K&N filters aren't stock but do you know what they look like vs. a stock filter? Just because the sticker is on there doesn't mean that's what's inside (previous owner could have kept it). The stock ones are made of paper and the rubber base of the filter is orange and with a black cone at the top of it. The K&N has a black base and has a metal screen around the outside of the filter w/reddish cotton fiber on the inside. It will also say K&N on the flat top of it.
