Does anyone have a comparison between Baldwin High Velocity Dual Flow vs. Fleetguard Venturi Combo? The design of the Baldwin bypass appears to be a synthetic fiber media, while Fleetguard appears to be a metal stacked media disc. But I don't know, and I can't tell if the bypass media is metal or fiber. I've seen metal disc filters on industrial equipment, and those engines seem to last forever. What I really want to know is the cold start flow rate. Also want to know how good the bypass material (fiber or metal) is. Filter doesn't do much good if it doesn't flow or gets clogged. Thanks in advance.
