3X STIHL FS94 FS94C FS94RC HL91KC HL92C HL92KC HL94C Air Filter

The Gasket Genius air filter set (3 pcs) fits Stihl FS94, FS94C, FS94RC, HL91KC, HL92C, HL92KC and HL94C strimmers / brushcutters. Replaces part number 4149 120 1800. Each filter is engineered 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 restricts airflow and can lead to reduced power output or increased fuel consumption.

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