[ZR1] AC Delco UltraGuard UPF48R Oil Filters Available
C6 Corvette ZR1 & Z06General info about GM’s Corvette Supercar, LS9 Corvette Technical Info, Performance Upgrades, Suspension Setup for Street or Track
I have a 2008 LS3 and would like to use this upgraded UPF48R oil filter in place of the standard PF48 oil filter. It is my understanding that the
UPF48R is a direct replacement for any vehicle that uses a PF48 as standard equipment. I trust that the thread size and diameter is exactly the same as the PF48 (please verify). Also, I believe that the PF48 filter has a bypasss valve inside the filter instead of integrated in the vehicle. Do these UPF48R oil filters have this bypass valve as well? It is quite visible if you look inside the oil filter. I want to be careful when I deviate from the specified oil filter. I am sure that you understand.

I can certainly understand your concern. Yes, the UPF48 is a direct replacement and has all of the features of the stock PF48, but with better filtration, etc.
