The FL-500s does not seem to be plagued with the issues the FL-820s has. If every MC/Purolator filter looked this good, some faith may be restored. Thanks for the C&P!
I've used the MC 910 and MC 2017 cartridge for years now with no problems with tearing or twisting after my normal 10K OCI.
Though the FL-500s is specified for my Explorer, I use Ultras. Ultras are $4.99 each on eBay in 6 pack quantities and while MC FL-500s filters are $4.40 each in 12 pack quantities, for a $0.60 difference I have no reason to look at MC filters. With that said, these newer MC filters (FL-500s, FL-920s, etc.) do not seem to have any issues.
