My TW (2005) came with what I believe is a re-usable oil filter. It is made with a screen type material, and unless damaged just clean out the debris and re-use. I know there is a paper type filter element as well. I have cleaned and re-used mine during a couple of oil changes, and still have the original, and haven't had any negative issues with re-using the filter.
In this forum topic (Technical), there is a "pinned" thread, "How to change your oil", which I found very helpful, and I think you may as well.
Can't help you with K&N filter information as I use the stock filter.
Have a good trip.
