Description
4229 141 0502 STIHL Filter Cover – Genuine OEM Air Filter Part
The STIHL Filter Cover (4229 141 0502) is a genuine OEM air intake component designed to protect and secure the air filter assembly on STIHL handheld blower equipment. This cover ensures the air filter remains properly enclosed, allowing clean airflow into the carburetor for consistent engine performance and long-term reliability.
Over time, filter covers may crack, warp, or loosen due to vibration, heat exposure, debris impact, or repeated maintenance. A damaged or missing cover can allow dirt and debris into the air intake system, leading to poor carburetor performance, reduced engine efficiency, and premature engine wear. Replacing it with the correct OEM part helps restore proper filtration protection without replacing the entire air filter housing assembly.
Manufactured to STIHL factory specifications, this genuine filter cover ensures correct fitment, sealing, and durability under professional operating conditions.
