To give your bike plenty of clean air and give yourself a filter that’s easy to clean and quick to swap, pick up a K&N MX XStream Air Filter. Because with the XStream, you get more airflow, more filter surface area, and a much easier installation compared to most stock filters.

Thanks to the multiple layers of cotton filter media, each pleat on the XStream is able to grab more debris while still retaining great airflow. It does this by integrating a top cap that is a filter itself, full of pleated filter media that provides increased surface area. More surface area equals more filtered air coming in for your engine to use.

Even better is that with the removable top cap, changing filters is easy because you’ll be able to see the interior position of the filter and check to ensure that it’s properly seated . You also won’t have to mess with lining up filter mounting hardware, just put the top cover on and everything aligns itself.
