STIHL BG56 BG56C BG66 BG66C BG85 BG86 SH56 Air Filter

The Gasket Genius air filter fits Stihl BG56, BG56C, BG66, BG66C, BG85, BG86 and SH56 leaf blowers. Replaces part number 4241 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 restricts airflow and may lead to reduced power output or increased fuel consumption.

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