Just looking for some positives and negatives for either filters K&N and Screaming Eagle, reason I ask is I have K&N fitted to the Ute but cant tell the difference between it and the standard filter, just seems to be more of a hassel cleaning the fuggin thing and forking out extra bucks buying the recharge kit. I realise they are supposed to filter more crap or do they ?? and do they have better air flowing characteristics ??.....................
