Filter Cleaner - 1 Gal.

K&N Filter Cleaner in a 1-gallon jug is the professional-grade solution for restoring reusable air filter performance and longevity. Designed for automotive enthusiasts and mechanics who maintain high-flow intake systems, this cleaner removes accumulated dust, dirt, and debris that reduce airflow and engine efficiency over time. Whether you're running a K&N high-performance filter in a daily driver, track car, or off-road vehicle, this cleaner extends filter life and maintains peak air intake flow without requiring replacement.

The formula is engineered to dissolve trapped contaminants while being gentle on the filter's cotton gauze media and synthetic backing layers. The included spray nozzle allows precise application without oversoaking, reducing dry time and preventing damage to delicate filter construction. A single gallon provides multiple cleaning cycles for standard intake filters, making it economical for shops and serious hobbyists who service filters regularly. The cleaner works effectively on oiled and dry-type filters, cutting through grime that normal compressed air alone cannot remove.

Mechanics and engine builders trust K&N Filter Cleaner because it restores airflow without degrading filter seals or damaging the media substrate. It's compatible with all K&N reusable filters and works equally well with most aftermarket intake systems from leading manufacturers. The 1-gallon jug size makes storage practical in any shop environment, with the convenient spray nozzle enabling controlled, waste-free application. Regular cleaning with this product keeps your high-performance intake system operating at design specification, supporting optimal fuel economy and horsepower delivery.
