I know this was done a while back (couple of years) at

I just could not take it at face value, so I had to cut apart one of each of these filters and see for myself. Since these filters are specific to my vehicle, it left me without any doubts. Here is what I found:
1. Both filter media appear to be the same as far as color, smell, appearance, construction, but the Motorcraft filter element is slightly longer while the PureOne has a few more pleats.
2. Both backplates appear to be identical in every respect, while the silicone drainback valves are identcal except for a slight difference in color.
3. FL-820S has the bypass valve at the backplate end of the filter, while the PureOne has the bypass located at the domed (closed) end of the filter.
4. Quality of construction is very good for both filters, fit of components is very good, and both are very clean inside the filter can and everywhere else.
I have been using both filters, but mainly the FL-820S lately. From now on until I see something else to change my mind, I will stick with the Motorcraft. They are about half the price and should do as good a job, plus the bypass valve is where Ford specifies it should be. Let me know what you think
