Drill four 3 ⁄
16
" diameter holes through the air inlet hood
bracket around the perimeter of the center hole. See
Figure 5 . If the bracket cannot be drilled while in place, it may
be unbolted for drilling.
Slip the bulkhead fitting 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 points.
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 fitting.
Determine a location for the Ram-Air Super-Scoop. 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 Super-Scoop 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 6. Use heavy
snips or a hack saw to trim the air inlet opening of the Scoop.
The height between the Super-Scoop and the air inlet hood should be
as great as possible to prevent any rain water not eliminated by the
Scoop’s water drain hole from climbing up into the air filter. The curved
outlet section of the Super-Scoop may be trimmed back if less bend is
required to make a more streamlined hose routing. See Figure 7.
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 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 Super-Scoop somewhere else, such as in 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 spray.
Once a location has been determined for the Super-
Scoop, mount it using one of the following methods.
If the grille consists of horizontal bars or a perforated metal
screen heavy enough to support the Scoop, it may be secured
using four 1 ⁄
4
" clear nylon cable ties, provided, slipped through
the ears on the Scoop and through the grille. See Figure 8 .
An alternate method is to mount it 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 conve-
nient 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 be used.
Connect the bulkhead fitting to the Super-Scoop using
the 4" diameter flex hose provided. Cut the hose to the
desired length using a knife and diagonal cutting pliers. Secure
with two No. 64 hose clamps. 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 Super-Scoop with the 4" diameter flex duct provided. Use
the plastic bulkhead fitting as a coupling between the hoses, and
trim off the curved section if desired. Attach the flex hoses with
four No. 64 hose clamps. You may want to tie the plastic
bulkhead fitting down to keep it in place. See Figure 6 .
