1. Disconnect the negative battery cables.
A.) Using a #20 Torx bit remove the two screws and
the Mass Air Flow sensor from the factory intake
tube.
B.) Loosen the hose clamp at the rubber coupler.
C.) Remove the factory filter minder and grommet
and save them for reinstallation in step # 7.
2. Rock the air filter housing back and forth while
lifting up, and remove the factory intake assembly
from the vehicle. There are only grommets holding it
in place.
3. Using a 10mm socket, remove 4 bolts, and remove
the factory air filter mounting plate.
4. Install the Airaid Cool Air Box (CAB) (#3) into the
vehicle as shown, replacing the factory air filter. Install three M6-1 x 25mm bolts (#9), and three flat
washers (# 7) thru the bottom of the CAB and into the
factory captured nuts. Leave the bolts loose for now.
5. Install two #72 hose clamps (#10) onto the urethane
hump hose (#4), and then slip the hump hose onto the
end of the factory turbo intake tube as shown. Leave
the clamps loose for now.

Washers
6. Slide the Airaid Intake Tube (#2) into the CAB
first, and then into the hump hose. If needed, the factory turbo intake tube can be adjusted for proper alignment. Next install four 1/4” button head bolts (#6),
and four flat washers (#7) thru the CAB to secure the
Airaid Intake Tube. Now tighten the three bolts at the
bottom of the CAB and the two hose clamps on the
hump hose.

7. A.) Reinstall the Mass Air Flow sensor into the
Airaid Intake Tube using two 8-32x 3/8” button head
screws (#8). Do Not Use The Factory Screws!
It may be necessary to reroute the MAF sensor wiring harness so that it will reach the proper location in
the tube.
B.) Next, reinstall the factory filter minder and grommet into the Airaid Intake Tube.
WARNING! If your vehicle has a Vehicle Emission Control Information decal affixed to the factory airbox, a
new replacement label must be obtained and installed in a readily visible position in the engine compartment in
order to remain CARB compliant. Failure to do so will prevent the vehicle from passing a smog check. Replacement labels can be ordered from your local dealership. Regulations state that the VECI label shall not be affixed
to any equipment which is easily detached from the vehicle. Label placement, under the hood on a painted surface is recommended.
8. The Airaid Premium filter (#1) is a very tight fit in
the CAB. For ease of installation, hold the filter in
your right hand, and guide the bottom of the filter
past the flange of the tube with your left hand inside
of the CAB. It will fit! Tighten the hose clamp.
Next install the weather strip (#5) on top of the CAB,
starting at the fender and working your way towards
the radiator.
9. Congratulations on the successful install of your
new Airaid Intake System!
Double check your work!
Make sure there is no foreign material in the intake
path. Make sure all clamps, hoses, bolts, and screws
are tight.
Reconnect the negative battery
cables!

Synthamax Air Filters do not require oil. Service air filter as needed by cleaning with common nonpetroleum 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.
