Max Flow System Filter

Superior Air Filtration. Your Stihl chainsaw requires a clean air and fuel mixture for combustion to take place. At wide open throttle, as much as 58 cubic feet of air per minute is drawn through the filter and into the cylinder. This MAX-FLOW filter is constricted to run up to 300% longer, even under the harsh and dirty conditions that your chainsaw works in. The patented design provides maximum airflow while preventing sawdust and dirt particles from damaging the engine.
