THREAD LOCKER USE

We have provided a small tube of thread locker in your kit. Whenever you see the symbol above on a step of the instructions apply 1 small drop of the thread locker to the threads of the screws or bolts. This will keep your hardware from vibrating loose during rough driving. If the hardware ever needs to be removed, do so slowly to avoid having the inserts strip out from the plastic.


STEP 1

Be sure the engine is cool before starting!

With the ignition switched off and the parking brake set, disconnect the negative battery cable.

IMPORTANT: Failure to disconnect the battery for a minimum of 2 hours may cause the Check Engine Light to illuminate upon completion of the installation or subsequent operation.

DO NOT SKIP THIS STEP!

Using a 13mm socket, remove the rear airbox mounting bolt. Then carefully remove the coolant overflow tube from the reservoir and use the mounting bolt as a temporary plug for the tube.


STEP 7

Remove the other airbox mounting bolt using a 13mm socket. Carefully tip the airbox assembly away from the fender so that coolant isn’t spilt.


STEP 8

Pull the assembly out of the factory grommets and remove from the truck.

Note: You will have to remove the bolt from the rubber tube to fit through the airbox assembly.

STEP 10

Insert the OE rubber grommet and insert it to the Airbox (A) as shown.


STEP 11

For those concerned about minimal engine heat; insert the three Clip Nuts (T) over the holes on the bottom opening of the Airbox (A), insert the Box Plug (U) into the end of the Airbox (A). Attach using the supplied 1/4-20 Hex Screws (V) and Flat Washers (Y) from the inside of the Airbox using 5/16” socket or ratcheting wrench. For those seeking additional airflow, set the Airbox End Cap aside.
