Abstract
A low cost combined air cleaner and resonator includes two housing members which snap together. An air filter is captured between the two members. A first of the members receives the air filter, and the second of the two members has an enlarged plenum to provide a resonator function. The combined air cleaner and resonator thus provides a low cost way of achieving both functions in a system for supplying clean air to a vehicle engine.
