- I finally installed an Air Gap Intake Manifold and Big Gulp Throttle Body. The Top-end and Mid-range of the power band have improved dramatically. I am very happy with this purchase.
List of Mods:

Mopar Timing Set
Mopar Valve Springs with .600" shims
Mopar Lifters
Intake
Hughes Engines/Edlebrock Air Gap Intake

K&N Cold Air Intake with IAT sensor installed on it (Air Gap doesn't have a spot for it which you're told :D)
K&N Air Filter
Exhaust
Stock Headers
2.5" Stainless Steel Piping Welded to the headers leading into...
Magnaflow 2.5" Stainless Steel True Core X-Pipe leading into...

Stock Transmission (180,676 miles and still fine!)
242 T-case (Selec-Trac) out of a 97 GC
Then you've come to the Perfect Shop! We specialize in Mitsubishi and we're deep into the Mopar Industry
That jeep looks like it's a pita to work on. My ram 5.2 has so much room it's crazy. Nice jeep
It is
The dakotas got both of yall beat. I just pulled a hughes off a ram. It's a pita because of the cowl.
Haha I did the opposite when I hooked up my new computer. I immediately ripped a burn out out of the parking lot so it could calibrate WOT. Your Jeep sounds so good! My plenum has blown for the third time so I’m looking to order the airgap for my 5.9. Your right about the sound of the intake. My 5.9 sounds like that with the cold air intake. I can’t wait for the upgrades.
Love Mopars and Mitsubishis!
I hot rodded a 2.6 Mitsubishi in the early 90s
5.2 . Zj 😍 love the work you put into this thing man 👍
MOPAR Means >>>Massively Over Power And Respected
Thanks! Yes and just get a custom tune from an sct dealer if you go with the cam. with just the K&N and Exhaust you'll be good to go because the computer can learn around that.
Hey, my mpgs have actually improved decently. I was averaging a mere 11.8 mpg (85% city 15% hwy driving) and now with a transmission that's on it's way out I'm averaging about 14.1 mpg with the same exact driving habits. I think fixing my transmission should put me in a 15-16 mpg mark hopefully. I have gotten as much as 19.7 hwy (that's great for a 17 hwy sticker statement)
Thanks for the response. I know there's not a lot that can be done to the 5.9 to get much more mileage, but I'd like to squeeze a couple more out at some point. mid grade fuel is the lowest I can run so every bit helps!
I don't plan on it, but I might later down the road. The stock computer can take up to 500 miles to fully recalibrate its parameters. I've driven 45 miles now and it's improving every drive =)
$4.59 a gallon, keep voting for the same politicians, get the same results. It’s so sad what happened to Cali, coming to the rest of the US! Do not vote for the same system that give us the end of California Dreaming...
PS the intake sounds nice, love the “4 Barrel” sound!
dude, I am stealing your exact setup.. I love the sound, and the gains look highly noticeable. Do you have any updated videos? Possibly at WOT? I'd love to see how it responds.
Well not that I don't like AMC (they did great) but Mopar did a great decision by throwing a good old 318 under our hood, and an even better decision in 98 when they threw the 360 under the 5.9 limited. I love my ZJ and I'll keep it til it dies. What I really want is a TJ with a 5.9 Magnum swap with 5 or 6 speed manual!
Just did my 98 ZJ 5.9 with an ax15 swap. Went with toyota internals to beef it up a bit.
I put my IAT in my airbox too. Relocated coil to the firewall. Has a much shorter wire now. Less resistance.
Killer job man. I'm looking to do similar upgrades. Now I know what to aim for. Thanks for the video.
The driving sound reminds me of a 6.1 srt8 hemi with magnaflow exhaust
i installed a 360 magnum with a Hughes 208/214 cam in my 79 dodge. carbed at the moment but I'm going efi after i do the exhaust. definitely going to this manifold. thanks for the video, nice jeep.
Iac idle air controll valve. iat intake air temperature sensor two different parts I believe.
No Problem. Happy Mods!
