STIHL BG45 BG46 BG50 BG55 BG65 BG85 SH55 SH85 Air Filter

The Gasket Genius air filter fits Stihl BG45, BG46, BG50, BG55, BG65, BG85, SH55 and SH85 leaf blowers. Replaces part number 4229 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.

These filters are typically foam-type elements, allowing effective filtration while maintaining proper airflow for small petrol engines.

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, helping restore proper air intake filtration and reliable engine operation across all listed models.
