K&N Air Filter Cleaning Kit: Aerosol Filter Cleaner and Oil Kit; Restores Engine Air Filter Performance; Service Kit-99-5000, Multi

Designed to restore the performance of your K&N oiled cotton air filter, the K&N 99-5000 Refill Kit includes a 6.5 oz. oil spray can and a 12 oz. Power Clean spray bottle. Power Clean industrial-strength degreaser helps dissolve dirt, old filter oil, and other particles that clog the filter, allowing them to be easily rinsed away with water. When used as directed, the included air filter oil remains suspended in the folds of the cotton filter material, allowing for excellent contaminant absorption.
