Abstract
An air induction assembly 10 disposed in an intake passage through which air flows to an engine. The air induction assembly 10 has a conduit member 20 which defines an air flow path. A mass air flow sensor (MAFS) 30 is located in the intermediate conduit portion and is in fluid communication with the air flow path. The MAFS 30 being operative to generate an output signal corresponding to air flow rate within the intermediate conduit portion A plurality of flow conditioning elements (FCEs) 22 in the airflow path produce a uniform airflow with low turbulent fluctuations to the MAFS 30 under all vehicle and engine speeds without excessively restricting the air flowing to the engine.
