I have used K & N filters for over twenty years in different vehicles that I owned. It started with motorcycles and went to snowmobiles and now all my cars and trucks. If your planning to do intake and exhaust improvements,start with a K&N, its cheap and if the filter is all you want to do, you will see an improvement.
