Banks Power GM Motorhomes: (Gas ’82 - 95 7.4L) PowerPack system (EFI TBI, P30 chassis) - Manual (Page 6)

INSTALLATION PROCEDURE
The Banks Ram-Air cold air induction components are designed
to extend the factory air intake path so that cooler outside air
can be picked up from directly behind the vehicle’s grille. Figure
2 shows a typical hook-up of the air intake components as they
tie to the factory system. The Ram-Air Super-Scoop ™ also serves
as a water separator to drain out any rain water that may enter
through the grille.
The Banks Ram-Air System is intended to fit a number of
motorhome body configurations. Because each coachbuilder
has a different layout of behind-the-grille components, there can
be no one set installation procedure for the Banks Ram-Air
System. The following instructions are intended as a guideline for
installing the system. Also, some coachbuilders may have
installed difficult to relocate components (such as air condition-
ing freon piping) in the areas where the Banks Ram-Air system is
normally mounted. In these cases, the installer will have to find
an alternate location for the Ram-Air components, or omit or
modify those pieces that are difficult to accommodate.
Install the foam gasket strip in the groove around the
outside edge of the air filter cover casting. Peel the
paper off the gasket to expose the adhesive. Trim the ends
square with a knife or razor blade to form a tight junction. Do
not stretch the gasket as you install it.
Remove the engine hatch cover from the vehicle. Remove
the air filter cover and filter element. Clean any oil or debris
from the inside of the air filter base. On some models, the air filter
base will have a sheet metal dust shield welded to the inside
diameter of the base. Cut and remove the shield to allow for
maximum air flow. Install the new air filter element and air filter
cover casting. If your original air filter cover has tune up and
emissions specifications on it, save it for future reference.
Determine a path for the inlet air ducting from the air
filter base forward to the vehicle’s grille. Some vehicles
have a plastic air inlet duct attached to the snorkel on the base
of the air filter. This duct typically draws air through a plastic air
inlet hood that is mounted either above, or to one side of the
radiator. If this duct and hood are in place, proceed to step 4. If
not, skip steps 4 thru 8 and proceed to step 9.
Disconnect the plastic factory air inlet duct at the air inlet
hood. Remove the air inlet hood from the mounting
bracket by twisting it until the four tabs line up with the slots in
the bracket. See Figure 3 .
Insert the Banks plastic bulkhead fitting through the
bracket from the back side. The bulkhead fitting may be
used as is, or the curved portion may be cut off if this lines up
better with the factory air inlet duct. Figure 4 shows where to cut
the bulkhead if the curved portion is to be removed.
