K&N Heavy Duty Air Filter Cleaner and Degreaser: Power Kleen; 1 Gallon; Restore Engine Air Filter Performance, 99-0638

K&N's heavy duty air filter cleaner is used on K&N's heavy duty commercial grade air filters. These filters fit large turbo diesel engines, class 6-8 over-the-road trucks, agricultural and earth moving equipment, and diesel motor homes. K&N's heavy duty air filter cleaner helps break down dirt and grime caught by the hybrid filter material so it can be rinsed out with a hose or pressure washer.
