I can give you my perspective. The K&N 63 is what I have. It gets rid of a trashcan full of plastic that helps quiet the intake but also is restrictive. I am not sure how much better the performance is but in conjunction with a low restriction muffler it sure sounds meaner and faster. Here is a picture to show you how much plastic is removed.
