Küryakyn uses only K&N and aFe oiled gauze filters in our air cleaners which, when properly maintained, are water repellent. Even so, there may be times you wish you had a pre-filter to keep bugs, dirt, wash water, or torrential downpour out of your air cleaner. Made exclusively for us in the USA by Outerwears. Water repellent, UV resistant and filters debris down to .005".
