Description
Overview:
The Filter Frame for Stihl MS171 (MPN 1139 124 0500) is a genuine Stihl OEM component for the air intake system on Stihl petrol chainsaws. Made from durable, impact‐resistant moulded plastic, it securely locates and supports the air filter element so it seals correctly against the airbox. This prevents dust and debris from bypassing the filter and entering the engine, helping to protect the cylinder, piston and carburettor. Designed specifically for the Stihl MS 171 and MS 171 C platforms, it matches the original mounting points for a precise fit and stable performance under vibration and heat. Use it as a direct replacement during routine servicing or when the original frame is cracked, warped, missing, or no longer holding the filter evenly.
