MaxFlow Filter (MS500i)

MaxFlow Filters are the ONLY aftermarket filters that are 100% USFS approved. Don't risk being shut down on Forest Service property.  Reference the (MSE) SAG HS type A. 

MaxFlow air filters trap the smallest particles while flowing full CFM for up to 30 times as long as stock air filters.  This helps your saw breathe better during prolonged use in adverse conditions, resulting in smoother running and more power.
