Intake module of M57
The intake module consists of three main components, i.e. the cylinder head cover, intake manifold as well as the intake silencer together with the air cleaner.
The cylinder head cover and the intake manifold are made from glassfibre-reinforced polyamide (plastic) and mounted acoustically isolated by means of rubber elements on the cylinder head.
The intake module fulfills the following tasks:
• Cover for camshaft chamber
• Damping of intake noise
• Filtering of intake air
• Engine ventilation and oil separating
• Air guide/distribution to the inlet ports (tangential and swirl ports)
M67 E38
• Two vehicle-specific intake air silencers
• Air cleaner change interval: approx. 100,000 km (under normal conditions)
• Intake points same as on the M73
• Hot-film air mass meter (HFM), flange-mounted
