There's some curious distinctions between the filters. The 51356 is a finer filter. In Wix it has a broader span on the bypass valve. 8-11 while the 57 is just 8. Fram recommends the PH5343 which is identical in every way to the XG7317 ..and the PH5343 is a replacement for many filters that share the 7317 number from other mans. Both Frams (5343/7317) have a higher bypass setting - 13
It might suggest that fine filtration isn't desired or required in the Polaris application, but FULL filtration is.
