Originally posted by edwardh1:quote:as in - PureOne filters meet the flow requirements of automotive applications. We test our filters per SAE specification HS806 Chapter 1, and the standard flow rate requirement that we follow states that the pressure differential (between inlet and outlet) shall not exceed 3.0 psi at a flow rate of 3.0 gpm. On the PL30001 filters, flow restriction is 0.8 psi (avg) at 3.0 gpm.
