Description
Overview:
This air filter is the intake filtration element for Stihl MS 151 C-E and MS 150 C-E chainsaws. It sits in the air box to remove fine dust and wood chips from the incoming air before it reaches the carburettor and cylinder, helping protect the piston and bore from abrasive wear. The filter’s moulded frame and fine media provide reliable sealing and consistent airflow for stable starting and running under normal site and arborist conditions. This is a Genuine OEM replacement part from Stihl, supplied to the same specification as the factory‑fitted filter. Direct replacement for OEM No. 1146 140 4403. Designed for quick swap during routine servicing to keep performance and fuel usage consistent in light felling, pruning, and general cutting work on compact saw platforms such as the MS 151 C-E and MS 150 C-E.
