This air cleaner is made from 6061 aluminum and features a high flow foam filter element. The cover can be attached to or removed from the backing plate using a ¼ turn lock mechanism and is held in place by the pressure of the specially designed stainless steel spring. In addition to the cool look, the spring also acts as a cage for the filter element.

In case the air filter is to be fitted to a different carburetor or bike, the version for CV carburetors is drilled with the S&S hole pattern on the inside of the backing plate and vice versa.
