K&N Recharger® Filter Service Kit. CP-99-5050
K&N Filter Chargers® use a specially formulated oil to attract and suspend dirt to the cotton-gauze filtration surface. Over time, dirt accumulates on the filter and airflow can be reduced. This is where the K&N ReCharger® Filter Care Service Kit comes to the rescue. Included are a cleaning solution and dirt-attracting oil, both of which are formulated specifically for K&N's cotton-gauze filter media.
