Description
A replacement 37 mm – 39 mm straight foam air filter for 125cc-150cc ATVs, dirt bikes, go-karts, and pit bikes can make a world of difference in your engine’s performance. All too often a dust-saturated filter just won’t allow the full amount of clean air into the carburetor, and an air-starved carb isn’t going to give anything but very marginal performance. The solution is one of these great little 4-stroke performance foam air filters with a 37 mm to 39 mm mounting diameter.
Each air filter comes with a sleeve in your choice of color options that can be removed for cleaning. In addition, there is a hose clamp to get the filter down snug on your carburetor’s external air intake. The size is most commonly found on the external air intakes on the carburetors made for Chinese-made GY6 engines. If your ATV, dirt bike, go-kart, dune buggy, or pit bike uses a 125cc or 150cc GY6 engine, then measure your carburetor’s air intake. There is a very good chance that it will be in the 38 mm – 39 mm range; and if so, then these are the filters that you want.
Now you can upgrade your air filter for increased intake and far better performance.
