i thought the stock ones were made with paper like material and the K&N's have a purple'ish colour cotton material which needs to be oiled.

a friend of mine on here dyno'ed his Z with only K&N filters as the difference and got a few hp accross the entire powerband... no tuning was done either...... not bad for just filters !!
