2002-2007 Dodge Ram Hood Airbox Installation Instructions Step 1. Disconnect the 5/8" black rubber hose from the factory box that sets directly in front of the throttle body that connects to the PVC valve. Leave the hose in place on the engine; you will tie back into it later. Step 2. Loosen the large hose clamps that are connected to the factory air intake, and then remove the mounting bolts that hold the center factory box in place. (Save hose clamps.) Step 3. Unplug the small sensor that is inserted into the center box by turning it and pulling outward. Leave it in place on the engine; you will reinsert it in to the round rubber grommet located on the Ram airbox later. Step 4. Remove the complete stock factory air intake system all the way back to the throttle body, including any O rings. Step 5. Located in the front and center of the engine is a 7/16" threaded bolt sticking out. Depending on what options your vehicle is equipped with you may temporary have to remove a bracket to get access to the bolt. Step 6. Attach the 10" long L shaped bracket that came with the air box to the two ¼" holes on the bottom of the box, with the short L part of the bracket pointing to the rear of the box using the 2 -1/4" bolts and lock washers. Step 7. Attach the 5/8" black rubber hose provided with the air box to the vehicles PVC valve hose connection, so that you can complete the connection once you have installed the air box in place. Step 8. Take the large black * see note: 3-1/4" x 8-1/2" hose provided with the Ram air box and place one of the hose clamps from your factory hoses on each end of the hose. Place a small amount of Vaseline on the inside the hose on each end. The hose fits very tightly, so you will need to put a great deal of pressure on the hose as you push it on to the throttle bottle using a twisting motion. Once you have it on turn it so that the stripe on the hose is faces down for the best appearance. Tighten the hose clamp at this point. Step 9. Loosen the 7/16" mounting bolt with the long threads near the alternator ( for the 5.7 cut the bracket off at the lower notch to shorten the fork 1”, then line up the short gooseneck on the air box with the hose from the throttle body and shove it into the hose using a wiggling motion till it is in place. Once it is in place tighten the large hose clamp, then connect the PVC valve hose to the 5/8" fitting at the rear of the box. Then push the small sensor into the rubber grommet in the Ram air box. Not all models have a sensor on 4.7, if it does, then drill a 5/8” hole into the 3.5” X 8” black hose in a position where the wire will reach. When you close the hood there should be 1/2 " to ¾" clearance between the air box and the hood. Step 10. Place some lubrication around the inside air box rim at the bottom to seal the K&N filter. Place the filter down into the box with the notched part down. Push it all way down till it locks under the small tabs around the rim.
