AIR FILTER MAINTENANCE COMBO KIT is the convenient way to clean and oil your foam or fabric air filter with ease. The 2 pack contains: AIR FILTER CLEANER aerosol spray and FAB-1 spray-on air filter oil. AIR FILTER CLEANER is a heavy-duty emulsion-type cleaner designed to thoroughly clean air filters without damaging foam cells, paper or glue. AIR FILTER CLEANER will remove oil and dirt from air filter elements and easily washes out with water. FAB-1 spray-on synthetic air filter oil provides unequaled protection against the elements. FAB-1’s time proven formula will not plug foam cells or migrate off of filters. FAB-1’s protective coating catches dirt and fine dust without restricting airflow. Water-resistant.
