High performance air filters can provide increased horsepower by allowing better air flow than a stock air filter. Our air filters fit a variety of Pocket Bikes, Scooters, Atv’s, Dirt Bikes, Buggies, Go-Karts and many other small gasoline engines. Choose from a variety of mounting sizes ranging from 32mm, 35mm, 38mm, 39mm, 42mm, 44mm, 48mm and 58mm.

A Velocity Stack/Air filter adapter is required for some models when upgrading to a high performance air filter.
