This Filter Cover is a genuine Stihl OEM replacement for the HS 45 hedgecutter (also written as HS45). It encloses and protects the air filter element, helping to keep out dust, chips, and moisture during trimming work. Made from durable moulded plastic designed for outdoor use, it resists knocks and everyday wear. By sealing the filter housing correctly, it supports consistent airflow, easier starting, and reliable running.
