What I told you in the previous post was more or less it, but, to my knowledge, this is what you will absolutely need to complete the install and be able to drive your truck again. Note that this is not optimal, or code-free, or any of that, but just to swap the 08+ manifold on and be able to drive your truck.
Bear in mind that I have only swapped this manifold on a WJ, NOT a WK.
You NEED at minimum the following:
08 manifold+ gasket o-rings (150-300 bucks?)
Manifold bolts+ washers (15-20 bucks?)
Air Ram adapters- (300 bucks)
Plug for EGR hole
CAI tube (factory intake will not mount up)
The manifold is capable of being run on a stock tune....but it will not be optimal. WOT AFRs on a stock JTEC PCM like in my '02 WJ were in the low to mid 13's above 4500 rpms. This is on the edge of being safe. From what I have been told about the later style (03+) NGC PCMs, they are much less resilient to modifications so you can likely expect WOT AFR to be excessively lean.
You will have codes for EGR. There may be some sort of workaround to keep the code off without using a tuner.
Ideally, to do it right, you need all of the above, plus:
08-10 EGR (Confirmed to work on Rams, no telling if it works on WKs) (110.00)
SCT Tuner (350?). Diablo is supposedly working on tuning support, no ETA yet.
Wideband AFR. 150-350.00 depending on unit.
With stock cams I had a major flat spot from 2k-3k with the 08 manifold, but that may have been from crap tuning.
