    Comments about K&N Panel Type Cotton Gauze Air Filter:

    Bought this to replace my 2008 ninja 250r. Fit perfectly, ordered one day and received it the next day before 12pm, easy to install (with instructions), already oiled, and good air flow. Only thing was that it made my bike run a little leaner, probably because it allowed more airflow. Also, I havent cleaned it yet but it is supposed to be easy to clean.
