With the ignition switched off and the parking brake set. Disconnect the negative battery cable on the passenger side.
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!
Tools Required: Ratchet, 10mm Socket/Wrench.
Remove the two 10mm bolts holding the engine cover down. With the bolts removed, pull upwards and forwards to remove the engine cover from the vehicle.
Remove the Mass Air Flow Sensor connector from the sensor itself. Slide the gray locking tab away from the sensor and depress the tab to remove the connector.
Remove the bolt that secures the factory air box to the fender of the jeep. This bolt will be reused with the new S&B kit.
Loosen the hose clamp on the angled coupler at the end of the intake tube.
Remove the crimp clamp that attaches the Crank Case Ventilation (CCV) hose to the intake tube. You will not reuse this clamp so we recommend cutting it carefully to remove it. Be sure to only remove the clamp on the intake tube side of the hose. Remove the hose from the intake tube once the clamp is removed.
Remove the factory intake system from the vehicle.
Transfer the Mass Air Flow Sensor to the S&B intake tube by removing the two Torx screws. Install the Sensor into the MAF adapter plate (Item #7) and install the foam MAF gasket (Item #8) between the intake tube and the MAF adapter plate. Use the two provided phillips screws (Item #9) and tighten until the foam gasket is depressed.
Install the 90 degree bracket (Item #13) onto the airbox using the two allen screws and provided washers (Items #4 & #10) . Orient the bracket so the flat section with the single hole is facing the top of the airbox.
Install the Tube Seal (Item #6) into the S&B air box.
Install the CCV Grommet (Item #12) into the S&B intake tube. This grommet is a very tight fit to ensure a great seal so we recommend twisting the grommet into place and rotating it until the entire flange snaps into place. Then loosely install the hose clamp (Item #3) onto the grommet.
Install the CCV Venturi Tube (Item #15) into the CCV grommet. The notch in the tube must be facing the line on the grommet and line on the tube.. This tube is also a tight fit so we recommend using a socket and extension to help push the tube completely into the grommet. Push until the flange on the venturi tube makes contact with the shelf in the grommet.
Install the coupler (Item #5) onto the intake tube and install the hose clamps onto the coupler.
Verify the rubber grommets are still in place in the vehicle and did not pop out when removing the factory intake.
Install the S&B Airbox into the vehicle. The two prongs on the bottom of the airbox will fit into the rubber grommets shown in the previous step. Reinstall the bolt into the fender to secure the airbox.
Install the intake tube into the airbox and slide the coupler onto the turbo inlet tube. Tighten the hose clamps on the coupler.
Install the CCV tube into the S&B grommet and tighten the hose clamp.
Remove the protective film from the S&B air box lid.
Install the air box lid into the snap in lid seal and install it into the air box
Reconnect the Mass Air Flow harness to the sensor and slide the gray locking tab back into position once installed.
Reconnect the negative terminal on the battery.
Reinstall the engine cover and tighten the two 10mm bolts that hold it in place.
