Installation Step:
1. Disconnect the negative battery cable. Using a 5/16” socket or flat screwdriver, loosen the hose clamp that holds the factory airbox to the flexible intake tube.
2. Using a #20 Torx bit, remove 2 screws holding the Mass Air Flow sensor to the factory airbox tube. Remove the MAF and set it aside. Remove the factory filter minder and grommet from the factory airbox. Save them for later use in step #10.
3. Slide the flexible intake tube off of the factory airbox and then rock the airbox back and forth to free it from the mounting grommets, next lift it straight up and remove it from the vehicle.
4. Using a 10mm socket, remove 4 bolts from the factory airbox mounting plate. Remove the plate from the vehicle.
5. Assemble the two Cool Air Dam panels (#2) and (#3) as shown, using the five 6-32 screws (#10), washers (#11), and nuts (#12).
6. Install the Airaid intake tube (#4) into the Cool Air Dam using the three 1/4”-20×1/2” button head bolts (#6), and washers (#7) as shown.
7. Install the supplied rubber trim (#13) onto the Cool Air Dam as shown.
8. Install the Cool Air Dam into the vehicle where you removed the factory mounting plate in step #4, using the four supplied M6-1×25 bolts (#9), and flat washers (#7). Do Not Over Tighten the Bolts!
9. Reconnect the factory intake tube to the Airaid Intake Tube, and tighten the hose clamp.
