Universal Parts Air Filter - 139QMB 50cc Long Case Scooters
Description
This Universal Parts Air Filter (SKU 151-294) is a cartridge-style replacement filter for long case 139QMB (QMB139) 50cc 4-stroke scooters, the Chinese GY6 50cc platform based on Honda's GY6 design. Long case engines are typically found on scooters with 12" wheels and a 729-length drive belt. A clogged filter robs power and hurts fuel economy, so swap it at every major service.
Key Features
- Dual-stage element: Foam pre-filter on one side, red pleated paper on the other.
- Cartridge style: Black plastic frame drops straight into the airbox.
- Direct replacement: Matches the stock long case filter shape.
