MaxFlow Air Filter system for Stihl MS661 Chainsaws

Aftermarket maximum flow air filter assembly for Professional Stihl Chainsaws with the HD2 filter, Models MS661, MS661C-M, MS661R C-M. Kit includes everything you need to convert your saw: Two foam washable elements (one green for standard cutting and one white for extra dirty cutting conditions), Maxflow cage, replacement rain cover, and nut plate for use without the rain cover. MaxFlow filter elements are washable and re-useable so they last longer and cost less. Foam elements do require the use of foam filter oil sold here. Replacement of the air filter on non HD filter equipped saws or Stihlws with Fleece, Flocked or Screened Air Filters will require installation of the Stihl HD backing plate and other parts (not included).
