Description
Overview:
This is a Genuine Stihl air filter, part number 4149 120 1800, for keeping small two‐stroke engines breathing clean air. It is designed for Stihl hedge trimmers and brushcutters, including the HL94 and FS94 ranges. The filter element uses quality non‐woven media to trap fine dust, grass particles, and debris while maintaining the correct airflow to the carburettor.
