A six-step maintenance system designed to recharge any K&N air filter. Fully restores air flow efficiency so your air filter works like new.
K&N Air Filter Cleaner is the only cleaner formulated to clean K&N FilterCharger elements. Use of any other cleaning fluid may void the filter warranty and will most likely damage the cotton material. K&N cleaner works to dissolve dirt and old oil buildup in the filter and can be rinsed out with water.