Dam I wish d&g motors was still up n running. I need a shop for my 5.2 Jeep mods. 😞
Im new to the jeep line after mopar got them but im learning all i can.Ive had a 79 wagoneer amc 360 and quradratrack and i loved it.I still have a CJ-5 304 the body is rusted away with 94k miles but runs like new.And just got a 97 Orvis with under 85k miles.Its looks new and runs strong with the 5.2 but i want to make it stronger.Just not sure what works on it till the comp pukes out.But i do know the 318 is a great motor from back in the day.
Sounds sweet!
yes, but with lockers just be careful on turns because the truck will wheel hop if turned too abruptly. The reason vehicles come with open diffs or limited slip (but still some slip) is to avoid this hopping on turns. On a turn the wheel on the inside spins slightly slower than the outside wheel. without a means of some slippage, the diff can get damaged. Just Be Careful on turns!
Just as an update (10-7-12) I have now driven over 1500 miles and the computer has definitely learned the intake and throttle body well The truck pulls hard all the way to red-line. I want to put it on a dyno and run 2 or 3 pulls so I can gie everyone actual numbers instead of guesses. It has to be making close to 300 hp at the motor and 350+ tq
The point of having the IAT in the intake manifold is due to the heated intake will raise the IAT temps.... that being said ive done the same thing, but not hooking up the breather to the intake tube is silly
But is it worth double the price over the edlebrock air gap? Because the huges ones is made by them. And they both look basically identical
At first I was like wow that was a waste on that 5.2, watching the pull on the freeway I was like ummm that speedo didnt move very fast, then you said it was half throttle. I was like ok that explains it. Cuase I built a 360 with that hughes air gap and I'm running 35s and I did a 7.5 second pull 0-6 in my truck and my speedo flys! I got my truck doing 110......to fast for a truck with 35s lol
but very cool build!
Quadra-trac is good but I swapped mine out for Selec-Trac because I like having a true 2wd mode and still have a full-time 4wd mode. Quadra-Trac is "2wd" until the rear wheels slip causing the infamous Viscous Coupler to heat up which transfers power to the front wheels. Hence it's a full-time 4wd system. The Viscous Coupler is known to fail every 50-75 thousand miles (mine failed every 45k). Selec-Trac doesn't have one so it doesn't have that problem. It also won't bind on turns like quadratrac
I have read that with a stock engine this manifold offers no positives?? is this true? What upgrades have you done? My plan is to put the manifold on 97 Dakota 5.2L. I have K&N intake, magnaflow cat and exhaust (no duals). Would you recommend?
Jarrod Padilla Definitely false, although gains will be very minimal. You're increasing flow in the middle, basically, but without CAI and a free flowing exhaust, you're still not really helping. gives you more top end, but you need those other two at the very least, and then DEFINITELY want an SCT or custom tune to pull it all together, otherwise the computer tries to compensate for the flow to stay as close to stock as it can.
Mine had CAI and headers+ full exhaust without much of any noticeable gain except sound... then about 2 months ago put an SCT 91 octane tune on it and BAM, 0-60 dropped almost 2 whole seconds! Your stock computer tune will really hold you back. Definitely get a tune when you add this and you will not be disappointed!
Thanks and Good Luck!
Can't wait to get one for my Dakota rt
right on
Who disliked this?? Someone driving a honda lol
Snowflakes in a EV
I'll tell you right now. It totally is!
Did you have to get a turner when you out this intake on? I’m worried this will mess with the fuel air ratio.
The more research i do the more i like whats been done and i would love to have a 5.9.I want a set of headers but only 1 maker for them.I like the quadradrack what do you think.
Just did full suspension and truss on my 98 5.9 ZJ and i decided to keep the stock Nv249 transfer. Just opened it up and went through it and deep cleaned it and painted. Swapped out the 46RE with an ax15 with toyota internals. Gonna go with 4.10 axle gears for now since i already have the front gear set and lunchbox locker in rear with the gear upgrade. On 35" BFG KO2 right now but im considering some 37" rubbers
Weird question for you. Does it sit higher, or lower than the factory keg intake? Clearance is an issue on ZJ's.
Mileage might increase slightly, but I'm not sure on power. Low end torque will definitely decrease I don't think too significantly because of the stock exhaust. If you can get an SCT tuner. That with the manifold will wake things up greatly and u the mileage 1-2 mpg
DGmotors NYS wanting to get more power out of my 5.2 mag would the bigger intake help orrr?
