Air Induction System
Ambient air is drawn into the air cleaner assembly and
passes through a paper element filter. A filter minder
monitors air filter restriction and is calibrated to warn
when it needs servicing. As filtered air approaches
the turbocharger, it passes over the pitot tube creating
a vacuum and draws engine blow-by gases through
a breather element located under the left side valve
