Product Description

The Max-Flow filter kit to fit the MS661 that professionals are raving about.  Cover is industrial black color.

 

High Flow, washable air filters for Professional Stihl® MS661 Chainsaws with the polyolefin HD2 filter.  Models MS661, MS660C-M, MS661R C-M.  Kit includes everything you need to convert your saw:  Two foam elements, (one green for standard cutting and one white for extreme cutting conditions), Maxflow cage, custtom backing plate and an OEm style close fit rain cover.

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 twice as long as stock air filters.  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-usable so they last longer and cost less.  Foam elements do require the use of foam filter oil (sold separately).

For more than 20 years MaxFlow filters have featured only ONE PIECE elements with no glued seams to fall apart.  No seams mean longer lasting elements with no chance for dirt to penetrate.  Don't be mislead by glued foam where gas and vibration causes the glue to fail.

MaxFlow filter kit replaces the Polyolefin HD2 Stihl Pleated Air Filter P/N: 1144 140 4400

Replacement of the air filter on Non-HD filter equipped with Fleece, Flocked or Screened Air Filters will require installation of the Stihl HD backing plate and other parts (not included).

  1. Fresh Clean Air 5 Star Review

    Posted by on 12th Mar 2018

    Loving this Filter Kit by Max Flow. The Stihl MS661 Magnums have a reputation of not so good sealing properties around the backing plate(Carb Cover)and the HD filter. Tiny particulates make their way in between and right to the carb. I'd have to check and clean between each tank of fuel. Got this kit and like always, Seals awesome and filters Great, no more dust in carb. Saves time, eventually $$, and makes the boss happy since more stumps are made!

  2. Great stock look with aftermarket added power. 5 Star Review
