The K&N 1 gallon Heavy Duty DRYFLOW Cleaner is formulated for cleaning K&N heavy-duty commercial-grade air filters used on large turbo diesel engines, class 6–8 over-the-road trucks, agricultural and earthmoving equipment, and diesel motor homes. Supplied in a one-gallon container, the cleaner dissolves dirt and grime caught by the hybrid filter material and can be rinsed away with a hose or pressure washer to restore the filter to like-new condition.
