About This Item
Replacement air filter cartridge 4-pack designed to keep small engines breathing clean air during routine service and seasonal tune-ups. Replaces 4134 141 0300 / 4134-141-0300; compatible with Stihl FR350 / FR450 / FR480 / FR480C, FS120 / FS200 / FS250 / FS300 / FS310 / FS350 / FS380 / FS400 / FS450 / FS480, HT250, KM130 / KM130R, BT120 / BT120C / BT121 / BT121Z / BT130, MM55, SP90 / SP90T / SP200 / SP400 / SP401 / SP450 / SP451 / SP471 / SP481. The filter helps reduce dirt, dust, and debris entering the carburetor and engine, supporting airflow and smoother operation; a clogged filter can contribute to power loss, so check the filter when performance drops and replace as needed (recommended each season for consistent results). Dimensions: 3-1/2 in x 2-3/4 in x 1 in; verify your existing filter matches the shape and measurements before ordering to ensure proper fit and sealing.
