MaxFlow Air Filter Kit for Stihl 500i Chainsaws

High performance air filter kit from MaxFlow. MaxFlow air filters trap the smallest particles while flowing up to twice as long as stock air filters. This helps your saw breath better, especially during prolonged use in adverse conditions, resulting in smoother running and more power. Unlike pleated filters, MaxFlow filter elements are washable and re-useable so they last longer and cost less in the long run. MaxFlow high performance air filter systems will increase you chainsaws airflow from a stock 89 CFM (cubic feet per minute) to an astounding 135 CFM. This increased airflow should give your saw an extra boost. These kits come with almost everything you need to get going (except the filter oil), including a filter cage, filter cover and two filters: One 60 pore green filter for standard conditions, and one 80 pore white filter for extremely dirty conditions. These filter systems require the use of foam filter oil, unlike the stock system. MaxFlow air filter systems are USFS approved.
