Ive had the Chevrolet Dealer up-install the UPF48R filter both times. (aka gold letter) Its a black filter actually. I bought 3 on Amazon and did look down the bore of each of them...... not impressed with what looks like an ill fitting black ring down deep inside of it. All 3 look about the same when it comes to (not) seeing that ring around the whole inner circumference. I didnt cut one up. threw 2 in the SS trunk as loaners / spares and kept one in the garage. They really are not that much more $$ than the 48E
Normally I would also consider putting this UP48R filter in my 08 5.3 iron block Vortec LS with AFM. ....some concerns that the AFM (DOD) engines have different oil pumps or pressures and that the R filter may be a bit difficult for the pump to manage as oil pressure on the 5.3 can wane down to 22PSI when the oil gets some miles on it.
UPF48R (VS PF48) has a finer particle screen. (any proof?) Also heard it has a higher burst pressure. (any proof?) Its "made for" synthetic oil. (any proof...)?? Ooh, its seal is coated to come off easier (any proof)?? AND its also more expensive. (fact!) .
I think you can substitute with a comparable WIX and be just fine. or M1
