Finished install today, ran into some issues with removing fuel rail for 03 Dakota SLT , ended up being able to disconnect the left side of fuel rail to fit in the new intake, I was unable to disconnect all the right side injectors due to corrosion, the connectors were just disintegrating . Also had to disconnect the metal A/C pipes that sit over top of the intake for removal and installation of the intake manifold. This video was a lifesaver @martinbuilt thank you! Snapped my cruise control cable and my vacuum hose from the intake but she running good now!

[@AIR_RAM_PERF]

Great video Martin, This is the most detailed instruction videos of installing the 2008 intake on the 99-07 4.7L vehicles I have EVER seen! You shed a lot of light on one area most people have issues with and that's swapping over the hardware from the older intake to the 08 intake. I like your 3/4 pipe plug idea however I'm just concerned a back fire could pop it out causing an un-commanded/uncontrolled WOT situation.

[@martinbuilt]

wwwAIRRAMcom Thank you... No I don't think there's any concern with that plug coming out it fits in their extremely tight. If there's any backfire issue it's going to come right out through the throttle body.

[@martinbuilt]

[@martinbuilt]

@Dino Piccinin Dino sounds like you enjoy doing the mods on your 4.7 as well. I am also looking for a set of 08 camshafts. Did you do any mods to the cylinder heads like changing out the valve springs or anything like that. Yes I was going to go with either flying Ryan or airram.Com to get a tune.

[@martinbuilt]

@Dino Piccinin Nice to hear from people that have done the 08 cams and have successfully ran it for a long-time with the stock non HO Springs. Thinking about sending a set of HO cams to Crane Cams they're the only ones that have responded and said that they would regrind them. Maybe someday I'll get around installing a set of ported HO cylinder heads. I would like to have HO block as well.

[@martinbuilt]

@Dino Piccinin which ones are you going to lose the low end on the 206 or the 08 cams.. yes so far I found three sets of ho cams. I let a set of 08 cams get away from me because I didn't know about them at the time. I'm keeping my eyes out for them... and yes the specs on the 08 cam are more aggressive than the 206 I believe the 08 cam has a wider angle of lobe Center though

[@adelemartinez8235]

I thank the lord for your video. U am currently stranded in boise Idaho. Some guy came by and pucked up a wrench and started trying go help me take out spark plugs (I was replacing them). Long story short...he dropped the socket info the manifold. Ive tried everything. Magnets...everything. I undid my manifold but the top wont come off. I sat there and stared at it for a long gime and started to cry. In 900 miles from home and dong know a soul here. Single woman....i am a little intimidated. Wish me luck. I am going to do this. I bought new gaskets. What else do you recommend replacing while undone. I alrwadt did the iac and the throttle sensor and cleaned fhw theottle body.

[@martinbuilt]

sorry to hear that, I wish you were closer, I help you out. I would think you should be able to get it with a magnet, you'll need one that has a long wand on it to reach the socket. I doubt that socket would ever get sucks into the cylinders, it would just sit there on the bottom of the plenum.

[@lelandgray8996]

Hi Martin! As always, love your videos and I appreciate you putting them out there for us to use as guides. I wanted to share something though. I'm going through the process of installing an '08 intake manifold on my '01. The idea of lowering the engine down to get the new manifold in place didn't seem very appealing to me, so I was prepared to take the easy way out and cut the cowling just enough to get it to slide into place. Well, I set the manifold in as far as I could so I could see what needed to be cut, and wouldn't you know it, the '08 manifold slid right into place! I had to wiggle it and move it around some, but it went right in! No having to cut anything and I didn't have to lower the engine.

[@martinbuilt]

Thank you Leland , We're you installing this on a Grand Cherokee? And if so it's possible that your motor mounts are in need of replacing and that could possibly give you the additional room you needed. Nevertheless I'm glad you got it in there.

[@brad3139]

@al carr no difference in MPG however you can feel the power gains in the midrange. the injector swap works well too.

