OEM STIHL Spark Arrestor Screen – 1141 140 8100 (MS261 / MS271 / MS291)

Keep your chainsaw running safely and efficiently with this genuine OEM STIHL spark arrestor screen (Part #1141 140 8100). Installed in the muffler, this screen helps prevent sparks from exiting the exhaust, reducing the risk of fire—especially in dry or wooded conditions.

Over time, spark arrestor screens can become clogged with carbon buildup or deteriorate from heat, leading to reduced engine performance. Replacing the screen restores proper airflow and helps maintain peak chainsaw operation.
