Description
Overview:
This genuine Stihl air filter is a direct-fit replacement for the MS 201 and MS 201 T petrol chainsaws. It sits in the intake system to clean the air before it reaches the cylinder, helping the engine breathe freely and run reliably. The element uses a fine-mesh synthetic media held in a rigid plastic frame to trap dust, chips, and abrasive particles while maintaining airflow. Using the correct OEM filter protects the piston and bore, supports consistent power, and reduces premature wear in demanding cutting environments. Supplied as OEM No. 1145 140 4406, it is built to Stihl specifications for fit and performance. A Genuine Stihl part, it suits routine maintenance for both professional users and DIY owners who expect dependable service from their saw.
