How WELL do Fram Ultra's flow ? Good enough seems to be the standard answer, as Fram makes no claims about flow in the Ultra line.
They DO, however, advertise flow in their RACING filter line up ... from Fram's website
" ... Low-restriction racing media designed for high oil flow. The media features 94% efficiency @20 microns for excellent engine protection. "
And, where flow is optimized, filtration is compromised. Not sure there is any way around that.
