STIHL FR108 FS88 FS108 Felt Air Filter

The Gasket Genius air filter fits Stihl FR108, FS88 and FS108 strimmers and brushcutters. Replaces part number 4135 124 2800. The filter is designed to trap dust, dirt and airborne particles from intake air before they reach the carburettor and engine, helping maintain clean airflow and consistent engine performance.

By ensuring proper filtration, it helps reduce engine wear and performance issues caused by contaminated or restricted airflow, especially during regular use in demanding conditions.
