The purpose of the string on some of the filters, however, remains a mystery.
Actually it's string used in the assembly process, seen on the larger Purolator made filters, though not seen as often now. I suspect it could be removed before the core is enclosed but must not be seen as a necessity to do so.

The Mopar filter (MO-090) is actually "better" than the standard Purolator; the Mopar has the thread-end coil spring bypass that makes it unique (very similar to many Motorcraft filters).
The term "better" could be if applicable depending on how important one believes thread end bypass to be. Mopar and Motorcraft use it on some of their filters but not all. Some think it's more advantageous than others. IMO, it's not that big a deal either way.
Now as for Mopar efficiency rating(s) being "better" versus the standard Classic or P1, it's hard to say. The OEM's don't give as much information as the aftermarket makers like Purolator and Wix do.
Bottom line though, Mopar is a quality filter
