NWP Air Filter (Fleece) for Stihl 017, 018, MS170, MS180 Chainsaws (Replaces 1130 120 0800)

Replacement air filters from NWP. Keep your chainsaw running efficiently with a clean air filter. These filters have a non woven fleece material (also known as flocked or felt) 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 using a nylon mesh filter air filter when sawing in frozen conditions. These air filters are oil-less. Filters can load up quickly, so be sure to have a couple of spares handy.
