There is nothing wrong with them until something is wrong with them. If you never cut and inspect your filters, you may never know when a filter has failed in some regard of either torn filter media and/or compromised ADBV.
I do not rip open every filter I have removed, but I do have more than once instance of removing either original factory installed filters, OEM branded and aftermarket major label filters and have found both torn media and compromised ADBV. Common denominator, they were Purolator/M&H derived oil filters.
For something that should be at most a one in a few hundred thousand or even million occurrence, one has to ponder about all the ones that did not get cut open and were possibly compromised also?
