Using a 10mm socket, remove the two bolts securing the factory intake tube to the vehicle’s fan shroud. (Figure 2) These will not be reused.

Step 8

Using a 10mm socket, remove the bolt securing the factory intake box to the inner fender. This bolt will be reused.

Step 9

You can now remove the complete factory intake from the vehicle. Grip the intake muffler with your right hand and make sure that it is free from the turbo inlet hose. Grip from the opening of the factory intake housing with your left hand. Lift up until the two grommets holding the bottom of the housing onto the vehicle release. Be careful not to break the tab holding the radiator fan connecter to the fan shroud.

Step 10

Remove the two grommets from the legs on the bottom of the factory intake housing. They will be reused with the Banks Ram-Air system. See Figure 4.


Section 3: Installing Banks Ram-Air System

Step 1

Insert the factory grommets into the two holes in the vehicle. See Figure 5.

Step 2

Install the mounting pegs to the Banks Ram-Air Intake housing. Push the pegs out of the holes in the bottom of the housing and slide the retaining clips into the grooves. See Figure 6.

Step 3

Install the Banks Air filter into the Banks Ram-Air Intake housing.
See Figure 7.

NOTE: Make sure that the arrow on the filter is positioned towards the top and pointing down.

Step 4

Install the housing into the vehicle. Line up the pegs to the grommets and push down until you feel them pop into the grommets. 

Step 5

Install the supplied grommet into the IAT port in the Banks intake tube.

Step 6

Install the IAT sensor grommet into the Banks tube.

Step 7

Install the Banks intake tube by first inserting the larger end into the filter and then the smaller end into the OEM turbo inlet hose. Align the tab on the hose to the indent on the Banks tube. Align the arrow on the filter to the arrow on the tube. Tighten both clamps. 

Note: Take care not to pinch or trap the plastic lines under the tube. 

Step 8

Install the IAT sensor into the Banks intake tube. Position the locking tab in the 9 o’clock position. See Figure 8.

Step 9

Push the plastic lines onto the bright aluminum nipples of the Banks intake tube. See Figure 9.

Note: Make sure that the connectors click into place and lock.

Step 10

Install the factory bolt thru the Banks housing and into the inner fender. Make sure the housing is in place and the clearance around it is even before tightening the bolt. See Figure 9.

Step 11

Install the Banks window onto the housing using a Phillips screwdriver and the 4 supplied screws. Apply the supplied thread locker on the screws to prevent them from backing out over time. 

Note: Do not over tighten the screws. They will crack the window.


Section 4: Filter Maintenance

NOTICE: The Banks Ram-Air Oiled Air Filter comes pre-oiled and no oiling is necessary for initial installation. Use Banks Ram-Air Filter Cleaning System (part#90094), available from Gale Banks Engineering to service the Air FIlter. Follow the instructions included with the cleaning system to clean and re-oil your Bank Ram-Air Oiled Air Filter.

Step 1. PRE-CLEANING

Tap the element to dislodge any large embedded dirt, then gently brush with a soft bristle brush. 

NOTE: If complete cleaning is not practical at this time, reoil the element and reinstall it in your vehicle.

2. SPRAY-ON CLEANING

Spray air-filter cleaner liberally onto the entire element and let soak for 10 minutes.

3. PAN CLEANING

Large air-filter elements can be rolled or soaked in a shallow pan of air-filter cleaner. Remove immediately and let soak for approximately 10 minutes.

NOTICE: NEVER use gasoline, steam, caustic solutions, strong detergents, high-pressure nozzles, or cleaning solvents to clean the filter element. All of these can cause harm to the filter media as well as SHRINK and HARDEN the rubber end caps.

4. RINSING

Rinse off the element with low pressure water. Tap water is okay. Always flush from the clean side to dirty side. This removes the dirt and does not drive it into the filter.

5. DRYING

Always dry naturally. After rinsing, shake off all excess water and let the element dry naturally.

6. AEROSOL OILING

After cleaning air filter always reoil before using. Spray air filter oil down into each pleat with one pass per pleat. Wait 10 minutes and re-oil any white spots still showing.

7. OILING HINTS

Never use a Banks Ram-Air oiled filter without oil (the filter will not stop the dirt without the oil). Use only air filter oil. Air-filter oil is a compound of mineral and animal oil blended with special polymers to form a very efficient tack barrier. Red dye is added to show just where you have applied the oil. Eventually the red color will fade but the oil will remain and filter the air. NEVER USE Automatic Transmission Fluid. NEVER USE Motor Oil. NEVER USE Diesel Fuel. NEVER USE WD40, LPS, or other light-weight oils.

8. REINSTALL

Reinstall your Banks Ram-Air filter element with proper care. Make sure the element seats properly in the filter case. Install the cover making sure it’s in the right position. Tighten all the nuts, bolts, screws or clips to factory specifications.

9. DO NOT DISCARD

Affix the “Do Not Discard” sticker to the filter case (included with every Banks replacement element). Make sure you put the sticker in a highly visible place to alert your mechanic not to discard.

10. PERFORMANCE HINTS

Service every 50-100,000 miles on street-driven applications. Service more often in offroad orheavy-dust change the element whenthe air-filter restriction reaches 18”–H2O.

CAUTION: Extremely fine dust from agriculture or offroad use will pull the oil from the element. Frequent reoiling of the element’s clean side might be required. Completely service when practicable. For extra protection use an air-filter sealing grease on rubber ends of the element. Service only with air-filter cleaner and air-filter oil.

DRY FILTER CLEANING

Clean every 50-100,000 miles on

street-driven applications. Clean more often in offroad or heavy-dust conditions. If an air-filter restriction gauge is installed, then change the element when the air-filter restriction reaches 18”–H2O.

1. PRE-CLEANING

Carefully tap the air filter element to dislodge any large embedded dirt or debris.

2. CLEANING

Spray an appropiate DRY AIR-FILTER CLEANER SOLUTION liberally onto both sides of the entire filter element with the majority applied to the dirty side. Soak for 10 minutes. Do not allow the DRY AIR-FILTER CLEANER SOLUTION to dry on the air filter.

NOTICE: NEVER use gasoline, steam, caustic solutions, strong detergents, high-pressure nozzles, or cleaning solvents to clean the filter element. All of these can cause harm to the filter media as well as SHRINK and HARDEN the rubber end caps.

3. RINSING

Rinse the filter element with cool or warm (not hot) water from the clean side out in order to flush the dirt out of the filter. It may be necessary to use your fingers on the hose to apply light water pressure. Repeat steps 2 and 3, until the water flowing through the media is completely clear of any dirt and debris.

4. DRYING

After rinsing, gently shake off excessive water and allow to dry naturally Re-install the filter onto the intake system, airbox or custom assembly once it is dry or just slightly damp. Follow all original installation instructions.

5. REINSTALL

Reinstall your Banks Ram-Air filter element with proper care. Make sure the element seats properly in the filter case. Install the cover making sure it’s in the right position. Tighten all the nuts, bolts, screws or clips to factory specifications.

7. DO NOT DISCARD

Affix the “Do Not Discard” sticker to the filter case (included with every Banks replacement element). Make sure you put the sticker in a highly visible place to alert your mechanic not to discard.

8. PERFORMANCE HINTS

Service every 50-100,000 miles on street-driven applications. Service more often in offroad or heavy-dust conditions. If an air-filter restriction gauge is installed, then change the element when the air-filter restriction reaches 18”–H2O.
