Abstract
A method and device are disclosed for tuning an air induction system of an internal combustion engine in which an expansion chamber is combined with a Helmholtz resonator tuned to resonate at the engine speed whereat the expansion chamber would otherwise cause an engine torque decline, the combined effects tuning the system over the entire operational range of speeds of the engine.