Moving that temp air sensor closer to the air filter helps i do that on my gm tbi n it really pulls nice but my mpg drops big time
How do you get the green gauge color?
I allso have a 85 M-1028 that came with lockers in both front and rear with 4:56 gears.It pulls anything i hook it to.It has less than 38 k miles.
Put soon I'll get a cam and rhs Indy x heads which are sold by Hugh's engines. But damn Louisiana 91 octan is 2$ a gallon fell sorry for you
1:09 you mention that the Stock Computer has not fully learned the Throttle Body and Manifold.
Are you going to have it dyno tuned?
Why does your tac go up to 7K rpm? My 5.2L only goes to 6K rpm, and it doesn't even need to go to 5K tho bc max HP is at 4400 rpm.
Moneyhungry, What did this set of mods do to your mpg?
I'm running the stock 98 5.9 and I love it, but I think some upgrades will be coming in the not too distant future...
So you cammed in with a 100 percent stock pcm? No flashing?
It has a BG Performance flashed PCM with specs to my build. I run 93 Octane
I'm sure you're still happy with it but my engine is bone stock. I thought I'd buy this manifold because I have a plenum gasket issue and was wondering if it would be worth it to get the intake instead of the reinforcement pan...
Would it be negative for me in any way (mileage, power) if I installed the airgap intake without any other mods on a stock engine?
Thanks for responding!!!
Dude that things awesome. Got a question bout the t case swap. Did you have to swap input shafts from the 249 to the 242. I have a 95 5.2 zj. And want to do the 242 swap. But am just wondering if there's a 242 with the same input shaft as mine. Pretty sure mine has the longer of the three shafts. 1.55.
Yes you can without having to swap. just find a t-case from a 93-95 ZJ and you should be good. (96-98 can be made to work but requires more work)
Any tips to installing? Just wondering about the iat sensor. Did u use all the kit it came with?
and how did you thread the iat into the k & n tube?
I've heard this intake setup on a 5.9 is worth an honest 50 hp & 25-35 tq. =D I love the way this intake setup has also changed the exhaust note and makes the intake sound like a giant vacuum
The rear has a locker and im adding a front locker so that would make it a true 4x4 right.
So did you see increase in hp?
We have the original Evo X MR making 500 hp in for an annual check up
There’s 318 Magnum V8 engines are affordable and plenty of parts available for the 318 and 360 Magnum engines
3.73s from the factory. Ive thought about 4.10s though and a lsd from a 5.9 zj would be awesome
I wanna do this just need the money but I sure am glad I dont have any ac lines in the way lol
Great car man!!! Could I get more power and good performance using a K&N and Magnaflow 2.5? What I need to do in my ECU if I put a good cam as U r using in your GC?
Old video, I know...but do you happen to know where I could get a Mopar Performance ECU for a '97 ZJ 5.2? I saw you had one (a few years ago).
Old comment, I know.. but I'd add yourself to the ZJ Grand Cherokee Owners Group on Facebook. We're 15k members strong, there's bound to be a few people that have one they'll give up, at a decent price too. And as long as you aren't Mr. Obvious or Mr. Troll on every post, we always love getting new members and rigs in, be it lifted, lowered, stock, built, swapped, chopped.. don't matter, we don't judge. Lol
Hit up kolak hes the man kolak@aol.com
=D gotta love it!
what brand HiD bulbs are you using?
MSD 8.5" Super Conductor Wires link ? plz
What gears are you running i have 3:73 gears and a factory posi in my 97.Love the vid
did the blaster coil make any hp? thanks
hey beautiful rig, question on your cam. did the stock pcm continue to run it just fine? I'm considering the cam but I'm 94 obd1 so I'm stuck with stocker or the Mopar pcm. did it go into fail safe or did it run fine?
On the Brink Outdoors get a custom tune and you're good.
Carb swap it and you won't have to worry bout all that computer bs
I love the sound of that engine. I've been wanting that intake, but I imagine all the mods you did work nicely together. I read somewhere that 95+% of all 5.2 & 5.9 stock heads are cracked have you replaced yours or had any issues??
