K&N filters...yay or nay? (from a filtration standpoint)

Foam filters suck. The HKS is a foam filter.

I too just sell off the old for someone else to clean and purchase new ones. Less of a hassle.

based on my UOA's, which also measure particles that indicate poor air filtration, my K&N's work well.