[@brad3139]

@al carr swap took about 5 hours. if youre going to upgrade injectors and the intake i recommend doing them both at the same time since you have to remove the fuel rail anyhow. the upgraded injectors are the Denso 12582704. you can find reman ones on ebay for about $100 for 8. as for the throttle body, the newer 2008+ intakes used a different throttle body which requires an adapter. the adapter cost me $175. ill send you a link to the guy on Ebay who makes them : www.ebay.com/itm/1999-2007-Dodge-4-7-2008-and-up-Intake-Manifold-Adapter-plates/303142636356?hash=item4694b58b44:g:ltQAAOSwOh5cfXOs

[@hestonross4382]

To avoid waisting gas and cautions you can remove the fuel pump relay and turn your key off and on 2-3 times and it will remove the pressure from your rail so you don’t have to do the step you mentioned. Test it out and thank me later. 👍🏼

Yeah man! Thanks again for the heads up on the difference in manifold height, I'm of the same mind. I'd rather not cut my cowling or make any modifications at all other than the intended job at hand. Would it be easier to remove the motor mounts entirely with the four bolts rather than trying to massage them out of the rubber? Ive got a manifold coming. Again thanks for being a trail blazer. On the shoulders of Giants

[@martinbuilt]

Thank you, James. You are very welcome. Just so everybody understands You only need to remove the 2 motor mount bolts to lower the engine enough to get the intake manifold installed. Once the intake is installed the engine can be raised back up and the motor mount bolts returned.

[@jamesdewer]

@@martinbuilt Hello Martinbuilt, I've never had to pull the mounts , yet. Presumably the single bolt hole through the mount has a steel sleeve. I'd hate to be under there and try banging a bolt through solid rubber. A steel sleeve is hopefully inset for steel on steel. I might add the sound of your 4.7 is most auspicious and envy inducing. I'd further like to add this video alone is responsible for the spike and absence of available 2008 WK intakes.

[@josephmorris7866]

You are a awesome mechanic I recently bought a 2005 jeep grand Cherokee limited edition trail boss I payed 700.00 for it because it's overheating and they thought the rings were gone but I pulled the intake and the seals on the driver side were pressed in a lot more isn't that a sign that they tightened it to tight on one side

[@bandaryk]

Hello Mr Martin I just seen Your episode I have my Jeep 2004 4.7 v8 and am trying to install the same thing on my Jeep but I have missing the correct part or way to connect the pip of intake directly from the throttle body to the air box or without air box maybe. And where is the pic sensors installation? Could you please help me how to do that ?

[@brandonsasser360]

I did this swap to my truck recently, but since then, my truck only revs to about 4k rpm and bounces like it's hitting a rev limiter, won't shift when it happens either until I let off the throttle. Any tips or advice would be really appreciated, hoping to have the rest of my rev range back if possible.

[@curtisbradley7574]

Again excellent work! When I did my manifold swap for the PCV, I grabbed a steel brake line with a bore about the same as the factory rubber. I ran it back and under the manifold. It exits under the A/C compressor and wraps around to the PCV. It just made for a cleaner install.

[@martinbuilt]

curtis bradley I like that! I'll have to do that when I pulled the manifold off again to do a wire tuck on the right side valve cover

[@TYVIDIPS]

Would I have to program the compressor again if I remove it ?

[@gregcorley4809]

Excellent! I found an intake manifold from pull it yard on a 2008 4.7 cherokee and plan to install on my 2006 4.7 commander. when I got it home, I found small pieces of metal inside the manifold and I think I have them all out. Question: Can I submerge the manifold in water and flush it out to make sure there are no leaks and to get any additional junk out that might still be there? Pro's or Con's?

[@martinbuilt]

I flushed mine before I installed it with Purple Power but that was to remove any carbon and oil deposits. Sounds like the engine you got that from had a valve seat drop. That will cause the metal to go to all the cylinders through the intake manifold. If you have an inspection scope I would look inside the intake and make sure no metal particles are lodged into the plastic.

Hey Martin, been following for a few years now. Great work! I have a 00 4.7, need to replace the intake manifold due to a broken MAP attachment point. I’d like to swap it from an 02 HO however, WJJEEPS says the Cam shafts would need to be replaced together with the intake. That you cannot replace one without the other. Is this true? Am I better off to just grabbing the intake from a non HO? I’d like to not do camshafts is possible. Thank you!

[@martinbuilt]

That is the first I've ever heard of that. Now for optimum performance you may want to run the ho cams with that intake. But I don't believe it is going to hurt you to run the ho intake without the cams. Thank you for watching and subscribing all these years.

Beautiful work! Lowering the engine by a half an inch reduces your center of gravity. Minimizing your rollover risk. Just saying there's additional benefits

Thank you. The engine only lowered temporarily to get the intake manifold installed and then raised back up and bolted to the motor mounts.

So you only need to lower the engine temporarily to get the new intake in, and once that's done you can reinstall the factory motor mounts? You don't need new mounts that let it sit permanently lower?

yes just lower temporarily and depending on the condition of the motor mounts you may not have to lower the engine at all. I had recently replaced the mounts which held the engine higher.

