1. Disconnect the negative battery cable.
A.) Loosen the hose clamp on the factory intake tube
at the throttlebody. B.) Disconnect the crankcase
breather tube from the factory air intake tube. C.) Dis-
connect the idle bypass hose from the factory air in-
take tube and remove the hard plastic 3/4” coupler
from inside the rubber hose. 2. A.) Loosen the factory intake tube hose clamp on
the Mass Air Flow (MAF) sensor housing. B.) Care-
fully remove the intake air temperature sensor from
the factory intake tube(1999-01 models). C.) Using
the supplied T-20 torx bit, remove two screws, and
remove the MAF sensor from the MAF housing. Set
the temp sensor and MAF sensor to the side for rein-
stallation later. 3. Remove the bolt that holds the factory air filter
canister to the inner fender. Next remove the factory
air intake tube from the throttlebody, and then the
MAF housing. Now with a twisting motion r e-
move the factory air filter canister from the vehicle.
4. Remove the two factory grommets from the bottom
of the factory air filter canister and reinstall them into
the holes in the inner fender. 5. Remove the four bolts that hold the MAF housing to
the factory air filter canister. The bolts will not be re-
used, but the MAF housing will be used in the next
step. 6. Mount the factory MAF housing to the Airaid Cool
Air Dam (#6) using four 6mmx25mm bolts (#8),
four lock washers (#10), two MAF gaskets (#12), and
one velocity stack (#3). Refer to the line drawing at
the top of this page for the proper sequence of how to
install the parts.
8. Install the reducer coupler (#4) onto the throttle-
body end of the Airaid Intake Tube using the #56
hose clamp (#14) on the tube end, and the #44 hose
clamp (#13) on the small end. Tighten only the large
#56 clamp at this time.
