Banks Power GM Motorhomes: (Gas ’82 - 95 7.4L) PowerPack system (Carbureted, single air pump) - Manual (Page 5)

inStallation Procedure
the banks PowerPack 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. These compo-
nents include a molded banks Super-Scoop™, banks
ram-air™ filter cover, 4” diameter flexible turbine,
a molded bulkhead fitting, and installation hardware.
Figure 2 shows a typical hook-up of the air intake
components as they tie to the factory system. the
banks Super-Scoop also serves as a water separator
to drain out any rain water that may enter through
the grille.
the banks PowerPack cold air induction package is
intended to fit a number of motorhome body config-
urations. 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 package. the following instructions are intended
as a guideline for installing the ram-air system. also,
some coachbuilders may have installed difficult to
relocate components (such as air conditioning freon
piping) in the areas where the ram-air system is nor-
mally mounted. in these cases, the installer will have
to find an alternate location for the ram-air compo-
nents, or omit those pieces that are impossible to
mount.
install the foam gasket strip in the groove
around the outside edge of the ram-air
filter cover casting. Peal 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. install the new banks ram-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 duct-
ing 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 pro-
ceed 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 .
