I don't think it's marketing if several people on this very forum have also attested to that fact. The crappy fitlers in most car suck at filtering contaminants out and restrict the airflow when they clogged with contaminants.
An oiled filter, made of a better material will filter out more contaminants and provide greater airflow. It works the same as a household A/C filter in that regard. Some A/C filters are better at filtering and cooling than others. Marketing would be if the only people claiming that fact was Perrin and NO ONE else. Multiple reviews of different air-filters, as well as posters on this forum have claimed better filtration from drop in filters and better airflow.
