4147 129 0902 – STIHL Air Filter Spacer Flange Gasket (Genuine STIHL OEM Part)
The STIHL 4147 129 0902 Gasket is a genuine OEM sealing gasket designed for the air filter spacer flange on selected STIHL professional brushcutters. Engineered to STIHL's exact factory specifications, this gasket creates an airtight seal between the spacer flange and air filter assembly, preventing unfiltered air from entering the engine while ensuring maximum filtration efficiency and consistent engine performance.
