Thanks man! I was planning to keep this thing stock but that didn't happen. I currently have HO cams, ASP underdrive pulley, 08 intake, ported TB, Superchips programmer, Jeep TCM, 4.10 gears, ceramic coated headers, mangnaflow cats, magnaflow cat back exhaust. Typical "stock" truck LOL...

So I finally got around to firing up the truck after the 08 intake install. I went through the standard start up and let idle (w/o touching gas pedal) until up to normal temp. Then I took it for a spin. I just did some normal driving for the first 10 miles or so. Then I got into the pedal a little. The truck fell on it's face. Knowing it was still "learning" I drove around another 20 miles near normal. It took about 40 miles before it started coming around. After 60 miles It definately pulls harder from idle all the way to 6000 rpms. Low end seems slightly improved but you really feel it above 3000 rpms. I have 4.10 gears so it's hard to do a full throttle take off without tire spin. It definatly makes a seat of the pants difference. To me that's all that matters. I recommend this 08 intake mod!

Okay I need a run down of what you did for the swap. What was in the way, what hoses had to be moved, ect.... Details man!! lol Step by step is what I'm looking for.
First you'll need to buy/make an adapter plate to mount your existing throttle body to your new 2008+ intake manifold (that's a whole other discussion)
The following needs to be removed before the swap:
-intake pipe to air filter
-stock throttle body
-map sensor on front of stock intake mani
-pcv hose, and a few small vac lines connected to the intake mani
-coils
-fuel rail with injectors (a pain)
-any heater hoses that go over the intake mani
-alternator
Then you can unbolt and remove the stock intake manifold.
Install your new 2008+ intake manifold, and torque to specs.
Reinstall everything you removed.
Maybe my install was unique, but I had an interference issue with the front of the fuel rail hitting the map sensor. My errr solution was to mount the map sensor upside down (turned it 180 degrees). Seems to work fine so far.
You will definitely need a custom tune to richen up WOT. Without doing that, the new manifold might give you LESS power because it'll be running so lean! But once you fatten up the mixture, it'll give you a nice bump in power.

For the instake swap I needed the following.
1) adapter plates for 08 intake to older TB
2) Throttle cable brackets (if you have an 01 you can use the stock bracket, if not the air-ram adapters have this)
3) Extention wire for the air intake temp sensor (it must to relocated, on mine I put it in the CAI tube)
4) Vacuum line to extend the PCV valve line (on the 08 intake it is on the drivers side of the intake and on the older intakes it's on the rear)
5) As others have mentioned there is an interferance with the Map sensor and the fuel rail (I just bent the fuel rail cross over slightly)
6) I also placed some pipe insulation arounf the coolant lines which run over top of the intake.
I might have left out a few things but this was the just of it.
Others have stated you need a custom tune to take full advantage of the increased air flow. I have the Superchips tuner set to "towing". I noticed a difference by my butt dyno. I am a little skeptical about spending the cash on a custom tune. I will probably do it in the future but just installing the intake makes a difference. I'm happy with the intake as is.

My JTEC 4.7 with intake/exhaust/TB would run low 11s AFR above 4500 rpms on stock tune.
Wow, that should be fat enough to support (mostly?) the 2008+ intake. On my NGC 4.7 with the 2008+ intake I'd see the A/F ratio go leaner than 14.7 above 4500 rpms!!! I need to get a wideband O2 on there to see what's really going on, even with my SCT tune.
My 2003 Dakota and 2006 Ram with the 4.7 BOTH ran rediculously lean up until catalyst overheat protection kicked in, even bone stock. They ran ~14.7:1 up until 75-90 mph and then the overheat brings it down to 10.5:1 af. They both picked up 2-3 tenths in the 1/8 mile alone by eliminating the WOT Fuel Delay, something Superchips does not do. Even on stock tune just eliminating the WOT fuel delay, with HO Cams or 218 cams, 2008 intake, and Headers the WOT fuel dropped close to where it needed to be around low-mid 12s.
EDIT- Does not necessarily pertain to the 08 intake, but I will say that even a stock cammed 5.7 with long tube headers was fairly happy on Superchips 91 tuning. A/F ratios were held at 14.7:1 across the board with mostly negative fuel trims at part-throttle. Eliminating the WOT delay and starting with a 5.7 based tune in the 4.7 PCM did give a touch more power though.
This was my 5.7 Hemi on Superchips 91 tuning for a 2006 4.7
This was with SCT Tuning and the WOT Fuel delay removed, low 12s across the board AFR, 28* total advance, lots of weight to get moving and no gear. 5,480 + driver and 3.55s turning heavy 32" tall 305/50/R20s

I just installed my 08 intake and I think you guys almost have me talked into a SCT. I was kinda on the fence for $265. That was more that I paid for my TBSS tune and it made a huge difference!! But I didn't get a nifty little machine to go with it either lol!

I need some help guys. I'm installing my 08 intake now on my 01. Is the intake temp sensor the one that is on the drivers side of the 01 intake on the runner? Is that the one that was stated in an earlier post to move it to the cold air intake? Any help will be appreciated.
Thats the one..
