Can't argue with the looks statement. I do recall seeing data on airflow and filtering efficiency comparing foam to paper to K&N (and maybe others?) showing K&N with better filtering and flow than foam, and better flow than paper (can't remember if the K&N also filtered better than the paper). Regardless it was enough to convince me to replace pleated paper filters on my modern cars. Never felt a difference, though, so who knows.
