K&N 99-0638 Heavy Duty Dryflow Air Filter Cleaner - 1 Gallon

K&N 99-0638 is a high-capacity, professional-grade cleaner formulated specifically for restoring heavy-duty commercial air filters to peak efficiency. This specialized solution is the only cleaner recommended for K&N hybrid Dryflow filter media used in high-demand diesel applications. It is engineered to penetrate and dissolve the stubborn soot, road grime, and particulate matter common in industrial environments.

Designed for large-scale maintenance, this cleaner is ideal for servicing filters in Class 6-8 over-the-road trucks, agricultural machinery, earth-moving equipment, and large diesel motor homes. The formula allows for a simple soak-and-rinse process, effectively lifting contaminants so they can be washed away with a standard hose or pressure washer, returning the filter to like-new condition.
