A. Install the supplied grommet and 3/8" elbow
in inlet duct hole (if not already completed).
B. If the vehicle is equipped with a separate air
temperature sensor, drill an 11/16" hole in the
plastic inlet duct and install the air tempera-
ture sensor and grommet in the hole. (See
Fig. 16-a.)
C. If the vehicle has a plastic line running from
the fuel regulator (located on top of the
engine, connected to the fuel rail), remove
the plastic fitting and rubber hose from the
end of the plastic line that was previously
connected to the factory air duct to throttle
body sleeve. Drill a 5/16" hole in the supplied
plastic duct, insert a short length of 3/16"
hose, insert the plastic fitting into the hose
and run the supplied 3/16" hose from the fit-
ting to the plastic fuel regulator line after the
inlet duct is installed.
D. Stretch the supplied 3" wide x 3-1/2" sleeve
and #56 clamps onto the Mass Air Flow sen-
sor. Attach the inlet duct to the MAF and to
the previously installed bypass valve hose.
E. Connect supplied 3/8 hose from the elbow
installed in the plastic inlet duct to the pas-
senger side valve cover breather hose using
the supplied 3/8" hose and hose mender.
F. Install the supplied flex hose and #52 clamps
from the plastic air inlet duct to the aluminum
supercharger inlet duct.
G. Tighten the clamps on each connection.
Tighten the T-bolt clamp until the supercharg-
er inlet is tight.
16. INLET DUCT INSTALLATION
NOTE: The air temperature sensor should be installed up
stream of the valve cover breather. Verify that the air
temperature sensor wires will reach the new location
and that there will be room for the sensor after the
inlet duct is installed.
