3X STIHL BG56 BG56C BG66 BG66C BG85 BG86 SH56 Air Filter

The Gasket Genius air filter set (3 pcs) fits Stihl BG56, BG56C, BG66, BG66C, BG85, BG86 and SH56 leaf blowers. Replaces part number 4241 120 1800. Each filter is designed to trap dust, dirt and airborne particles from intake air before it enters 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, leading to reduced power output or increased fuel consumption.

This 3‑piece filter set provides multiple replacement elements for scheduled maintenance. Suitable as direct replacements when original filters are worn, soiled or damaged, helping maintain proper air intake filtration and reliable engine function across all listed blower models.
