MaxFlow Air Filter for Stihl® Chainsaw Models MS440, MS440R, 044, 044R, 044RZ. High flow, washable kit includes everything you need to convert your saw: Two foam 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.
This helps your saw breath better 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. Foam elements do require the use of foam filter oil (sold separately).
For 30 years MaxFlow filters have featured only ONE PIECE elements with no glued seams to fall apart.
Compatibility notes.