Jason Davis . 2000 dollars?are you smoking meth?you obviously have no clue what you are talking about.
Those heads are are 350 each.how is that 2000? I know what I'm talking about. Over 15 years of experience 10 years at the dodge dealer and the other 5 has been building race engines.so I know what I'm talking about.you not so much
350 for iron ram heads with ss valves.and you cant forge cast iron.so stay in your over priced world
It's actually called a blast furnace not a forge.
Shut up kid do research before you try to argue with a grown man.
How does it idle im running same setup but 95 zj
im just gona put a heavy cam, carb swap and an edelbrock manifold on it. probly headers and maybe better pushrods and rockers
If you go high lift short duration, you better be doing valves and springs too, because you'll either snap a spring, obliterate the ends of any pushrods you install, or marry a valve to a piston. And why on earth would you carb swap from a MPI, electronically controlled trans system? You do know the PCM relies on the TPS, MAP sensor and IAT sensor to help set a lot of functions, like ignition timing, shift points and line pressure, overdrive and converter lockup.. etc, and if you remove those things (you wouldn't be able to run any of them on a carb and carb intake), you're just going to end up dumping a ton of money into making your OBDII Mopar run correctly, and make less power and be less efficient all at the same time! Oh, and good luck finding a fuel pump that will fit into the sending unit that won't blow out every seal on that carb as well.
What intake manifold is this?
what computer did you used to have?
minha e uma v8 ano 1996...bate partida e nao pega .....troquei copo,,martelete rotor ,,testei sensor de rotacao de fazes...aagora nao vem corrente na bobina
What cam you running
Lol well we've had Canadians come down with their Evos so... yea ;D
so what would need go get the intake at and stuff
dumb question but are all 5.2 in jeeps a magnum cuz I been needing some parts for mine and some parts say magnum and some parts don't, and if their all not magnums are the parts compatible
Yep they're all magnums
just make sure you get the appropriate parts for your motor year, there are some minor differences between certain years
Do you still have this jeep?
Whats your mpg now? lol just curious
I'd like to thank my mom for birthing me to own this truck.....😂
Nice cherokee ,,,,,, 👍👍👍👍
Do you have any 0-60 times with the intake?
nothing on video officially cause my 0-60 video was with not so good shifting
hey what did u pay for the hughs system did u have to tune the computer thanks rob
Rob bigemon you don't HAVE to, but your computer will do it's best to compensate for the manifold and keep you nearly close to stock power. all you'll really get is low throttle improvement/mpg and cooler sound. Until you actually get a tune (or SCT programmer with the tunes on it), you won't be getting nearly the gains. I just added a tune 2 months ago to mine, which has with headers, full exhaust and CAI, which got almost no noticeable power gains at all from them... until I installed the 91 octane tune! BAM!!! 0-60 improved by almost 2 whole seconds, shifts at 5000-5100 rpm instead of 4400rpm. Really pulled it all together!
So no, you don't HAVE to have a tune, but yes, you WANT to have that tune! Also, once you have a better flowing manifold, the tune can be made even slightly more aggressive. I have the more aggressive tune waiting in my email inbox until I get my M1 intake manifold & 53mm throttle body installed, and then I'll really start pickin up some power. Best if you also install either a small "RV" cam or at least 1.7-1.72 ratio rocker arms to provide more valve lift to take advantage of that flow capability, otherwise you might lose a little down low.
JoeIsCrazyWillman Hollywood is that you?
so how many gaskets did you blow before you hooked the pcv back up? lol
+Medicated TV The PCV has never been disconnected
+DGmotors NYS you realise that vacuum line from ur valve cover to the intake is there for a reason right?
+DGmotors NYS im sorry you say you got a cam and shit but my stock 5.9 with msd ignition and full exhaust I would put truck lengths on you
the pvc is hooked up. its on the passenger side.
hey you got a number so I can ask you wuestions about the hughes intake
Where are yall located
I have mopar performance pcm
Where did you get the dash leds from?
superbrightleds . com
what model light bulb did you purchase?
I believe they are 194s check the vehicle bulb finder
I'd love to, but it would be a 1300 mile drive lol
I just ordered my hughes.. Pretty pricey.. $630 hope it's worth it
MrJoehawkin2007 Make sure you get an SCT or custom tune. stock computer will try to compensate and stay as close to stock as possible. It will run without the tune, but will be drastically less of a gain.
