K&N Air Filter Cleaner is the only cleaner formulated to clean K&N Filtercharger elements. The use of any other cleaning solution can void the filter's warranty, and quite possibly could damage the cotton material. K&N Cleaner works to dissolve the dirt build up and old filter oil, and can be washed away with water. Complete instructions on bottle.
NOTE: Do not use on polished or anodized aluminum.
