K&N Air Filter Oil - 1 Gallon Bulk Bottle (99-0551)

Maintain the high-flow performance and filtration efficiency of your oiled cotton gauze filters with this 1-gallon bulk container of K&N Air Filter Oil (MPN 99-0551). Specially formulated to work in tandem with the cotton fabric used in K&N filter elements, this oil is the critical component that allows the filter to trap microscopic contaminants while preserving optimal airflow.

Designed for easy application, the oil quickly penetrates deep into the filter pleats and remains suspended in the cotton fibers. This ensures consistent saturation across the entire surface area of the media until the filter is ready for its next cleaning cycle. This 128-ounce value size is ideal for race teams, service shops, or enthusiasts managing a fleet of vehicles equipped with performance intake systems.
