Press the silicone step hose over the throttle body with
the 3” side facing up. Use the .040 power band to tight-
en the step hose over the throttle body and place the
.048 over the other end.
The intake is pressed into the step hose while the
intake bracket is aligned to the vibra-mount stud.
The plastic clip has been pulled and the air resonator
box is now ready to be pulled out of the engine com-
partment.
The vibra-mount should sit flush to the air box brace
as shown above.
Once you have disconnected the air intake duct from
the air box cleaner and the throttle body, the vacuum
switching valve should be connected to the vacuum
lines as shown above.
The plastic clip has been popped out and pulled from
the locating hole.
Unscrew the bolt underneath the vacuum switching valve
that is seated on the air duct metal bracket. Once you have separated the air duct and vacuum
switching valve, continue to pull the air duct from the
engine compartment.
Once you have removed the small bolt, continue to
remove the vacuum switching valve from the metal
bracket.
Removing the resonator air scoop: Using a screw-
driver, pop the plastic clip from the crossmember sup-
porting the resonator air scoop.
align the vibra-mount stud to the air box brace.
Screw it into the pre-tapped hole located nearest to
the firewall.
Lower the primary intake into the engine compart-
ment and press the throttle body end into the step
hose.

The intake should be sitting firm in the step hose
while the intake bracket is aligned to the vibra-mount
stud.
Press the crankcase vacuum hose over the intake
port and use the stock clamp to secure the vacuum
hose to the intake port.
Press the 3” straight hose over the end of the primary
intake. Place two .048 power bands over the straight
hose. Tighten the clamp placed over the primary
intake for now.
Remove the m6 bolt from the front crossmember
holding the ground cable in place. Once the m6 bolt
has been removed, continue to remove the ground
cable to be relocated on the air box bracket.
The intake bracket is aligned and sitting flush with the
vibra-mont stud. The m6 flange nut and washer is used to fasten the
intake bracket to the vibra-mount stud.
The air filter is aligned and pressed over the intake
opening. The filter velocity stack should be butted up
against intake end.
Once the filter velocity stack and intake opening are
butted together, continue to tighten the filter clamp on
the filter.
Insert the m5 x 12mm hex screw under the VSV
mounting bracket while aligning the VSV over the
mounting bracket.
The vacuum switching valve is placed over the
mounting bracket while inserting the leading leg into
the slotted hole. Fasten the hex screw into the vacu-
um switching valve.
The grounding wire is removed and is relocated over
the air box bracket (A). The stock m6 bolt is used to
fasten the ground cable to the air box bracket (B).
This will allow you to move the negative battery
cable away from the secondary intake.
Align the vibra-mount to the cross member frame as
shown above (A) The vibra-mount is then screwed into
the frame until it sits flush over the frame (B).

Removing the resonator flex-hose: Pop the
first plastic clip on the side frame. The clip
attaches the flex-hose bracket to the frame.
A screwdriver is used to pop and remove the plastic clip (A).
The head on the plastic clip has been lifted and the clip is now
removed (B).
Removing the m6 bolt from the air intake resonator
bracket.
The secondary intake is inserted into the primary
intake hose as shown above.
The m6 flange nut and fender washer is used to fas-
ten the secondary intake to the vibra-mount stud.
Once the plastic clip and m6 bolt have been
removed, continue to pull the air intake flex-hose from
the front bumper.
The lower or filter end of the secondary intake brack-
et is aligned to the secondary vibra-mount stud.
The filter is now aligned to the end of the secondary
intake. The filter is firmly pressed over the end of the intake.
The end of the intake will press up against the filter
stop. Tighten the filter clamp once the filter has been
pressed up against the intake end.
The secondary intake bracket is aligned to the vibra-
mount stud.
Lower the secondary intake into the bumper area
while aligning the top end with the primary intake.

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.
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.
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.
