plastic fitting into the supplied 90

x 3.50” plastic inlet elbow. Attach the elbow to the
supercharger using the silicone sleeves and #56 hose
clamps.

B. Assemble the new air filter housing along with air filter

and end cap. Fit the end housing with the air filter
element provided, to the new filter housing. Secure
the end by drilling two 3/32” holes (transfer the hole
location from the end cover to the housing) and fasten

Fig. 7-a

C. Attach the factory MAF sensor to the new filter hous-

ing using the supplied silicone sleeve and #56 hose
clamps. The MAF sensor is directional, so make sure
that the “flow” arrow is pointed to the supercharger.
Connect the MAF to the supercharger inlet elbow with
the supplied length of flex hose and #52 hose clamps.

D. Install the factory air temperature sensor and grom-

met into the hole located in the plastic supercharger
air inlet elbow. Reattach the factory connector to the
sensor. Following

Fig. 7-b

, splice the supplied MAF

buffer in between the factory MAF plug and the MAF
meter. Mount the buffer unit inside the engine com-
partment on the inner fender using the supplied
Velcro strips. Make sure the unit is away from heat.
Removing the plastic nut retaining the main harness
to the firewall allows proper slack in the wire.

Install the supplied 3/4” vent adapter into the factory
rubber grommet located on the right side valve cover.
Rotate the vent adapter so that it points toward the
rear of the vehicle. Attach the 3/4" end of the supplied
180

rubber hose to the vent adapter. Attach the

supplied length of 5/8" hose and the 5/8" hose splice
to the 90

x 5/8” barb located on the top of the

supercharger inlet elbow. Connect the 180

rubber

hose to the inlet elbow hose. Trim excess hose length.
