Clip
1. Disconnect negative battery cable.
Remove the grey security clip on the bottom of
the Mass Air Flow sensor wiring connector. Next
squeeze the tab on the bottom of the connector,
and disconnect the wiring harness from the sensor. Now loosen the hose clamp holding the tube
to the throttle body.
4. Using a #20 Torx Bit, remove the two factory
screws that hold the MAF sensor into the factory
intake tube. Remove the MAF sensor for reinstallation in step #7.
2. Squeeze the tabs on the sides of the crankcase
breather connector, and disconnect the breather
hose from the factory intake tube breather fitting.
5. Remove the factory breather fitting from the
factory intake tube and save it for reinstallation in
step #6.
Grommet Post
3. Lift up on the factory intake tube assembly to
disengage the grommets from the three grommet
posts and throttle body. Remove the assembly
from the vehicle.
6. Install the provided grommet (#13) into the
hole in the Airaid Intake Tube (#2). Next install
the factory plastic breather fitting removed in step
#5 into the grommet.
7. Reinstall the Mass Air Flow sensor removed in
step #4, into the Airaid Intake Tube using two 832x3/8” button head bolts (#7).
Do Not Use The Factory Screws!
Next, install the urethane coupler (#3) onto the
Airaid Intake Tube using two #64 hose clamps
(#12) as shown. Tighten only the clamp closest to
the MAF sensor.
Driver Side Shown
8. Attach the two air dams (#5 driver side & #4
passenger side) onto the Airaid Intake Tube using
one 8-32x1/4” button head bolt (#8) and #8 flat
washer (#9) on each side. Leave the bolts slightly
loose for now to allow for adjustment.
9. Using a flat blade screwdriver, pry up the center pin in the grommet post closest to the right
fender on the radiator shroud, and remove both
pieces of the grommet post from the vehicle.
Grommet Posts
10. Set the Airaid Premium Filter into the area in
front of the radiator. It will be mounted in step #
15.
13. Slide one clip nut (#10) over the outside end
of the plastic radiator cover and align it with the
hole in the air dam. Install one rubber washer
(#11) over the threads of the clip nut, and then
align the air dam hole over the washer. Add one
more rubber washer, one #8 flat washer (#9), and
one M4 Pan Head Screw (#8) to secure the air
dam. Repeat this step on the passenger side. Refer
to the line drawing on page one.
11. Install the provided grommets (#15), narrow
side down, into the Airaid Intake Tube as shown.
Make sure that they are seated all the way into the
bottom of the holes.
14. Tighten all four button head bolts that secure
the air dams to the intake tube, and the radiator
shroud.
12. Install the Airaid Intake Tube assembly onto
the throttle body first, and then align the grommets over the factory grommet posts on top of
the radiator shroud. Push down on the grommets
to seat them on the posts. (Hint: Use a 1/2” deep
socket to help seat the grommets onto the posts.)
Now tighten the hose clamp on the throttle body.
15. Slide the Airaid Premium Filter up onto the
end of the intake tube and tighten the clamp. Reconnect the MAF sensor wiring harness and re-
place the grey security clip. Reconnect the factory
breather hose to the breather fitting. Install the
weather strip (#6) onto the top of the air dams as
shown.
16. Double check your work!
17. Reconnect the negative battery cable!
Make sure there is no foreign material in the intake path. Make sure all clamps, hoses, bolts,
and screws are tight.

Synthamax Air Filters do not require
oil. Service air filter as needed by
cleaning with common non-petroleum
all-purpose household cleaner and water. Simple Green®, Formula 409® or
equivalent works great. Apply cleaner
to outside of air filter and allow to soak.
Then flush filter clean from the inside
out with a garden hose and repeat steps
if necessary. Do not apply high pressure water or air to clean filter. Allow
filter to air dry and reinstall.