Hey martin .. I just got done installing 08 + intake on my 04 overland... after seeing what you went through I was prepared to lower the engine but mine actually went in with no resistance... all I did was remove the weather Stripping and I got it in.. the intake I installed was Part # 53032761A1 and donor vehicle was a 2009 ram 1500.. maby the later ones were a little bigger? I have no clue.. but I did have a 1 problem and anybody in stalling 08+ intake on 4.7 H.O will have the same.. bank 2 knock sensor hits the bottom of intake and will prevent proper alignment of the intake.. so mine are now relocated to the outside of the block.. It's still like to know why mine dropped in and yours didn't...

[@martinbuilt]

It could be that your motor mounts are warm enough this causes the engine to set just low enough to get the intake manifold in. I had recently replaced my motor mounts and I think that is what the difference is. I did install the newer 08 intake manifold and I do have knock sensors and had no problem installing it. The runners do look different on the bottom side from the earlier to later model intake manifolds. Thank you for the heads up.

Yeah that could be a vacuum leak but it could also be as simple as a vacuum hose to the brake booster or even a bad idle air control valve.

Yes I installed this intake before I ever did the 08 camshafts. I was running the HO Cam shafts at the time.

[@badillo280]

Would I also need to lower motor mounts on a 04 ram?

[@martinbuilt]

I really doubt that. Just so everyone understands I only lowered the engine to get the manifold into place because of the cowl and then raised the engine back into place.

I’m going to be picking up my intake soon and I’m making my own throttle body adapter.do you think there will still be a pretty good gain with a factory throttle body on the 08+ intakes? Im doing the cams and injectors soon to pair with the intake.

[@martinbuilt]

yes, you will notice a definite improvement. Good luck with your build.😎👍

Rebuilding my motor right now and planning on doing this as well as the HO upgrade...my question is this...do I have to use the plastic like PVC hoses? What if I use rubber hose? Will that cause any issues?

[@martinbuilt]

I think you'll be just fine using a rubber hose as long as it's oil resistant.

[@Kolonol1]

Well after trying for over a year to find a 2008/09 4.7 I finally came across one today...got the manifold...but the cams were fried

Can i use the bolts for the 08 intake from the junkyard on my 03 Durango

[@martinbuilt]

No you can't the bolts that hold down the intake on the 08 manifold are integrated into the coils. You'll need 8 of the older bolts.

Fantastic video! In my case I have an egr valve on my 05 Ram. Therefore you will also need an 08 egr valve and tube. To make intake manifold work. As for map sensor I just bent fuel rail slightly. But your ideas for sensor is just as good if not better. I love my intake and 70mm tb. Get her tuned and you will be amazed!

Hi Martin I have a 2000 Jeep Grand Cherokee 4.7 , can you please tell me what parts off of a 2002 WJ 4.7 L high output I Should look out for at LKQ auto salvage?

[@martinbuilt]

The intake manifold is good but not as good as the 08, the camshafts, maybe the cylinder heads if your up to that and if you are building a performance engine I like the steel crankshaft.

[@Azlivin303]

In the middle of install but my coolant lines run over top my intake manifold :/

[@martinbuilt]

So I take it this is interfering with the install. Is the 08 intake taller in that area to where it interferes? If so can you replace that with a rubber coolant line?

[@Azlivin303]

My question is, why? Whats the point of this? Im curious. Finally getting a 2nd WJ and will try to do mods for more power from the 4.7. My last 1 was also 4.7 but left it stock. Hoping there is a big bore kit, or other non power adder upgrades. Great video.

[@martinbuilt]

Well I can tell you after adding this 08 intake with the throttle body was the largest improvement in horsepower and torque out of any mod I've done so far. I gained a lot from 3200 RPM and up with maybe a slight decrease in the bottom end.

[@ctdope]

@@martinbuilt Oh ok, cool. I was looking on some forums. 1 guy put a list of parts to put in the 4.7 to get a little over 300 hp to the wheels. Thats an improvement over stock. But I dont have any experience with that yet. When I get this Jeep, I have to focus on checking everything to be running right, before mods, but I really hope to be able to play with it. I will be checking out all your vids really soon. Have you denied your Jeep to get the power numbers yet? Looks great.

About how much hp do you expect from this swap

[@martinbuilt]

When I did the Swap and took it out for the first test drive I was absolutely amazed in the gains I felt, even more so then when I installed the HO camshafts. Of course this was with the 75 mm throttle body as well. If I had to guess I would say 20 to 25 horsepower.

[@zacharystevens8527]

What did you do with the egr then if you didn’t connect the house back up?

