That's just not true, just because it was on the internet doesn't make it true.
K&N filters filter just fine and filter better as they get dirty.
Whatever you read was probably planted by someone backed by a paper filter maker.
It's absolutely true. I'll find the links later. At least two people have done completely independent testing.
And you could just apply common sense. A K&N has fewer pleats and therefore less surface area than a normal paper filter. So how do you think it restricts flow less? By having bigger pores. K&N themselves say that the filters are 98% effective. But guess what.. a quality paper filter is well over 99%. Sent from AutoGuide.com Free App
