8. AIR INLET ASSEMBLY
A. Install the MAF sensor removed in section
one into the supplied MAF housing using
the original screws. Note that it only installs
one way (Do not force it). Air flow direction
is indicated on the sensor.
B. Verify that the supplied cast aluminum inlet
duct has two grommets installed. Install the
90° plastic elbow into the 3/8"ID grommet.
Attach the supplied 3/8" hose to the open
end of the elbow. Install the bypass valve
discharge barb into the 1" grommet. (See
Fig. 8-a.)
C. With the supplied T-bolt clamp encircling it,
install the duct onto the supercharger inlet
and point it towards the driver side.
D. Attach the air filter assembly to the Ø4" end
of the supplied MAF housing and tighten the
clamp. Make sure that the MAF plug is ori-
ented so that it will point towards the engine
when installed. Attach the short leg of the
supplied Ø3.5" plastic elbow to the MAF
using the Ø3.5" x 2" long sleeve.
E. Attach the longer leg of the plastic elbow to
the supercharger air inlet duct using the 3"
long sleeve. Orient the assembly so that
there is sufficient clearance to accommo-
date engine movement and tighten the
clamps. (See Fig. 8-b.)
F. If the MAF plug will not reach the sensor:
carefully cut, strip and lengthen the MAF
wires with the supplied wire and connectors.
Attach the MAF plug to the installed sensor.
G. Attach the supplied 3/8" x 39" hose from the
inlet duct to the passenger side valve cover
where the breather hose was removed in
Section 1.
H. Trim the supplied 1" 90° hose to attach the
barb on the supercharger discharge to the
inlet of the bypass valve. Tighten supplied
hose clamps on each of the connections.
(See Fig. 8-c.)
I. Use the supplied 5/32" hose, 1/4" hose
reducer and TEE to connect the fuel rail
pressure sensor vacuum hose to the bypass
valve.
