Carefully place the Airbox (M) and the Air Inlet Tube (S) in the general location. You may have gently push some hoses aside to drop both parts in at the same time.
Using the OE bolt, secure the Airbox (M) to the frame. Leave loose for now.
From inside the wheel well, attach the airbox to frame using the supplied M8x40mm Hex Bolt (K) and Fender Washer (L). Then secure both bolts mounting the airbox to the frame.
Insert the Air Inlet Tube (S) onto the Airbox (M) and secure using the supplied 1/4”-20x3/4” Screws (V), 1/4” Lock Washers (U) and 1/4” Flat Washers (W).
Reinstall the wheel liner using 6 of the OE screws. Reinstall wiring harness connector into wheel liner that was removed in Step #8.
Secure the wheel liner to the airbox using two supplied 1/4”-20x3/4” Screws (V) and Flat Washers (W) inside the airbox. Use the 1/4” Nylock Nuts (X) and 1/4” Flat Washers (W) under the wheel liner.
Insert the S&B Filter (J) onto the Adapter Tube (H) and secure the #104 Hose Clamp (I). Install the assembly into the Airbox.
2004-08 Models: Push the OE breather hose onto the stem of the Adapter Tube (H).

Install the Clear Lid (N) using the supplied 5/16” SS Screws (Q) and Rubber Washers (R) along with the 10-24 Screws (P) and SS Sealing Washers (O). This will secure the Filter Adapter to the Airbox as well. (Do not over tighten!)
Note the OE Temp. Sensor orientation. Then carefully turn it counterclockwise and pull it out of the OE resonator. Then remove the O-ring from the sensor.
Insert the supplied Grommet (D) into the Intake Tube (E). Carefully push the Temp. sensor into the grommet using a twisting motion. Be sure to match the OE orientation.
Place a #72 Hose Clamp (F) over each end of the Hump Coupler (G). Then slide the hump coupler over the end of the Intake Tube (E).
Secure the Silicone Step Coupler (B) to the throttle body using a #56 Hose Clamp (A). Place the #60 Hose Clamp (C) around the top of the Silicone coupler.
Insert the Intake tube assembly into the Silicone Coupler, then slide the Hump Adapter over the Adapter Tube. Tighten all hose clamps when you are satisfied with the positioning.
Reconnect the Temp. Sensor wiring harness.
Reconnect the battery. Inspect your installation, make sure the kit is properly positioned and all fasteners are secure. Affix the CARB sticker (if applicable) near the intake kit. The installation is now complete.
