Stihl OEM Air Filter (Fleece) for MS171, MS181, MS211 Chainsaws 1139 120 1602

Replacement OEM air filter from Stihl. Keep your chainsaw running efficiently with a clean air filter. This filter has a fleece (flocked) material on the surface that picks up fine particles of dust. They filter very well (which is a good thing), but tend to ice up in sub freezing conditions. We recommend a nylon mesh filter for frozen sawing conditions. These filters can load up quickly, so keep a couple of spares handy.