[@martinbuilt]

My 04 JGC didn't have an EGR. You should be able to run the EGR to the large fitting on the side of the intake, the one that I plug.

[@robgoffroad]

Is this manifold better flowing than the 4.7L HO manifold? I know it's different than the regular 4.7L manifold.

[@martinbuilt]

Yes it does have better flow and shorter Runners than the ho intake manifold. I noticed a huge improvement over my 04 intake manifold

[@nate4036]

Martin, I meant to ask, this is kinda backwards, but seeing the 08 intake fits older heads, I’m assuming that a 04 HO intake would fit a set of 08 heads. I guess what I’d like to know is, possible 08 engine in 04 WJ running on factory pcm, or even a 08 head/cam swap in the same jeep? I’m street car kinda guy and would love to get the power the 08+ Jeeps had

[@martinbuilt]

Yes, a HO intake would fit on a 08+ 4.7 engine. And yes you could install 08+ heads and cams on an older 4.7 The 08 heads have larger intake and exhaust runners with the same valve size as the older 4.7 The 08+ heads do have a larger combustion chamber than the older 4.7 So you would lose some compression but increase the airflow with the larger runners. Check out this video where I cc the heads of an 08 head and an HO head. kzbin.info/www/bejne/eJ2bpKeMaruBrLM

[@nate4036]

@@martinbuilt would you think that 300ish Hp is obtainable with a head/cam swap or probably need a domed piston to regain some compression if not a lil more than oem compression

I have a 2002 Overland 4.7L HO. What spark plugs would you recommend? I have the Champions in it now. Also would a 185-190 T-stat help? I read that the engine runs better cool. I'm not overheating, but I sure do have HOT heat....!

[@martinbuilt]

Yes for the HO engine I would run the champion platinums or I hear a lot of good stuff about the NGK. Yes the engine definitely runs better at cooler Temps. I currently run a 180 thermostat but the radiator is not efficient enough to keep the engine out 180. You have the hydraulic fan the same as I do I am personally not that crazy about that fan. In theory it should be great but I feel the RPM is a little on the slow side. I did figure a way how to pump up the RPM but I also noticed that gas mileage suffered. So I am currently working on a electric fan conversion. I don't want to do the full install on the fan yet since we do have cool temperatures I want to wait till things warm up a bit so I can see the actual difference.

So you only have to lower the motor on a grand cherokee? Ive got an 02 durango i wanna do this too.

[@martinbuilt]

yes, depending on the condition of the motor mounts. With old worn motor mounts the intake will go in without having to lower the engine to install the intake.

[@jasonlowery1591]

I’m following your videos and this upgrade in particular I’ve been hearing about for years from Dakota drivers. I have a 2002 Dakota QC 4x4 with the 4.7engine. So I got an 08 intake from a Chrysler Aspen 4.7 and am in the process of cleaning it and fitting it. One issue arose that you touched on, but was confusing. The intake from the 08 Aspen didn’t come with the 8 double ended intake stud sleeves. Those 8 steel sleeves that get pounded into the perimeter of the intake to guide the studs down to bolt down the intake had to come from my stock intake. But your right. They don’t fit, except for 2 (1smaller one and 1 flat sided). An option is to drill out the other holes with a 1/2” bit ( IIRC LOL) and wobble the bit some to fatten it up on both ends. THEN, the sleeves will push down into the plastic most of the way and you can tap them in and reuse all your studs. One other thing is the PCV (NOT PVC LOL) set up. My intake came with a short PCV hose that connects to the intake and what looks like the same PCV you threaded into the drivers side head. So I’m getting that PCV (if UPS will stop losing it and deliver it) from your amazon link. So that’s a short run to that side of the engine. What about the other side? Can I just put a cone filter on the passenger side 5/8” pcv inlet? Or do I need to reuse some of the old tubing to run that passenger side pcv inlet to my double coned filter eBay intake? Does this passenger side even need vacuum also? BTW I’m going to be getting a oil fill hose WITHOUT the pcv valve in it and replace my stock one like you did that has it.

I have a quick question. I am grateful for your channel. I have a Jeep so, I look forward to upgrading like you do. I over torqued the manifold intake bolt towards the front (right hand side, closes to the head light) and snapped the bolt in the head. Now, I took out the manifold intake to put in a new bolt in it's place but can't figure out how to get it off from the actual manifold, and is it possible without having to getting a new manifold?

Yes you should be able to drive that bolt out from the underside of the intake. Use a small deep socket and a hammer. Shouldn't take much effort.
