Screw the 8mm vibra-mount into the wheel well
mounting location until the vibra-mount is sitting snug
and flush over the mounting point.
Press the 3” straight hose over the throttle body.
Once the hose has been fitted over the throttle body,
continue to use two power bands over the hose and
tighten the band located over the throttle body.
Loosen and remove the two m8 bolts that secures the
resonator box to the fender well.
align the m8 vibra-mount to the pre-tapped hole located
over the wheel well. It may be necessary to use a
punch to drive a hole through the plastic liner under-
neath when installing the m8 vibra-mount.
Once the cover has been removed, continue to dis-
connect the 4mm vacuum line located behind the air
box cleaner.
Unscrew the two screws from the mass air flow
sensor, continue to remove the mass air flow sensor
from the air box cleaner.
Loosen the two flange nuts on the engine cover (A), then continue to remove the
engine cover off from the intake manifold. Unbolt the m6 bolt located on the
grommet below the air box cleaner (B).
Unbolt the second m6 bolt located on the top of the air box cleaner as shown
above. Removing these two bolt shown in figures one and two will allow you to
remove the entire air box cleaner.

The entire air box cleaner and resonator box is now
ready to be removed from the engine compartment. Remove the short 4mm stock vacuum hose from the
fuel pressure regulator. Press the new 18 inch, 4mm
vacuum line over the fuel pressure regulator port.

An m8 flange nut is used to fasten the power box bracket
to the vibra-mount stud.
Insert the three inch end of the intake into the throttle body hose (A). Once the
3” side has been positioned, continue to insert the 4” end into the power box
straight hose(B).
The intake is now aligned for the best possible fit. Once the intake has been
cleared from any possibility of rubbing, continue to tighten all nuts, bolts and
clamps.
Once the bracket and power box have been assem-
bled, the leg on the bracket will be located on the
radiuses side of the power box.
Press the 4” straight hose over the velocity stack
end. Use the two large power bands over the hose
and tighten the band located over the velocity stack
end.
Loosen and remove the two m6 x 65mm bolts that
secures the velocity stack base to the body. The second 65mm bolt is inserted into base and
body.

Align the power box bracket to the holes located on
the base, Use the same m6 x 65mm bolts to fasten
the bracket to the base.
Press the 18” -4mm vacuum line over the 3/16”
intake port as shown above.
Once the Power box is aligned to the intake end,
continue to tighten the flange nut to the vibra-
mount stud.
Lower the assembled power box into the engine
compartment. Insert the upper vibra-mount stud into
the hole located on the bracket.

Rub a dab of light oil around the MAFS O-ring,
then insert it into the sensor adapter. Be careful not
to pinch the O-ring when inserting it into adapter.
The stock breather hose is now aligned to the 5/8” intake
firmly press the hose over the intake port.
Use the stock self tapping screws to secure the MAFS to
the machined sensor adapter. The MAFS and electrical sensor harness have
been installed correctly.

You have purchased the Worlds first tuned intake system available anywhere. The Power-Flow intake system features
Injen’s patent pending MR Technology used to tune the intake and Power-Flow box. With Power-Flow, calibrating of the MAF
sensor is not required because the intake system comes tuned for use. Use only Injen replacement filters. The use of any
other filter will change the air/fuel ratio that can cause damage to your engine.
Once the breather hose has been properly installed
over the 5/8” intake port, use the wire tension clamp
to secure the breather hose in place.
Press the electrical sensor harness over the MAFS
until you hear the two devices snap together.
Place the cover in the engine compartment and over the intake. Draw a
line in the area that will be cut in order to get the cover to fit over the intake. Use a grinding wheel , dremel or utility knife to cut the corner section of the
engine cover.
One the engine cover has been fitted and cut along the edge, continue to
install the cover back to its original location and use the stack nuts to secure
the cover in place.
Congratulations! You have just completed the installation of this intake
system. Periodically, we recommend that you check the fitment of the intake
for any shifting of the intake that may cause rattling or rubbing.

Assembly and disassembly instructions for the Power Box for the purpose of cleaning screens and filter.
Unbolt the four- 65mm screws from the velocity
stack base located on the corners of the base. Once the screws have been removed, gently pull
the base out of the Power-box body. Unbolt the four- 12mm screws from the velocity
stack base located to the center of the base. Now
separate the base from the velocity stack.
Loosen the clamp on the filter neck in order to
separate the filter and velocity stack. Once the clamp has been loosened, gently
separate the velocity stack from the filter neck. With the velocity stack base out of the way, the
rectangular pre-filter screen will now slide out of the
Power-box channel.
Unbolt the four-45mm screws from the Power-box
top. The screws are located towards the corners of
the top.
Once the screws have been removed separate the
top stabilizer from the Power-Box body. The round pre-filter screen will now detach itself from
the stabilizer top for cleaning.
1. Upon completion of the installation, reconnect the negative battery terminal before you start the engine.
2. Align the entire intake system for the best possible fit. Once the intake has been properly fitted continue
to tighten all nuts, bolts and clamps.
3. Periodically, recheck the alignment of the intake system and make sure there is proper clearance around
and along the length of the intake. Failure to follow proper mainentance procedures may cause
damage to the intake and will void the warranty.
4. Start the engine and listen carefully for any odd noises, rattles and/or air leaks prior to taking it for a test
drive. If any problems arise go back and check the vacuum lines, hoses and clamps that maybe causing
leaks or rattles and correct the problem.
5. Check the filter for excessive dirt build up. Clean or replace the filter with an original Injen filter (can be
bought on-line at “injenonline.com”). Congratulations! You have just completed the installation of the best
intake system sold on the market. Enjoy the added power and performance of your new intake system.
