Air Filter Oil

Keep the K&N Filtercharger air filter in your dirt bike or ATV operating smooth by cleaning and reapplying the proven K&N Air Filter Oil.

K&N Air Filter Oil is the only oil specially formulated to work in combination with the cotton fabric in K&N Filtercharger elements providing a superior air filtration system. When used as directed, it quickly penetrates the filter pleats, where it remains suspended in the cotton fabric. Saturation is maintained until the element is cleaned with K&N Air Filter Cleaner.

The K&N Filter charger Air Filter Oil comes in an aerosol spray can for quick and easy application that penetrates into the Filter charger cotton element.

K&N Air Filter Oil comes in a 6.5 ounce can.
