The Twin Air motorcycle air filter features a dual-layer construction made from two layers of foam. The open-cell foam on the outside traps dirt, soot and sand, while the finer foam on the inside captures smaller particles and allows air to pass through.
The two layers are securely bonded to prevent particles from becoming trapped between them. The wide support foam fits against the filter housing and acts as an air-permeable seal.
