Note: The installation of this cold air intake does require mechanical skills. Removal of the front bumper requires
loosening and removing several plastic plugs and screws that may be difficult. In addition to removing the
bumper, you will also have to remove the air resonator box, battery and tray when beginning this installation.
Injen strongly recommends that this system be installed by a professional mechanic.

Firmly pull down and out to remove air resonator box.
This may require some aggressive pulling when remov-
ing the resonator box.
Proceed to remove the second 10mm bolt as shown
above. Do not remove the air box just yet.
Drivers side fog light harness is now removed. Pull and
remove the entire front bumper and place it to the side. Remove the second 10mm bolt. Now the air res- onator box is ready for removal.
Picture shows removing phillips screw from bumper Unclip the fog light harness from the bulbs on the
passenger and driver side bumper. (Passengers
side is shown above)
Stock air box cleaner shown in this picture Remove screw on each side of the front bumper using
a phillips screw driver
Remove front bumper. Gently pop plastic clips up
using a flat head screw driver as shown above (B).
There are 7 plastic clips on top and 10 plastic clips
on the bottom of the bumper (A).
Firmly pull the sides of the front bumper outward until
the bumper unlatches from the clips located below the
headlights.
With the front bumper removed, you can now access
the air resonator box located on the driver side. Use a
10mm 3/8 socket and ratchet to remove the first
10mm bolt.
The upper air box is secured with two 10mm bolts.
Remove the first one as shown above.

The entire air box and air duct can now pulled out of
the engine compartment Proceed to remove the coolant line as shown. A little
coolant may spill out, which can just be wiped up with
a shop rag.
Again with the pliers, loosen the spring clamp that
secures the PCV breather to the valve cover. Disconnect the air box duct from the throttle body.
Use a 10mm 3/8 socket and ratchet to loosen clamp on
the factory air duct connected to the throttle body. Pull the steel PCV breather tube out of the factory air
box duct.
Now you can unplug the harness from the air mass sen-
sor. Carefully, pull the air mass sensor from the factory
air box, this will also be use later.
Using a phillips screw driver, unscrew two phillips
screws from the air mass sensor. Place these phillips
screws to one side because you will be reusing these
later.
Use a pair of pliers to loosen the spring clamp that
secures the PCV breather tube as shown.
Then remove the PCV breather from the valve cover.
IMPORTANT!!! Make sure the vehicle has cooled
down before doing these next steps.
Remove the spring clamp from the coolant line just
under the throttle body as shown.

Again with the pliers loosen the spring clamp and
detach the coolant hose from the thermostat housing
as pictured.
Using a spring clamp saved from the last step attach
one end of the included 10mm hose to the thermostat
housing coolant port, replacing the hose from figure
27.
Once the step hose is placed onto the throttle body,
you can tighten the .040 clamp only (throttle body
Side). Leave the 048 clamp loose for now.
The vibra-mount is aligned to the pre-tapped hole as
shown above.
Figure 28 shows the coolant line that was just
removed. Retain the two spring clamps from the coolant line as
it will be reused in the next step.
With the second spring clamp saved. Attach the
other end of the 10mm hose to the coolant port under
the throttle body, replacing the line hose from figure
25.
Place one .048 clamp (X-4004) and one clamp
(X-4003) clamp over the step hose. Press the 2 3/4”
end over the throttle body.
Use a 10mm socket and 3/8 ratchet to remove the
lower 10mm bolt attaching the support bracket on the
driver side shock tower.
Remove the 10mm bolt, this is where the vibra-mount
will be installed.
The vibra-mount is screwed in until it sits flush with
the strut tower mount. The secondary vibra-mount is now aligned to the pre-
drilled hole located on the resonator opening as
shown.

Place the primary tube (longer tube) into the wheel
well opening. Make sure the air mass sensor adapter
side is on the top side.
Press the tube with the air mass sensor side into the
2 7/8” X 3 1/4” step hose.
Line the primary intake bracket to the vibra mount
stud located on the shock tower mount.
Insert the factory air mass sensor in the the billet
adapter as shown.
The electrical harness clip is now pressed over the
mass air flow sensor. Press firmly until it snaps in
place.
Use one fender washer (X-6010) and one M6 nut (X-
6002) to secure the bracket to the vibra mount.
Reuse the two screws that secured the air mass sen-
sor to the factory air box.
Place two clamps (X-4004) over the 3” hose. Press
the 3” hose over the end of the primary intake. use a 8mm nut driver to tighten the clamp over the
intake end.
Tighten the two screws securing the air mass sensor
the the billet adapter.
Use a 10mm 3/8 socket and ratchet to tighten the M6
nut to the vibra mount.

The secondary intake is lowered into the resonator
opening and aligned to the primary intake. The secondary intake is now pressed into the 3” hose
located on the primary intake. As the secondary intake is pressed into the 3” hose,
the intake bracket is aligned to the vibra-mount stud.
The remaining fender washer and m6 flange nut are
used to secure the secondary intake. Tighten the m6 flanged nuts to secure the intake
brackets to the vibra mounts. The 15mm hose is pressed over the crankcase vacu-
um port.
The filter is now aligned to the end of the intake.
The 15mm hose is now installed.The remaining end of the 15mm hose is pressed
over the intake port.
And reattach the front bumper.
Now reattach the fog light bumper harness to the har-
ness on the car.
Once the intake end is sitting flush to the filter stops,
continue the tighten the filter neck clamp.

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 maintenance 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.
Align the entire intake for best possible fit. Once you have aligned and made
sure that the length of the intake is free from any moving parts, continue to
tighten all nuts, bolts and clamps.
Congratulations! You have just completed the installation of this intake system.
Periodically, check the alignment of the intake, normal wear and tear can cause
nuts and bolts to come loose. Failure to check the alignment and adjust the
intake can cause damage that will void the warranty.

5. Check the filter for excessive dirt build up. Clean or replace the filter with an original Injen filter.
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.
