Description

The UNIFILTER NU-4105ST is a dual-stage foam air filter designed for specific Honda dirt bike models. It features two layers of foam: a large pore pre-filter to capture larger particles and a small pore inner filter to prevent fine grit from reaching the engine. This competition air filter is reusable after cleaning and oiling. It is used by offroad teams from Kawasaki, Yamaha, and Suzuki.
