Does anyone have the beta numbers for Purolator Premium Plus filters? I searched the archives and all I could find was single pass and multi-pass efficiencies, all of which were vague.
From Bob's oil filter test, these filters seem to have decent flow. The Purolator showed the same pressure drop as the Napa Gold, which supposedly flows well. If this filter offers good filtration as well, it might be a great bargain.
