The Stihl Prefilter 4228 124 1500 is a genuine OEM foam air prefilter designed for Stihl petrol hedge trimmers. Positioned in the air intake system, it traps dust, grass particles, and fine debris before they reach the carburettor and engine. This helps maintain steady airflow, ensuring easier starting, smoother running, and consistent cutting performance.
Made from durable foam, the element resists tearing and distortion when fitted correctly and serviced on schedule. It provides a precise fit for Stihl HS 45 and HS 52 hedge trimmers, making routine maintenance quick and effective for both professional landscapers and home users.
By replacing a clogged prefilter, you can restore airflow, improve fuel efficiency, and protect the engine and main filter from premature wear. Available now from Cambrian Plant Sales, this genuine Stihl part is an affordable way to extend service life and keep hedge trimmers running at their best.
