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.

Low cost combined air cleaner and resonator assembly

A cuff is clamped to a boss on an air resonator. The cuff has an inner leg with an o-ring seal sized to provide a seal against an inner periphery of the air resonator boss. A throttle body has a boss to be received within the inner leg of the cuff, and will also deform the o-ring seal. The inner leg preferably includes a second forward seal which also contacts the throttle body boss. Preferably, this second seal includes a spring for biasing the second seal against the throttle body boss. The cuff is initially placed on the air resonator which may then be mounted within the engine compartment. The throttle body may be then simply snapped into the cuff. In this way, no space around the connection is necessary, while a dust-free connection is still provided.
