Claim 0:
1. An air induction system for an engine comprising: an air cleaner enclosing a filter element that removes contaminants from air supplied to the engine; an inlet air conduit defines an upstream end of the inlet air conduit disposed downstream from the air cleaner, wherein the inlet air conduit supplies air to the engine; a mass air flow sensor (MAFS) disposed in the inlet air conduit measures the mass of air flowing through the inlet air conduit to an intake manifold of the engine and provides mass air flow data to an engine control module; and a secondary air system receives air from the air cleaner that is provided to a vehicle component, the secondary air system includes an inlet port located upstream from the MAFS, a secondary conduit attached to an outer surface of the inlet air conduit, wherein the secondary conduit is isolated from the inlet air conduit, wherein the inlet port of the secondary conduit is disposed radially outboard of the upstream end of the inlet air conduit, and an air pump that draws air into the inlet port, wherein the inlet port of the secondary conduit is disposed radially outboard of the upstream end of the inlet air conduit and wherein the upstream end and the inlet port are at substantially the same distance from the air cleaner.
