MS381 Chainsaw Air Filter – Heavy-Duty Replacement & Service Kits
Essential Air Filtration for STIHL MS381 & MS382 Chainsaws
The air filter is a key component of the MS381's air intake system, responsible for preventing dust, sawdust, and debris from entering the engine. A clogged or damaged filter restricts airflow, leading to reduced performance, hard starting, and increased fuel consumption. This replacement filter is designed for STIHL MS381, MS382, and their predecessor 038 models, available as individual felt/fleece elements or as part of comprehensive service kits.
Technical Profiles & Materials
Heavy-Duty Filtration – Felt/fleece construction effectively traps coarse dirt particles on the surface while capturing fine dust inside the filter media. This protects the engine from abrasive particles, maintaining power and keeping fuel consumption low .
OEM-Spec Compatibility – Available as a direct replacement for OEM part numbers 1119 120 1607, 1119 120 1628, and 1141 120 1600. Ensure your MS381 variant matches the correct specification before ordering .
Service Kit Options – Complete service kits (e.g., STIHL Service Kit 1) include the air filter, spark plug, and fuel filter in one package, enabling straightforward standard maintenance .
Easy Installation – Designed for tool-free replacement with the combination socket tool provided with your STIHL chainsaw .
