Intake system for an internal combustion engine

摘要

An intake system for an internal combustion engine includes an intake manifold adapted to be attached to a side wall of the engine, and an air cleaner for supplying intake air to the intake manifold. The air cleaner is disposed opposite to the side wall of the engine while interposing therebetween the intake manifold. The air cleaner has an air cleaner main body joined with the intake manifold to constitute a single unit. The air cleaner main body is made of a material lower in the strength than a material which the intake manifold is made of.
