I agree, the K&N is way overpriced for what you get (received mine as a gift) I would not pay simply for the K&N name. I only stated what I've read elswhere on the wizair. The best and least expensive approach is a DIY intake. There are tons of write-ups from the most basic to building you own box.
Not sure of what bug is up "Sabrewings" a$$. I guess it makes you feel powerful or some sh!t makeing wise-ass snide remarks.
