the Ryco Z89 is a shorter version of the Z9 and has the same specs regarding filtration such as flow rates, micron, beta ratio etc. but being longer by about 40mm fitting maybe difficult in some circumstances because some 4.0 engines have a diffrent mount for the filter
a Z9 is commonly used on several vehicles especially Fords and can usually be sourced for less $10 from places like supercrap when on special
for my Wrangler the last Mopar filter was when the vehicle was brand new.
since then I've used mostly Ryco but have also used Purolator, Fram, Nippondenso but lately I've been using WIX 51515 that I've been bulk buying along with other vehicle filters from
https://www.filtermax.com.au/ as they are cheaper. I replace every 5000 kilometres along with oil
WIX 51515 is equivalent to a Z9
WIX 51085 is equiv Z89
they are mostly USA made and are often the OEM maker for Mopar and many others
