No, that was from Purolator. Everything I've seen on the UPF63R seems to state 21-31 PSI bypass, which is in line with the newer GM variable oil pump filter number of 22 PSI (like the newer LS V8s use). Still fairly high.I plan to use the dealer recommended AC Delco UPF-63R...I wouldn't use a jobber filter on any of my cars just because I might never know the quality of the product and OEM or recommended isn't priced much higher...
did you find that 36 PSI bypass anywhere besides Purolator?
