Multi-shell air intake manifold with passage for map sensor and method of producing same

Abstract

An air intake manifold assembly for an internal combustion engine composed of a plurality of molded synthetic resin shells assembled to each other so as to define a plenum chamber, a plurality of inlet channels leading from said plenum chamber to cylinder inlets of the internal combustion engine, and a throttle body passageway leading from a throttle body mount into the plenum chamber; with a groove formed in a surface of at least one of the shells facing an adjacent shell and extending from an inlet opening to the throttle body passageway or the plenum chamber so as to form an elongate passage between the assembled shells leading from the inlet to the throttle body passage or plenum chamber, and a method of forming such an intake manifold assembly.
