Product Description
Restore proper engine performance and protect your engine with this complete OEM-style air filter housing assemblyfor most Chinese 50cc scooters equipped with a 139QMB (QMB139) 4-stroke engine. This complete airbox includes the air filter element already installed, making it an excellent replacement for cracked, damaged, or missing factory air boxes.
The factory airbox is engineered to provide the correct airflow while filtering out dirt, dust, and debris that can prematurely wear your engine. Replacing a damaged air filter housing helps maintain proper air/fuel mixture, smoother throttle response, reliable starting, and longer engine life. OEM-style replacement assemblies are designed to match the original fitment and airflow characteristics of the stock intake system.
