Product Overview
This 58mm air filter is designed for a wide range of small engine motorcycles, ATVs, scooters, go-karts, mopeds, pit bikes, dirt bikes, racing bikes, pocket bikes, and motorized bicycles.
With a 58mm / 2.28" inner diameter, this replacement air filter is suitable for many 50cc–250cc 2-stroke and 4-stroke engines, including compatible GY6 engines and selected mini bike or pocket bike applications.

Fitment FAQ
Will this part fit my specific model and year?
This 58mm air filter may fit many 50cc, 70cc, 80cc, 90cc, 110cc, 125cc, 140cc, 150cc, 200cc, and 250cc 2-stroke or 4-stroke engine applications, including compatible GY6 engines, ATVs, quads, scooters, go-karts, mopeds, pit bikes, dirt bikes, racing bikes, pocket bikes, and motorized bicycles. However, air filter fitment is mainly determined by the carburetor intake diameter, not only by the vehicle model, year, or engine displacement. Please measure your carburetor inlet and make sure it matches the 58mm / 2.28" inner diameter of this air filter before ordering.
Do I need to match the OEM part number?
For this type of universal-style replacement air filter, matching the OEM part number is helpful but usually not required. The most important fitment detail is whether your carburetor intake size matches 58mm and whether the filter shape, clamp style, and installation space are similar to your original part. If your original air filter mounts to a 58mm carburetor inlet, this part may be a suitable replacement. We still recommend comparing your old filter, carburetor inlet size, and product photos before purchase.
What models or situations does this part not fit?
This air filter will not fit carburetors with an intake diameter smaller or larger than 58mm. It may also not fit vehicles that require a factory air box, a special angled filter, a different mounting style, or limited clearance around the carburetor. It is not recommended for carburetors that require 35mm, 38mm, 42mm, 44mm, or other air filter sizes. Please do not order based only on “50cc–250cc” or “GY6,” because different engines, carburetors, and vehicle setups may use different air filter diameters.
What should I check before ordering?
Before ordering, please confirm that your carburetor intake diameter matches the 58mm / 2.28" inner diameter of this air filter. Also compare the filter shape, clamp position, mounting style, and available space around the carburetor with your original air filter. This part is commonly used on compatible 50cc–250cc 2-stroke and 4-stroke engines, GY6 engines, ATVs, scooters, go-karts, mopeds, pit bikes, dirt bikes, and pocket bikes, but correct fitment depends on the actual carburetor inlet size and installation layout. If you are unsure, measuring your old air filter or carburetor inlet before purchase is the best way to avoid ordering the wrong part.
