SYSTEM-AIR INTAKE
DESCRIPTION
Air deflectors mounted to the hood and front grill route
the cool incoming air intothe right inner fender (3)
where the inlet for the air cleaner housing (4) resides.
Air passes through a filter element inside the housing,
through a air inlet duct (1), and into the throttle body.
