Twin Air Foam Air Filter KTM 50SX 01-08

fused outer and inner elements prevent dirt and grime from being lodged between layers.  unlike twin air, this can be a problem with two-piece designs.  trapped particles can restrict airflow and if dirt works its way into your engine, a pinhead sized granule will gouge your cylinder, piston and rings.
thick, flat foam, greaseless sealing ring ensures maximum contact with your airbox while acting as a breathable gasket for increased air passage

• coarse open-pore foam catches airborn dirt, grime and sand
• fine open-pore inner foam acts as a second filter to trap the smallest particles while ensuring maximum air passage
• exclusively formulated adhesive withstands repeated cleaning.  even with harsh solvents or gasoline
• twin air filters are slightly smaller than stock filters to increase air space around the filter and improve circulation
