What he says is basically true. The paper elements do stop dirt better
than the K&Ns. However, they also flow a bunch less air. If you drive
your truck in extremely dusty conditions, I would use a good paper
element. Otherwise, don't worry about it. I have used K&Ns for years in
all my vehicles here in texas with no engine wear problems.
