IMO dont use a k&n. they really do let in more junk than a foam filter. when i bought my foreman it came with a k&n, i switched to a UNI and have seen 0 diffirence in preformance. with the UNI its piece of mind that im getting the best filtration, and not letting larger particles of dirt threw like k&n dose.
its proven that k&n has more airflow, because it dosnt filter as fine as foam.

Here is an interesting article where they compared various air filters. Granted, it is for a duramax truck, but it is the only independent test of assorted air fliters using ISO testing equipment that I have come across.
In a nutshell, all the aftermarket filters flowed better than stock when clean, but after a little bit of dust was introduced the stock filter flowed better. The stock filter also let the least dirt pass through.
