The factory Police owner's manual supplement for the 2012 Impala says to use an AC Delco PF48 (low PSI bypass filter).
Fram says to use an XG10060 or TG10060 or PH10060 (low PSI bypass filter). (This crosses to the PF48, NOT the PF64).
Wix says to use WL10290 (high PSI bypass filter). (This crosses to the PF64, NOT the PF48).
Purolator says to use the L22500. (high PSI bypass filter). (This crosses to neither the PF64 nor the PF48. I think this filter is for the non-police version, which can take the longer filter. There is no room for the longer filter on the police version since the PF48 barely fits due to the oil cooler adapter).
And AC Delco's site was absolutely no help, listing only the PF63 which is too long (and which appears to be a high PSI bypass filter).
Should this engine use the PF48 or the PF64 filter?
