I've had them for almost 2 years now, no problems as long as you maintain them properly. You're going to find something negative about every product if you look hard enough. The problem with these is that people don't re-oil them properly or damage the filter somehow.

That's not very scientific, and if there is less flow with the K&N, there would be less power. It's proven on the Dyno, not a makeshift shop vac test, which you're not suppose to do by the way since it could damage the filter element.
