STIHL HS46 HS46C HS56 HS56C Hedge Trimmer Air Filter

The Gasket Genius air filter fits Stihl HS46, HS46C, HS56 and HS56C hedge trimmers. Replaces part number 4242 120 1800. The filter is designed to trap dust, dirt and airborne particles from intake air before it reaches the carburettor and engine, ensuring clean airflow during operation.

Maintaining clean intake air supports stable engine performance and helps reduce wear on internal engine components. A clogged or contaminated filter can restrict airflow and lead to reduced power output or increased fuel consumption.

Suitable as a replacement air filter where the original element is worn, soiled or damaged, restoring proper air intake filtration and reliable engine function across all listed hedge trimmer models.
