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.

and the K+N' s cost a s#$% load more! I can't believe how much they get for those dirty, inefficient things. I'm glad I went with dry paper from the beginning on my Super.

I saw a test on eight air filter years ago. Of the eight test they did on the eight different brands of filters, K&N came in 7th or 8th in every category

But they have the best ad agency
