Parts Description:
This section describes each part and any special features of each part that need to be noted
to assist with installation. All parts will be referred to during installation by the names used
in this section.
The RFI base: The base of the RFI enclosure that holds the lter has a couple of features to
note. The rst is the circular hole on the back of the base, this hole is where the RFI tube will
snap into the base and hold secure the air lter. The second important part of the base is the
foam secured to the inlet of the box, which is to seal tightly to the side of the truck.
The RFI Lid: The lid is very easy to remove for lter maintenance, notice the tongue and
grove formed between the housing base and the lid needs to be properly lined up for a good
seal.The latch mounts on the lid should always match up with the latch mounts on the base.

Lid Latches: The lid latches come pre-assembled onto the RFI base and are used to secure
the lid to the base. This latch system is typical of many OEM style systems and allows for
quick and easy access to the air lter for maintenance and to clean out any debris which
may have collected inside of the lter housing.
Air Intake Tube with MAF mount: The injection molded tube comes with a precisely
manufactured Mass Air Flow sensor mount with inset screw mounts. The tube also has a
unique interference snap t feature that will tightly secure the intake tube to the RFI base.
Notice in the diagram below which end of this tube goes into the RFI base.
