While one might think this, think about how long a typical gas motor lasts... cutting a few miles off that expected life doesn't really show itself... take a diesel that pushes A LOT more air and one that someone expects 300k out of... cutting that to 150k hurts...
It is real easy to market a product... even one that is marginally good.
I still think the issue with my K&N was due to the poor seal more than the quality of the filter media.
