1 graph proves nothing. When speaking on filters constructed in the same exact way i.e. layers, materials, a dry flow filter (brandless) will out flow an oiled filter every time. There is TONS of sceintific evidence to back this up,especially military testing that proves this. Lots of flow bench testing, and pressure drop testing. Its very easy to get confused and works in favor of K&N to talk about Oiled vs Dry becasue the construction is never consistent across the board for a true and accurate measure. Given an equal measure, dry filters out flow oiled ones everytime.
