MAXFLOW AIR FILTER KIT FITS STIHL 066, MS660 -- INCLUDES CAGE AND 2 FILTERS

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-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.  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.
