Claim 11:
12. An apparatus comprising:
an engine having an air induction system that supplies air to the engine at a controlled rate by an engine control module that controls the air/fuel mixture provided to the engine, the air induction system having a Mass Air Flow Sensor (MAFS) disposed inside an inlet air conduit of the air induction system, wherein the inlet air conduit includes an upstream end; and
a secondary air flow system provides air to a vehicle component, the secondary air flow system includes an inlet port located upstream from the MAFS, wherein the inlet port of the secondary air flow system is disposed radially outboard of the upstream end, and wherein the inlet port and the upstream end are at substantially the same distance from the air cleaner, and a flow straightener disposed inside the inlet air conduit that defines a flow straightener inlet port located at the upstream end of the inlet air conduit, and wherein the inlet port of the secondary conduit is disposed radially outboard of the flow straightener inlet port of the flow straightener, wherein the inlet port supplies air to a secondary conduit isolated from the inlet air conduit, and an air pump that draws air into the inlet port, wherein the secondary conduit is disposed radially outboard of the inlet air conduit.
