* Drill four 3 ⁄
16
” diameter holes through the
air inlet hood bracket around the perimeter
of the center hole. See Figure 7. If the bracket
cannot be drilled while in place, it may be
unbolted for driling.
Slip the bulkhead fitting (Figure 1, #D )
into the end of the factory air intake duct,
and rotate the bulkhead fitting into the desired
mounting position. Have someone hold the
bulkhead fitting against the mounting bracket
from the back side while you mark the centers
of the four drilled hole locations. drill four 1 ⁄
16
”
diameter holes into the bulkhead fitting at these
pints.
Now bolt the bulkhead fitting to the
bracket using four no. 6 x 1 ⁄
2
” sheet metal
screws. Hook up the factory flex hose from the
air filter base to the bulkhead fiting.
Determine a location for the Ram-Air
inductor (Figure 1, #A ). It should be placed
as low as possible directly behind the grille, with
the air inlet opening pointing straight ahead. If
the grille is at an angle, the ram-air inductor
should be trimmed at an angle to place the air
inlet opening against the back side of the grille
with the centerline of the inlet opening horizontal.
See Figure 3 . use heavy snips or a hack saw to
trim the air inlet opening of the plastic inductor.
The height between the Ram-Air inductor and the
air inlet hood should be as great as possible to
prevent any rain water not eliminated by the air
inductor’s water drain hole from climbing up into
the air filter. The curved outlet section of the ram-
Air inductor may be trimmed back if less bend
is required to make a more streamlined house
routing. See Figure 3 .
for motorhomes that do not have the plastic air
inlet hood or any air inlet ducting connected to the
snorkel on the air filter base, we have provided an
additional 3-foot length of a 4” diameter flex hose
(Figure 1, #C ) to run from the air filter base past
the radiator. There must be at least a 2 1 ⁄
4
” high
clearance between the floor of the coach and
the top of the radiator bulkhead panel for the flex
hose to pass through. If this clearance does not
exist, it may be possible to mount the ram-air
inductor somewhere else, such as i n a wheelwell,
etc. It should be located where it will receive the
coolest air available, and be shielded from foreign
materials such as flying stones and excess water
pray.
Once a location has been determined for
the Ram-Air inductor (Figure 1, #A ), mount
it using one of the methods outlined below.
The ram-air inductor may be mounted by several
means. If the grille consists of horizontal bars of a
perforated metal screen heavy enough to support
the inductor, it may be secured using four 14”
black nylon cable ties, provided, slipped through
the ears on the inductor and through the grille.
See Figure 4 .
An alternate method is to mount the inductor
using the four perforated metal straps provided.
These can be bent as required and attached
to the inductor ears with the 1 ⁄
4
–20 x 1 1 ⁄
4
” hex
bolts, 1 ⁄
4
–20 nylock nuts and 3 ⁄
4
O.d. x 5 ⁄
16
I.d. flat
washers, provided. The opposite end of the straps
may be attached to any convenient mounting
points such as the gravel pan, grille brackets, etc.
as required, with four no. 10 x 3 ⁄
4
” sheet metal
screws, provided. a combination of cable ties and
straps may also beused.
Connect the bulkhead fitting to the Ram-Air
inductor using the 4” diameter flex hose
provided (Figure 1, # C ). cut the hose to the
desired length using a knife and diagonal cutting
pliers. secure with two no. 64 hose clamps
(Figure 1, #B ). If your coach does not have the
factory air inlet hood bracket, but you do have
clearance to run the 4” flex hose forward of the
radiator, join the air filter snorkel to the ram-air
inductor with the two pieces of 4” diameter flex
duct provided. use the plastic bulkhead fitting
(Figure 1, #D ) as a coupling between the hoses,
and trim off the curved section if desired. attach
the flex hoses with four no. 64 hose clamps
(Figure 1, #B ). You may want to tie the plastic
bulkhead fitting down to keep it in place. See
Figure 9 .
