This is a set of six replacement foam elements for the OS 101+102 Super Air Cleaners. Each element is pretreated with a special lubricant which traps fine dust particles and keeps them from damaging the engine. This reduces engine wear and promotes longer engine life.
Includes: 6 pretreated blue foam filter elements (30mm dia. x 9mm thick)
Note: Change elements when they're no longer blue in color (can be as often as every run if it's dusty). Two elements are used in each filter. Filter body only for #101 and complete #102 filter of OS 12CZ-11, 12CZ-R + 12CZ-Z.
