How to Install S & B Cold Air Intake w/ Dry Extendable Filter (97-06 4.0L Wrangler TJ) on your Jeep Wrangler

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

2. Remove the crossbar by removing the two bolts holding it in place.

3. Loosen the hose clamp at the throttle body and lift the tube from the inlet.

4. Pull and remove the hose from the stock intake and valve cover fitting completely. Note: If you have model year 2005-2006 and have an IAT sensor, disconnect the wiring harness and remove the IAT sensor.

5. Remove three nuts securing the stock air box located under the passenger side wheel well.

6. Lift up and pull the stock intake out. It should come out as one piece.

7. Install the Hose Barb (N) into the side of the Air Tube (H) until finger tight, then turn it one to two complete turns with a wrench.

8. Install the Grommet Plug (S) into the side of Air Tube (H). Note: If you have model year 2005-2006 and have an IAT sensor, you must install the Grommet (R) with the 1/2” ID hole.

9. Install Coupler (I) onto the Air Tube (H) on the throttle body side. Tighten the #52 Hose Clamp (K). Leave the #44 Hose Clamp (J) loose.

10. Install the Coupler (G) with the two #88 Hose Clamp (L) and connect Air Tube (F&H) together. Tighten both hose clamps.

11. Install the Rubber Cuff (E) with the #104 Hose Clamp (M) on the Air Box (A). Tighten the hose clamp.

12. Lower the Air Box (A) as shown and align the three holes on the box with the holes on the fender. Note: The fourth hole is for water drainage.

13. Use the hardware (T, U, and V) provided to secure the Air Box (A). The washers go in the air box and under the fender. If necessary you will have to use a two wrench method to tighten the down the air box. One wrench on the nut and one on the head of the bolt.

14. Insert the Air Filter (B) into the Air Box (A). Make sure the hose clamp is accessible. Push the connected Air Tube (F&H) through the Rubber Cuff (E) until you can slip on the air filter. Tighten the #88 Hose Clamp (L) at the air filter to secure the air filter to the tube.

15. Install the other end of the Air Tube (H) onto the throttle body. Make sure that the coupler is seated properly on the throttle body. Tighten down the #44 Hose Clamp (J). Note: If equipped install the IAT sensor into the Grommet (R). Seat the sensor into the grommet until the O-ring is not visible and reconnect the wiring harness before installing the air tube onto the throttle body.

16. Connect the Breather Hose (O) from the Hose Barb (N) to the fitting on the engine. If necessary, you can use a little motor oil on the fittings to aid installation.

17. Install the Lid Seal (C). Put the two ends of the seal in the groove next to each other, then push in the rest of the seal into the groove.

18. Remove the protective covering from the Lid (D). Place the lid on top of the Air Box (A) and secure the lid using the four provided Screws (P) and Washers (Q). Do not over-tighten.

19. Reinstall the crossbar and bolts.

20. Reconnect the battery. Inspect your installation, make sure the kit is properly positioned and all fasteners are secure. The installation is now complete.

Warning! If your vehicle has a Vehicle Emission Control Information decal affixed to the factory airbox, a new replacement label must be obtained and installed in a readily visible position in the engine compartment in order to remain CARB compliant. Failure to do so will prevent the vehicle from passing a smog check. Replacement labels can be ordered from your local dealership. Regulations state that the VECI label shall not be affixed to any equipment which is easily detached from the vehicle. Label placement, under the hood on a painted surface is recommended.
