I posted part of this in the HD forum recently, but this is a more comprehensive write-up on the mod.
Got the idea from a post of another forum. I don't want to **** of the mods by posting links to other Ram sites, but if you Google "Ram airbox intake tube mod" it's pretty much the first hit. Decided since I have already done a full exhaust, tune and TB on my 6.4, it would be worth a shot.
Basically you cut a 3" hole in the bottom of the air box and run a flex tube from it to the front of the truck somewhere. Some people have tried to use 4" hose but that would be insanely tight IMO. Highly recommend buying a 3" hole saw as it makes the job much easier. A cheap one is about $10 or so online, and well worth the time and aggravation it saves.
Used a 3" adapter from Spectre.

Originally just use some aluminum 3" dryer flex tube but then decided to go a little something a little more robust. I would recommend against the cheap dryer tubing as it comes apart and punctures pretty easily.

Along with an air scoop.

Basically you mount it up front in the grill area to catch some clean/cool air. I bought 6' of the air duct hose but really only use about half that, so 3' would be perfect IMO. I drilled another 3" hole in the plastic shroud between the radiator and headlamp in an area that wouldn't be blocked by the Ram grill crosshairs. To remove the grill you need to remove the top shroud first, then the grill is held in with 4 10mm bolts up top and some cheap push-type retainers on the side.
This is what you see looking through the wheel well and under the hood.
A word of caution on the stock grill fasteners, they break easy!!! 3 out of the 4 broke the first time I removed the grill. Since I didn't have any stock replacements on hand, I used some 25/64 Christmas tree retainers instead. Honestly I think they work better than the stock junk.
So, total approximate cost:
Neoprene Air Hose, 3': $15
Air Scoop: $19
3" adapter: $5
3" hole saw: $10
Clamps, screws: $10
So for about $60 total it's a cheap mod by about any standard. I'd swear it helps but without doing some timed runs that's hard to prove. Considering the single snorkel leading into the fender, which is partially blocked anyway, I'd say it's worth the effort.
