The oiled filters are made to minimize restriction and maximize airflow. They don't trap anywhere near as much dirt and dust as a paper filter, and a nanofilter filters out even finer particles.

I'd like to see the sources that make you believe that. dirt sticks to an wet medium more than it does a dry one. my K&N after 20K miles was BLACK and dirtier vs the hundreds of other OEM filters from the past 12 years ive had. oil has nothing to do with the restriction. the size of the conical head vs. the stock one is bigger- thus allowing more flow.
