K&N Engineering 99-0504 Air Filter Oil is specially formulated for use with K&N cotton air filter elements. The oil works with the filter’s cotton fabric to support effective air filtration while helping maintain the filter element’s performance. Its aerosol spray format makes application convenient and helps distribute oil throughout the filter pleats.

When used as directed, K&N Air Filter Oil quickly penetrates and saturates the cotton filter pleats, where it remains suspended in the fabric. This helps maintain consistent oil coverage until the filter is cleaned with K&N Air Filter Cleaner. The red-colored oil also makes it easier to identify coverage during application, helping ensure the filter is properly treated.

Designed for automotive air filter maintenance, this 6.5-ounce aerosol can is a practical choice for servicing compatible K&N cotton gauze air filters. Applying the correct filter oil after cleaning helps preserve the filter’s intended filtration system and supports dependable reusable filter maintenance. Follow the filter manufacturer’s cleaning and application instructions for best results.
