Some brands are now using two part numbers for the same application. The two I found now are ACDelco and Hastings, and I can't figure out the difference.
Hastings has both the LF548 and LF624. Priced essentially the same for either.
ACDelco has the PF458G and now also the PF2259G. Both are complete sets with the filter (a PF457G/Hengst E630H), cap, and O-ring. But I can't tell the difference between the 458G and 2259G. Both are labeled "Professional" and not "GM Original Equipment," but GM does this for all their filters and spark plugs, even if they are OE, which the Hengst filter is (a long time ago, Purflux used to be the OE supplier). Both the 458 and 2259 use the same Hengst cartridge and Hengst/GM-branded cap. Except the 2259 costs a couple dollars more than the 458.
Rock Auto's closeout features a Champ P2225, but the pictures show a French-made Purflux L264A. GM's OE supplier for this cartridge when these cars were brand new was Purflux. Of course, the only challenge will be just how old are these things? But if these Champs really are Purflux cartridges, then that is a very good deal! Purflux uses those wavy "chevron" pleats.
The only filters I'd use for this engine are Purflux, Mann, and Hengst/ACDelco.
