11. AIR INLET

A. Using the supplied 1/4-20 hardware, mount the

MAF meter to the Vortech MAF bracket and
secure. (See

Fig. 11-a

for orientation.) Remove

the factory MAF screen before attaching the
meter to the new bracket.

B. Slide the supplied orange sleeve onto the MAF

outlet to function as a spacer for the 3-1/2" blue
sleeve.

C. Attach the supplied K & N air filter, 3-1/2” sleeve,

3-1/2” elbow and #56 hose clamps to the

MAF and secure.

D. AIR INTAKE TEMPERATURE SENSOR:

• 1994-95 Models:

Thread the temperature

sensor into the Vortech MAF bracket.

• 1996-1998 Models:

Plug the Vortech MAF

sensor threads with the supplied 3/8 NPT plug.
Drill a 9/16" hole into the side of the plastic air
inlet elbow (see

Fig. 11-a ). Insert the factory

temperature sensor and supplied grommet into
the 9/16" hole. Lubricate for easier fit.

• 1999-2000 Models:

Plug the Vortech MAF

sensor threads with the supplied 3/8"NPT plug.

E. Working from beneath the vehicle, remove the

two factory nuts and washers from the right side
lower fender valence. Mount the MAF/bracket
assembly onto the existing studs using the same
washers and nuts originally removed. (See

Fig.

11-a.

)

Using a #52 hose clamp, connect the piece of

3-1/2” flex hose to the elbow attached to the MAF
meter and route it through the opening in the right
side inner fender toward the supercharger. Make
sure the 3-1/2” flex hose does not contact or rub
on the edge of the inner fender opening. Eventual
hose failure will result if hose is not properly
routed. (See

Fig. 11-b

G. Route the factory temperature sensor and MAF

sensor connectors out through the inner fender
opening. Reattach the connectors to the relocated
sensors.

1996-1998 Models:

Attach the supplied piece

of rubber 3/8" hose to the end of the factory valve
cover breather tube (plastic). Into the end of the
rubber breather hose, insert the factory 3/8" x 90

plastic breather fitting to allow connection of the
tube assembly to the supercharger air inlet duct.
(See

Fig. 11-c.)

1996-1998 Models:

Using a short piece of

3/8" rubber hose, join the plastic 90

elbow to the

3/8" brass barb on the supercharger air inlet duct.

1999-2000 Models:

Attach the supplied piece

of 3/8" rubber hose to the factory valve cover
breather, located on the passenger side valve
cover. Connect the other end of the previously
installed hose to the 3/8" brass barb on the
supercharger air inlet duct.
