Unfortunately, I agree with the sentiment that the quality has slipped, they are often usable, but the construction should be checked for each filter and can no longer simply be trusted.
I recently bought a group of Wix 57145 filters from Rock Auto that were labeled Made in Mexico. The louvers in the center tube were basically closed on all 4 filters I bought. See sample picture attached.
I’ve bought several flavors of Wix filters over the years, and never had an issue before this last group. I still have a few Napa Platinum from the Made in USA, round holes in center tube era that I’ll definitely use.
