Physical instruments are listed here in alphabetical
order. Some are optional and therefore not found in
every vehicle. Digital instruments and gauges are
described in their ICU section.
Air Intake Restriction Gauge
The air intake restriction gauge indicates the vacuum
on the engine side of the air cleaner. On standard
installations, it is mounted on the air intake duct in
the engine compartment, and has a go/no-go
restriction indicator without graduations. See
Fig. 3.32. As an option, a graduated indicator, shown
in Fig. 3.33, on the air intake duct or, for easier
viewing, a dash-mounted restriction gauge may be
installed.
