I've been using K&N for over 30 years in all motorcycles and cars. If maintained properly you will never need to buy a replacement filter. I have the recharge kit and keep the OEM filter when cleaning and drying the K&N.
K&N filters will flow better than paper OEM throughout the lifetime of the filter. I went 80k miles in my Audi without ever cleaning the K&N and there was no noticeable loss in power or MPG. According to K&N, you should be able to get around 50k between cleaning in normal conditions, but the filter should be checked to determine the proper cleaning interval.
K&N are active filters meaning the dirt particles become a part of the filter media which increases filtration overtime up to a point when it needs to be cleaned. Also, the vibration of the air/engine cause the layers of cotton fibers to vibrate creating a barrier that traps particles. Most people think because they can see through the filter it allows more particles but that is actually false. David Vizard did a K&N presentation on how K&N work. Here is a vid of Andy telling the K&N story in case you are interested in the history and functionality.
There are many K&N copies that will work fine but I refer the OG>
