This is pretty easy to do. Use a 4" hole saw on a drill to cut out the hole in the bottom of the airbox and in the lower mounting plate. For the scoop, I used an 3"x10" AC register I got at Home Depot. You run one end of the 4" flex duct up through the hole in the air box and connect the other end to the scoop. You have to cut the register at about a 45* angle to get it to line up with the lower gray valance under the bumper. The register has lips on it, keep one on the long sided edge of the register, you shove that part under the trucks frame when you line it up with the hole next to the passenger side fog light. I used a nylon strap with a velcro end looped up over the frame and under the scoop to hole it all in place. Hope thie helps!

Nice homemade duct work. I think i'm going to try something similar to that myself.

 

Thanks alot man, sounds like its not too hard, im going to try and do it in a few weeks once everything settles down around here. I was thinking about it some more last night and is there any chance that water can get in there and eventually to the engine since the intake is so low, like during heavy rain or driving through puddles, maybe i stupid question but i had to ask. Once again thanks for posting the pics and explaining it so well

 

I did a simular set up on mine awhile back. I used 2 4" floor drains i got a Home Depot and cut 2 holes in the air dam spaced about a foot apart in the center. I used 2-4" dryer vent tubes and ran them up to the bottom of the air box. I completly removed the metal plate, cuz its heavy and in the way. Then i cut the 2-4" holes in the bottom using my jigsaw. I used some 1/4 plastic sign board and covered the stock intake holes of the box. Then i ran the 2 tubes up into the box and used a full tube of black ATV and sealed everything. It looked sweet after i finnished it and painted the air dam. I could tell a big difference while cruising on the highway at 75mph. I would have to use almost no throttle to keep it moving, and gained speed fast with less throttle too. Sadly though, the only pics i have of this setup is the ones i took when i wrecked my truck. I do still have the airbox and tubes though, and i can take pics of them in July. I dont guess you'd care much to see them then though.

 

Your welcome! Water wasn't a real issue, you can see a wet spot in the pic of the 4" duct into the airbox. That was after a heavy rain and that's all that was there, the duct does go straight up for a little ways and that will prevent most water from getting it. I still used the two stock air inlets also, even if the scoop got sumerged in a puddle, the engine would still draw air from the two other inlets, I don't think it would pull water up the duct like a straw.

I found a scoop for my set up on my Ram too! I was on E-bay last night and someone just just posted a March Performance ram-air intake, it's for Mustangs though. It comes with an airbox (which I won't use), a length of 5" flex duct ( I may use) and most importantly, the scoop. Here's a link the March website that shows the intake. I think it will be perfect for my current set up. I got it for $45, it retails for like $170.
