[QUOTE="mmonroe, post: 551238, member: 5564"] Exactly.. The pleating may double the effective surface area of the filter. This would reduce the intake restriction and allow the filter to last longer per given amount of dirt filtered. K&N's in general are tricky. If they are not oiled enough, they will flow great but let dirt through. If they are over oiled, they flow like crap and drip oil all over the place. In my experience, a good clean OEM filter usually will flow as good as a properly oiled K&N. More than once I have seen dyno and 1/4 times drop only to find out that the owner has an over oiled and dirty K&N - and that is a full sized one that has not had its surface area reduced. [/QUOTE]
