
. PG EP is listed new on their site but not really out there yet. I’d take a 6 pack of those if posted.
Right? Yes, the filter certainly LOOKS bad. But as you said, looks and proper operation do not always require the other to be pristine and still function properly.
Add up all the area of the hundreds of louvers, stick 60psi on the other side, and you’d be AMAZED at how much oil will pass through that tube. Also, the bypass is 27psi on those filters, I believe. That is a LOT, so I highly doubt the reality of that filter’s performance is anywhere as bad as your assessment.
Not throwing stones, just talking @Nuclear_42 off the ledge. The can is nice and clean with no grit, and if you did a UOA and nothing was greatly amiss, I’d bet the cost of that filter your engine didn’t suffer any permanent damage above and beyond normal wear.
BTW, don’t throw those 2 new filters away, I will happily use them on my Impreza. I’ve only got about 5 NAPA Gold 7055s left. PM me and I’ll cover shipping

Lousy made, could be MUCH better. Sure.
I agree. I hadn’t gotten to the light pic yet when I had posted, but that proves our points.
This kinda feels really similar to the endless threads we’ve had where people “feel” the number and size of inlet holes is just waaaaay too big relative to the center tube thread size, and that it’s restricting flow through the filter and going to destroy their engines.
Appearance and performance are not inclusive requirements no matter how much we’d like them to be. Sometimes, (maybe after 5 gallons of home-brewed beer!) even ugly gets the job done.
it would be interesting to see a test of a filter like that, on flow rate , i have a handful on my shelf just like that one , that i wont use ,or maybe wix doesnt want the the oil to pass through too quickly or it wont filter as wellRight?

That black rubber is the sealing gasket in the bypass valve. Shouldn't be something to be concerned about, it just looks sloppy.
I was wondering what that was as I saw the ADBV separate. Thanks
They do if they are opened up well like they should be. If they looked even half choked down by looking down the center tube they get a reject from me. Solution - buy filters with holes in the center tube or an Ecore center tube.
Assuming the louvers are opened, the pressure drop across that filter when using a PD pump is probably pretty minimal. Other parts of the lubrication system will be significantly more restrictive.it would be interesting to see a test of a filter like that, on flow rate , i have a handful on my shelf just like that one , that i wont use ,or maybe wix doesnt want the the oil to pass through too quickly or it wont filter as well
Choked down louvers are not planned by design to enhance functionality. An ideal filter would have near zero dP vs flow, but of course that's impossible because of fluid dynamics physics.it would be interesting to see a test of a filter like that, on flow rate , i have a handful on my shelf just like that one , that i wont use ,or maybe wix doesnt want the the oil to pass through too quickly or it wont filter as well
It's about the dP across the filter itself due the the flow rate and oil viscosity, regardless of the dP across all the other components of the oiling system. If there is too much dP across the media and center tube, then the bypass valve is closer to opening. If the louvers are really choked down, it's going to raise the dP across the bypass valve and could make it open sooner and more often compared to open louvers that don't increase the dP.
