AIR CLEANER FILTER ELEMENT
The Viper air inlet system does not preheat ambi-
ent air. O n the Coupe model the majority of the inlet
air is directed into the air cleaner front housing from
the hood mounted N A C A duct (Fig. 44) or (Fig. 45).
On the Roadster model the airduct connects directly
to the front portion of the air cleaner. On both mod-
els the incoming ambient air passes through two f i l -
ter elements i n the air cleaner. F r o m the filters
ambient air passes through the throttle bodies into
the intake manifold.
