I too recently noticed this with the FE10575‘s available at my Walmart last week. 6 on the shelf and only 2 had decent looking louvers. The other 4 had many of them closed. The aisle has a sign saying “Smile, You’re on Camera” and I’m sure whoever was watching the cameras was giving me a close look as I had my phone flashlight out inspecting every one of them!I was at Walmart today just browsing around for a few minutes before an appointment, went to the automotive section to see if they had the updated version of my Toyota filter YZZG2 which they did not but I decided to check out the FRAM Synthetic Endurance for both my Chevy and Toyota so I opened the boxes which were not taped closed and took a peek.
FE3614 and FE3387A
On both of them there was louvers which were clearly closed and the Toyota one was the worst with a good majority of it being mostly closed. So if you are buying these filters be sure to check out the louvers before purchasing and grab another one. I did not see any other issues, no rust, metal shavings on the threads, etc but unfortunately the average DIYer probably won't even think of this.
I may for the hell of it give them a run next oil change even though I am not a fan of them, was hoping to see some used ones cut open I remember seeing some members here saying they would over a month ago not sure what happened in regards to that.

Once this OC is done I plan to cut open the first one that’s on now.
