1. Disconnect negative battery cable.
Push the tab on the factory breather hose and discon-
nect it from the fitting in the factory coupler. Loosen
the three hose clamps on the factory intake tube. 2. Lift the factory intake tube up and remove the
Mass Air Flow (MAF) sensor fr om the coupler and
slide it out of the way. Next remove the coupler from
the throttlebody, and then remove the factory intake
tube and filters from the vehicle as an assembly.
5. Remove the two factory grommets from the facto-
ry intake tube. They will be reused in step #6.
3. Remove the barbed fitting from the factory cou-
pler. It will be reused in step #4.
4. Reinstall the barbed fitting removed in step #3 into
the Airaid hump hose (#3) as shown. Install one #64
hose clamp (#14) onto the back of the hump hose,
and one #60 hose clamp on the front. 6. Install the factory grommets removed in step #5
into the Airaid intake tube (#2).
7. Attach the two air dams (#s 5&6) to the Airaid
intake tube as shown using two 8-32 x 3/8” screws
(#8), and two #8 flat washers (#10). Leave the screws
slightly loose for adjustment later. Refer to the line
drawing at the top of this page for reference.
Next install the supplied coupler (#4) onto the Airaid
intake tube as shown using two #60 hose clamps
(#13). Tighten only the clamp on the tube. 8. Install the Airaid Premium Filter into the area in
front of the radiator. It will be attached to the Airaid
intake tube in step #11. 9. Install the hump hose with the #64 hose clamp on
the throttlebody. Adjust it so that the breather hose
aligns with the barbed fitting, and reconnect the
breather. Tighten the hose clamp on the throttlebody.
Reinstall the MAF sensor into the hump hose making
sure the “Flow” arrow is pointing towards the engine.
