 Subject: 4.7 HO Intake; lets get it straight.
IP: Logged
Message:
Ok...I'm gonna purchase the HO intake from a Jeep (online price $180) and want some straight info from people who have swapped this before. Yes, I have searched and there is too much info to look through.
If I order 53031739AD which is the listed PN for an '02 Jeep 4.7 H0, does this include all gaskets (I thought I read that it is all o-rings and such). Normal hand tools or anything special? Tips, tricks or other ideas gathered from your install?
Now, I've decided on the intake because I can't stand how my 4.7 falls on its butt before it shifts @52-5300. I wish I had a stick but I bought used and this fit all my other wants.
I read plenty of opinion on this part through the search, but any more is more than welcome.
Thanks...

No special tools needed and no gaskets needed. Yes it does come with o-rings. Leave the TB on the old intake, when you get it off it easier to switch the TB from the old to the new with the intakes off the truck. When putting the new intake on, be sure to connect the vaccumm (sp) hose up first before setting manifold in place. You will have to loosen the fuel rail in order for the MAP sensor to clear on removal and install.
Thats about all I can think of, hope this helps ya,
Later...

Do you have the HO cams? Because the intake is designed to work with the cams so, I doubt you'll see a huge difference in top end. What year is your engine? If you can get to them, I'd unbolt the dipstick tubes and move them out of the way or you'll be cussing at them the whole time like I was. Those damn things are in the way constantly during the removal and replacement process. I installed the '04 style intake on my 2000 and there wasn't a huge improvement but it runs smoother at higher rpm than the stock. But I would recommend getting a FastmanŽ throttlebody and a good CAI before going to the manifold. The intake manifold change tends to be a lot of work for what little gain you get, whereas the throttlebody and CAI are relatively easy and you probably get better gains. Remember, the air has to flow through those two items before it get to your manifold so, if they're substandard how can your manifold improve much? Do your homework on the manifolds too, if you have an earlier engine you're going to run into PCV and vacuum line problems to solve as well as the IAT sensor will have to be replaced because the early engines used a screw-in sensor and the newer manifolds used a twist-lock sensor.

I haven't read on that link yet (getting there) but I thought the Jeep's HO was different than even the newer style 4.7 intake. Mine is an 02, not sure off hand if I have a screw-in sensor or not.
I'm not looking for peak power increases, just to drag the power a little higher so it doesn't drop off at ~4800 before the auto shifts.

Ok, you seem to know what you're talking about with these manifolds so...
Is there any literature somewhere that would tell me the differences between the 02 HO intake (I got the PN cross referenced for an 02 Jeep, matches your link) and the re-designed 03+ intake?
I'll assume the the '02 HO intake will be a more direct bolt on to my '02 4.7, meaning no sensor changes or anything along those lines. Is that correct or am I making an ass-u-me?

Since your engine is an '02 4.7, you won't have to worry about the IAT, PCV or vacuum lines.
I don't know of a site that documents the specific differences between the 02 and the 03+ HO manifolds. However, since DMC decided to change the design of the HO manifold and use it on both standard and HO engines, there must have been a good reason and I don't think that reason was because the 02 HO manifold just made too much power.
It sounds like you're pretty well convinced that the 02 HO manifold is the answer to your dreams. I just hope you aren't disappointed after you spend all that time changing out the manifold.
Maybe someone that's done just the manifold will chime in?

Well, I think I'll compare costs if both will work with all my existing sensors etc.
We'll see...

Ok, the 02 HO manifold can be had for $180 online. The '04 manifold can be had for $70 at the same place.
Is this cost difference purely due to differences in production numbers or what?
I wish things were cut and dry because I wanted to clear up all the hooplah I read when I searched this topic. SO...
One last question: When did the sensor changes take place? (Cause I might just take the $110 discount if the 04 manifold works snag-free on my 02)
Again, THANK YOU for dealing with my indecisiveness!

I stayed with the 02 HO intake because my truck is an 02 model, and I wanted to make sure I would not have to worry about something not fitting exactly right or something doesn't line up...
The 02 models have a twist-n-lock IAT that goes in the intake manifold. I think the newer 04 models the IAT mounted in the intake tube between the TB and the Air box.
I agree with RobC, you might want to get the TB, and a CAI first. A lot of people would put in the cams and HO intake at the same time because the intake will cause you to lose some low end torque, but the cams would make up for that.
Hope this helps you...

Actually the IAT sensor didn't get mounted in the Airhat until the 05 model year. I think the twist-in sensor came out in 2001.
The only thing that you may have to buy if you go with the 04 manifold is the PCV tube assembly that plugs into the back of the manifold. The 03+ style used a tube with a different angle and location. I think I paid the local Jeep dealer less than $10 for mine. You could probably get the place that sells you the manifold to give you a discount on that part.
If you go to the link that I provided you can see the two manifolds side-by-side, I see some differences in manufacturing that may have saved some money but, I'm guessing it's mostly because people are paying the higher cost of the 02 HO manifold and DCM doesn't see any reason to lower the price.

I have a '01 RC 4.7 5-speed. I have the Jeep HO cams, but kept my stock '01 intake manifold to keep the NICE low rpm torque curve compared the HO manifold. Sure, it flattens out slightly above 5000 rpm, but there is so much useable torque, I just shift to the next gear and keep pulling. TB mod/air intake/Y-pipe/hi-flow cat/Flow70/duals also compound the effect.

I Run 33s swampers on my durango and do mild to heavy off roading I really dont need the speed but more torque. So would I be better off with the HO cams or the 206 cams, HO intake or the stock intake?
I will also be running a fastman T/B I have a cold air intake now and superchips programmer set on performance I hav'nt touched the exhaust yet but I see headers and cat back coming.

Mud, you're probably better off without the intake since you are lugging around the weight of that Dingo and MT tires. I can't speak for the 206 cams as far as what they do in performance, but the Jeep HO cams (KRC's 200's) definetly pick up the torque.
Skip the headers also, little to no gain with those on a 4.7. Stock manifolds flow very well. Spend that money on the y-pipe, it sucks.
01Motorsport - I wish I had the option of short shifting a little bit, but the auto just won't do it when I bury the pedal. Really wish I could have found a 5spd with the other options I was looking for.

I've got a 01, 4.7, 5spd manual, yadda, yadda...
Did the HO cams first, then months later went to the HO manifold. I didn't dyno that change, but I really couldn't tell the difference in low torque. I'm considering putting the 01 non ho back on and re-dyno ing and see if there is a difference and where. I've got a dyno of the current set up.
I remember the PCV being somewhat different, and having to use the original two screws for one of the sensors up front. I think i remember using a piece of rubber tubing I had around to let the PCV hook up right.
