Section 2: Stock Intake Tube Removal

Use caution when working in the engine compartment. Make sure the engine has been OFF for several hours and cool. Some components from the stock air intake system will remain in service. Take care when removing stock air intake components to not damage them.

1. Disconnect negative battery cables. (both batteries)

NOTE: Wait for 15 minutes before proceeding to allow the ECM to fully discharge.

Disconnecting sensors before the ECM is fully powered down can result in Check Engine Codes or starting in “Limp Mode” after install is complete.

2. Remove OEM intake scoop cover

There are 12 plastic clips. Use a plastic panel popper tool to avoid damage to the cover.

Note: 2 are located behind the scoop.

Save the clips to be reused.

3. Disconnect the two sensors located on the intake housing lid.

a. First slide the harness clip free from the housing lid.

b. Then pull the retainer clip holding the harness to the scoop using a panel popper.

c. Pull the harness clear of the intake.

4. Detach the OEM scoop from the truck

Remove the two bolts on either side of the scoop. Use a 10mm socket and ratchet.

5. Separate scoop from the intake housing.

Note: The scoop will be reused with the Banks Ram-Air system.

6. Detach the intake tube from housing

Use a 5/16” nut driver or screwdriver to loosen the hose clamp holding the intake tube onto the housing lid.

7. Remove housing and scoop

Pull the intake housing and scoop out of the engine bay.

8. Remove the intake tube

Loosen the hose clamp holding the intake tube onto the turbo. Use a 5/16” socket with an extension and ratchet or 5/16” nut driver.

Section 3: Installing the Banks Ram-Air Intake

9. Transfer the (MAF) and (TMAP) sensors onto the Banks tube.

Note: Use the supplied M4 screws and o-ring when installing sensors on the Banks Tube.

10. Transfer grommets to the Banks Ram-Air Intake housing.

There are three grommets that need to be transferred from the factory intake housing to the Banks Ram-Air Intake housing

11. Drop the housing into place.

Make sure that all three grommets are seated.

12. Attach hose to turbo.

Slip the Banks hose onto the turbo with the arrow aligned to the breather hose on the turbo.

Note: Make sure the internal grove of the hose clears the end of the turbo inlet.

13. Slip clamps onto the hose.

Tighten the hose clamp on the turbo side. Leave the outer clamp loose.

14. Insert the Banks filter.

Insert filter into the Banks housing and place the large hose clamp over the filter cuff.

15. Slip the Banks intake tube into the filter cuff.

Do not tighten the clamp.

16. Slip the opposite end of the tube into the hose on the turbo.

Note: Make sure the alignment arrow on the hose, lines up with the dimple on the Banks intake tube.

17. Check the alignment of the tube:

a. The filter base should be parallel to the housing opening.

b. The sensors should have proper clearance.

18. Tighten the clamp on the Banks intake tube hose.

Check that the alignment arrows are still pointing at the dimple on the Banks intake & the breather hose on the turbo.

19. Plug in the MAF and IAT sensors.

20. Check harness clearance.

Make sure the sensor harness is tucked against the intake housing and away from moving parts.

21. Reinstall the factory scoop.

First, slide it over the Banks’ Super Scoop. Then, position it into place and reinstall the two bolts on either side of the scoop.

22. Reinstall the scoop cover.

Use the original clips.

23. Install the Banks window onto the housing.

Use the supplied thread locker with the four Philips head screws.

Note: Do not over-tighten the screws. They should only be snug. The thread locker will prevent them from coming loose.

24. Re-connect negative Battery Terminals.

Verify terminals are attached firmly to prevent corrosion or electrical faults.

Start your truck and enjoy your new Banks Power Ram-Air intake.
