Description
Overview:
This Genuine Stihl fan housing (OEM No. 4180 080 1800, MPN 41800801800) is a tough, high-impact polymer cover designed to manage cooling airflow and protect the engine on Stihl brushcutters. It sits over the flywheel area to channel air across the cylinder and ignition components, helping to keep temperatures stable under load and guard against debris ingress. Built for an exact OE fit and finish in the familiar Stihl orange, it uses the original mounting points for a straightforward swap with standard hand tools. Ideal for maintaining reliable performance on machines such as the FS100 and FS110, it withstands regular site or garden use, vibration, and exposure to fuel and oil, helping extend engine life and reduce the risk of overheating-related issues.
