MaxFlow® filter kit to fit the Stihl® MS500i is now available  with everything you need to convert your saw:  Black all season cover, Maxflow® cage with grey lid, two high flow, washable foam elements, (one green for standard cutting and one white for extra dirty cutting  conditions or your option). The all season cover has the integral rain and brush baffle. The best chainsaw Stihl® has ever built has a high performance upgrade!

Engineered from a clean sheet, every part of this MS500i kit is a new patent pending MaxFlow® design.  Using the factory cover would have seriously reduced airflow so we developed a totally new design that maximizes airflow through a full size MaxFlow element while still keeping the functional lines of the original. It fits perfectly using the stock alignment locations and mounting knob.  Sure, it costs a bit more, built it is purpose built to give the MaxFlow® performance you have come to expect. The rain and brush baffle or cylinder shroud will need to be customized to suit each users cutting situation.  Please read these instructions on how to modify the baffle.  A video is here.
