1. Disconnect the negative battery cable!
Loosen the hose clamp on the flexible intake tube
at the airbox lid. Disconnect the breather hose going into the factory airbox lid. Slide the flexible
tube off of the lid and lift the airbox assembly
straight up and out of the vehicle. 2003 Models:
Disconnect the breather hose from the back of the
resonator.
2. Squeeze the tab on the connector and disconnect the intake temperature sensor wiring harness
on the front of the resonator. Next remove the two
bolts that secure the resonator to the engine. Lift
the resonator up at the front, and remove it from
the vehicle.
3. Remove the factory seal from the throttle body.
4. Using a 13mm socket, remove two bolts hold-
ing the airbox mounting bracket to the inner fender. These bolts will be reused in step #9.
7. Install the three grommets removed in step # 6
into the bottom of the Airaid Cool Air Dam (CAD)
(#3) at the locations shown here.
5. Gently twist the air temperature sensor counterclockwise and remove it from the resonator. The
sensor will be reinstalled in step #11.
Gasket
Filter Adapter
8. Install the adapter gasket (#25) and filter adapter
(#6) into the CAD using three 1/4-20 x 5/8” bolts
(#8) and flat washers (#9) as shown. Refer to the
line drawing above for reference.
6. Remove and save three grommets from the bottom of the factory airbox. They will be reused in
step #7.
9. Install the CAD into the vehicle by aligning the
grommets over the locating pins on the factory
airbox mount. Reinstall the factory bolts in the
fender that were removed in step #4. Next install
the 1/4”NPT x 1/2” barbed fitting (#19) into the
CAD.
2003 Models: Install the 1/4”NP T plug (#22) in
place of the barbed fitting.
10. Install the supplied reducing coupler (#4), onto
the throttle body using one #52 hose clamp (#10)
on the throttlebody and one #56 hose clamp (#11)
on the open end. Install the hump hose (#5) with
two #60 hose clamps (#12) onto the CAD.
13. 2003 Models: Reconnect the factory br ea th-
er hose using the 1/2” x 5/8” connector (#21) and
1/2” x 4 1/2” breather hose. Secure the ends with
the #16 speed clamps (#17), and the #22 speed
clamps (#18) as shown.
11. Install the supplied grommet (#13) into the
Airaid intake tube(#2). Next, carefully install the
factory air intake temperature sensor into the
grommet in the tube. Make sure it is fully seated

14. Install the Airaid Premium Filter (#1) onto the
tube on the filter adapter and tighten the clamp.
Next install the weather strip (#7) on the top of the
Quick Fit Panel as shown. (Hint: Start at one end
of the CAD and work your way towards the other

sliding the 3/4” x 2” hose (#24) over the factory
breather tube. Next insert the 1/2” to 3/4” barbed

the 1/2” rubber elbow (#15) between the 1/2”
barbed fitting on the CAD and the previous fitting.
Now slide the rubber cap (#14) over the nipple on
the Airaid intake tube and secure it with the #14
speed clamp (#16).

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.
