An air cleaner for a combustion engine including air and fuel induction passages is provided and the air cleaner defines an inner chamber downstream from an associated air filter element. The inner chamber opens into the air and fuel induction passages of the engine and a reservoir for an evaporative liquid is provided, including an upper portion defining a filtered air inlet and a vapor outlet. An elongated conduit extends between and communicates the vapor outlet with the inner chamber within the air cleaner and a liquid absorbent and porous body is provided within the chamber for floating on the liquid therein, the body when in use defining increased wetted surface area from which liquid contained within the reservoir may be evaporated by air entering the reservoir through the air inlet and being drawn from the reservoir through the vapor outlet.
