12.B ESCALADE/DENALI/SS INLET DUCT INSTALLATION ('03-'06 Models)
A. Install the supplied 3-1/2" x 3" sleeve onto the
MAF outlet, and the 3-1/2" x 2" sleeve on the
inlet of the supercharger.
B. Reinstall the upper fan shroud with the excep-
tion of the top two bolts. (Excludes '06 model
year.)
C. Remove any plastic clips that are no longer
used to secure the radiator hose.
D. Slide the entry of the large plastic inlet duct
(See Fig. 12.B-d) into the sleeve installed on
the MAF. Lower the inlet duct onto the top of
the radiator shroud. Reinstall the factory radi-
ator shroud bolts through the two supplied
inlet duct mounting tabs and into their origi-
nal bolt holes.
E. Insert the supplied 1/4-20 x 1/2" screws
through the bracket and into each side of the
inlet duct using the supplied washers. Tighten
the screws. (See Fig 12.B-d.)
'06 Model Year: It will be necessary to trim
the fan shroud for the electric fans to gain
access to the screw locations. Use the sup-
plied 6mm hardware in place of missing facto-
ry hardware.
F. Using Fig. 12.B-b, drill a 9/16" hole in the
shown location. Use a 3/8"NPT tap and install
the supplied 3/8" NPT x 3/8" hose barb.
G. Install the supplied 180° inlet duct onto the
inlet of the supercharger after the supercharg-
er is installed. Orient the duct so that it
swoops over the side of the supercharger
with the end pointing at the crossover duct.
H. Install the supplied #52 hose clamps and
3-1/2" x 7" long flex hose between the two
ducts just installed.
I. Use the supplied 3/8" hose from the 3/8" fit-
ting on the inlet duct to the passenger side
valve cover breather hose. Secure the hose
so that it cannot interfere with the throttle arm
or cable. (See Fig 12.B-c.)
J. Install and tighten the hose clamps on each
connection. (See Fig. 12.B-d.)
