Agree whole-heartedly with the statment above.
Flow is not an issue on just about any mass market filter from any brand name. They all will flow WELL more than the engine oil pump will ever push. As a mass generalization, probably on a factor of 2:1. So quit worrying about flow. How the PureOne ever got this undeserved reputation for restriction is beyond me; it's an internet myth. Somewhere here (cannot find it at the moment) there is a response from an engineer with lab data showing the filter more than adequately flowing, even past what a high-performance Corvette needed at full WOT rpm. Folks need to get over this. Any brand name filter will flow more than well enough. Period.
Further, there is a great deal of data to show that as long as the OEM specs are met (min flow, min efficiency, size, dP, burst pressure, etc), then the filter is really moot. I am not saying a filter is unimportant; do NOT misunderstand me here. I am saying that as long as you meet minimum safe OEM criteria, any filter will do the job well enough to support a very long OCI. You can buy a "better" filter, or even what you believe to be the "best" filter, but you'll not see any significant shift in wear one way or the other, in normal use. I would challenge anyone to prove otherwise with real world data or a credible SAE study. There is simply enough variance that the small nuances of filtration get lost in the noise. The only time you would see a true shift in performance is either to GREATLY extend the OCI (thereby pushing a lessor alternative to the point of failure), or gross system negligence where a premium product would not avoid failure, but perhaps postpone it's arrival by some undetermined amount.
There is no "best" filter that can be covered by a blanket conversation. However, there are many good products that will more than fill the need. What you "want" past that is up to you, but don't for one second believe that your best is always the best. The only way to PROVE what is "best" for any particular application would be to do a LONG, CONTROLLED series micro-analysis study. (See my article about normalcy on the home page).
