RFI COLD AIR INTAKE
RFI COLD AIR INTAKE
Parts Description
RFI Enclosure Lid
The easy-to-remove lid
allows for hassle-free filter
maintenance. Heavy duty
latches ensure that the lid
creates a good seal with the
enclosure base and that the
latches close securely.
RFI Enclosure Base
There are four enclosure
features to note to ensure a
smooth installation: (1) the
foam secured to the inlet of
the box which allows it to
seal tightly to the side of the
truck, (2) the round hole on
the bottom of the box which
allows for drainage and even more cool airflow from the wheel
well, (3) the mounting pegs that are located on the bottom of the
enclosure and used to secure the enclosure base to the OEM
mounting plate in the engine bay, and (4) the circular hole on the
back of the enclosure where the intake tube will be attached.
Air Intake Tube with MAF Mount
The air intake tube comes
with a precision-made
mass air flow sensor mount
with inset screw mounts.
The tube is designed with
a snap-fit feature that will
secure it to the RFI base.
