4228 141 0500 STIHL Filter Cover – Genuine OEM Part
The STIHL Filter Cover (4228 141 0500) is a genuine OEM replacement cover designed for use on select STIHL HS 45 hedge trimmers. This component protects the air filter assembly and helps ensure proper sealing around the air filter and spacer flange, preventing dirt and debris from entering the engine intake system.
A properly functioning filter cover is essential for maintaining clean airflow, protecting the carburetor, and ensuring reliable engine performance. A cracked, loose, or missing filter cover can lead to poor filtration, reduced power, increased engine wear, and premature fuel system issues.
