The MaxFlow® filter for the MS500i was developed and tested for nearly two years. Initially released as the "summer" version with a partially exposed filter element, the current "all season" version has an integral brush and moisture baffle that fits neatly under the factory cylinder cover. In many cases, user modification to the cylinder shroud cover or baffle IS REQUIRED to prevent contact between it and the MaxFlow cover.
Use of MaxFlow® products indicates acceptance of user responsibility for equipment compliance and any non‑stock modifications. View full disclaimer Copyright © 2026 MaxFlow Chainsaw Filter Upgrade for Professional Stihl Users - All Rights Reserved.
