Description
Overview:
This Prefilter (1127 124 1501) is a genuine Stihl air-intake prefilter for petrol chainsaws in the 1127 series, including MS 290 and MS 310. Made from durable non-woven felt media, it sits ahead of the main air filter to capture coarse dust and chips before they reach the primary element. By reducing contamination, it helps maintain clean airflow to the carburettor and cylinder, protecting critical engine parts and supporting consistent performance between services. The pad is sized to suit the standard filter housing on these models and is straightforward to replace during routine maintenance. Using the correct OEM prefilter preserves filtration efficiency, extends the life of the main filter, and helps minimise premature wear when cutting in dusty environments. Genuine Stihl part for assured fit and reliability.
Key Features:
- Genuine Stihl OEM prefilter for accurate fit and correct airflow
