Air Box Foam Filter For GY6 Scooters
The Air Box Foam Filter from jtfrkope is designed for a broad range of GY6-based scooters, including 49cc and 50cc models and popular older variants such as 139QMB Taotao Jonway.

It is compatible with VM22, PZ22, PZ27, and PD18J carburetors, making it a practical replacement when OEM parts are scarce. The filter’s 38mm diameter matches many Taotao, Roketa, and Jonway intake boots, helping to maintain proper fuel-air mixing and engine performance across a spectrum of Chinese-made scooters. Its broad compatibility helps simplify maintenance and reduce stocking requirements for shops and riders.
The EOPOAYI filter provides a straightforward upgrade path for riders upgrading to better filtration without a custom part search. With a proven track record across multiple scooter platforms, it stands out as a versatile option for owners who value flexibility and reliability.

39mm GY6 Air Filter
Cyleto’s 39mm air filter is built for Gy6-based scooters and motorcycles from 50cc to 200cc, delivering higher airflow than standard filters. Race-tested for performance and reliability, the filter claims up to 25% more air flow over typical stock units. This improved flow can improve throttle response and overall engine efficiency, especially under load or during acceleration. The 39mm size is common among many GY6 intake configurations, making it a convenient upgrade for riders seeking a balance between filtration and horsepower gains.
When selecting this filter, verify the carburetor diameter and compatibility with your intake boot. The design emphasizes performance-oriented filtration, which can be favorable for riders who push their scooters in mixed riding conditions or who require additional airflow for tuned setups.
42-44mm Filter For GY6
QAZAKY’s 42-44mm filter covers a broad range of GY6 engines, including 33cc to 52cc minimoto and many China-made scooters.

This versatility can reduce the need for numerous different filter sizes.
With its broad compatibility and adaptable sizing, this filter supports diverse riding setups, especially for those who keep a stable of small displacement machines. It’s a practical option when stock variety is limited but performance and protection remain priorities.
Buying Guide
Fitment And Size
Air filter size must match the scooter’s intake diameter and carburetor connection. Common sizes for GY6-based scooters range from about 38mm to 44mm. Confirm the exact diameter of your carb inlet and the boot adapter before purchasing. Incompatible sizes can restrict airflow or cause intake leaks, reducing performance or engine reliability.
Filter Material And Construction
Foam and synthetic foam filters (like the Air Box Foam Filter) are typically washable and re-usable, offering long-term value when properly maintained. Paper filters, by contrast, may offer excellent initial filtration but are usually single-use. Foam tends to tolerate wet or dusty environments well, while some riders prefer the higher filtration efficiency of specialized paper elements. Consider maintenance habits and local dust levels when choosing.
Performance Versus Longevity
Higher airflow can improve throttle response and peak power, but it must not compromise filtration. Filters advertised as “race” or “high airflow” often trade some filtration efficiency for more air. For everyday riding, a balance between filtration and airflow is ideal. Review product specs and user experiences to gauge real-world gains without exposing the engine to excess debris.
Compatibility And Coverage
Many filters listed are designed to fit multiple models across 50cc to 150cc classes and various Chinese brands. When possible, select a filter with documentation or listings that explicitly mention your scooter’s model, year range, and carburetor type. A flexible, 2-pack option can reduce downtime and ensure you have a ready replacement if a filter wears out.
Maintenance, Reuse, And Cleaning
Filters that are washable and re-oiled tend to offer better long-term value. Proper cleaning and oiling extend the filter’s life and sustain filtration performance. Follow manufacturer guidance for cleaning intervals, and use compatible filter oils to preserve mesh or foam integrity. Regular inspection for tears or deformation helps prevent intake leaks.
Value, Availability, And Supporting Parts
Consider whether the seller offers multi-pack options, which can lower per-unit costs and simplify stocking for shops or clubs with several riders. Availability matters, especially for older or less common scooter models where OEM parts are scarce. A versatile filter with broad compatibility can reduce the need for multiple part numbers.
