I am ready to ditch my K&N stock replacement and throw in a real filter. Swabbed my intake hose the other day and was disgusted. Does anybody know what kind of flow you can really get with an afe Progaurd 7 stock replacement?. Compared to to a stock paper? K&N drop in? I want better filtration but do not want to sacrifice airflow. I debated on going to the whole intake assembly but don't know if it would be necassary with my set up and my future ingector upgrades (mach 1). Would some one give me some guidance on this subject please. It boils down to cost. Keep what I got. Spend $100 bucks on a filter or spend $250 on an intake.
