STIHL HS81R HS81RC HS81T HS81TC HS86R HS86T Paper Air Filter

Air filter fits Stihl HS81R, HS81RC, HS81T, HS81TC, HS86R and HS86T hedge trimmers. Replaces part number 4237 141 0300. The filter removes dust, plant particles and airborne debris from intake air to prevent contamination of the carburettor and engine.

Maintaining clean airflow supports stable engine performance, helps ensure efficient combustion, and reduces wear on internal engine components. A clogged or deteriorated filter restricts airflow, which can lead to loss of power, hard starting, increased fuel consumption and accelerated wear of internal parts.

This replacement air filter matches the original dimensions and fitment, providing a direct swap when the existing filter becomes soiled or damaged. Regular replacement helps maintain the design operating conditions of the engine and supports consistent performance across all listed hedge trimmer models.
