Claim 16:
17. A method of providing filtered air to a vehicle component comprising:
assembling a secondary air induction system to an inlet air conduit downstream from an air cleaner, wherein the air inlet conduit has an upstream end, wherein the secondary air induction system includes an inlet port, 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 and is attached to an external surface of the inlet air conduit with the inlet port radially outboard and axially aligned with the upstream end;
drawing air through an air cleaner and into the inlet air conduit;
supplying a first portion of the air from the air inlet conduit to an engine;
drawing a second portion of the air into the inlet port located at an axial distance upstream from a mass air flow sensor disposed in the inlet air conduit, wherein the upstream end and inlet port are located at the same axial distance from the mass airflow sensor, wherein the air is drawn through the secondary conduit, and through an outlet port of the secondary air induction system with an air pump; and
supplying air from the secondary air induction system to the vehicle component located downstream from the engine.