MrJoehawkin2007 damn they are 359 right now
You need a tune
Im having a hard time finding intakes for the 5.9 magnum every last one I find says its for carb. I want efi, or is the carb thing just one thing it can be used for. I dont want to convert my 02 ram to carb, at least not right now. What intake is best? I want one that has a good feel of power and goos to start building the stock mopar up into a beast. Any help there is so much I dunno what to choose and Ive got a tight budget right now.
commanderwhite12 The Hughes intake is good, but they run $600 for the kit.
commanderwhite12 There's still Mopar M1 2bbl & M1 4bbl intakes for sale on the web. Not from regular sites, but either eBay sellers, or else on Facebook under a set of closed groups (somebody you're friends with has to add you) there's a guy named Rolf who sells the manifolds, adaptor plates, billet fuel rails, and 52-53mm ported stock throttle bodies. Fantastic work.
M1 2bbl is superior to the Hughes by a little bit, tho out of production so what you'll find will likely be used. The 4bbl is a little better for bigger builds, but still similar gains on lighter builds, and he supplies a 2bbl adaptor plate to use the stock 2bbl throttle body, and then when the time is right for big power, switch to a 4bbl throttle body and simply remove the adaptor plate and bam, more flow for those huge cams, forced induction, or nitrous
Wish I still knew how to get in contact with Rolf. He's gone from the 5.2 and 5.9 performance group, all of the ZJ Grand Cherokee groups, and now I can't find a 2 bbl or 4 bbl M1 anywhere for under $1000, which I refuse to pay for an intake that's going to put down half the gains of what a cam, cheap mid-length headers and a tuner would do for the same price combined. The performance difference is way too marginal to deal with people who act like their M1 is a solid block of gold, when I can order a AirGap for $600 to my front door. Really would prefer an M1 in either variation for my R/T build over the winter though, no doubt.. but for me the price and performance differences aren't worthwhile, and them all being used, you never know what condition it may come to you in. :/
Sweet! Now time to lift the fuck out of it.
Year is 2024 & gas is 5.50 for 87 octane 😆
Did you get better MPG??
@Ricardo Alcaraz people are actually happier with the improved gas mileage over the increased power with the Hughes intake manifold.
@Ricardo Alcaraz *facepalm* just read about it on their website
@Ricardo Alcaraz ima pray for you 🙏 🤦♂️
So you're going to sit here and try to lie and tell everyone you're a mechanic, but call tube headers "straight pipe headers", say a straight pipe exhaust and a fucking CAI will give you more power when in reality, all you're doing is moving the peak of the powerband to the top of the curve, and killing more bottom end torque than you're making top end HP? You can't really be THAT stupid, even if you've never touched a wrench, can you? Yes, with an upgraded intake plenum (leave the fucking air filter alone, it's bringing in more flow and cooler air than your hot air intake ever would), headers and a more free-flowing exhaust you will pick up power AND fuel economy, usually around 15%. Then if you throw a cam, valve springs and rocker arms and a tune at it, you're making a good bit more power, and maybe upwards of 5-6 MPG better economy. The factory TUNING for emissions is what kills the power and oddly enough, also the fuel economy in a vehicle. Not so much a hot air intake, tube headers and a straight pipe. You are right, that's a good way to improve your 0-60 time by one tenth of a second and drop your fuel economy a few miles to the gallon. FOH with your stupid lying ass. Also, you really slapped yourself in the face with that "liberals" comment, because I guarantee the bullshit you're spewing came from another dipshit on the internet. Kinda funny how your condescended and played yourself all in one there lmao.
@Ricardo Alcaraz Does this mean that you imply that you're _NOT_ a "liberal's (lol)? I, sir, am a mechanic. You, sir, are not making a very good case for your claims of being one. Also, please refrain from making an ass of yourself throwing the word "liberal's" (yes, you mispunctuated it as well) when you are in fact the one displaying yourself in a manner consistent with those who actually deserve to have that particular slant thrown at them. I'm sure this comment will trigger you so let it fly, brother, let us have some more laughs!
Cam? headers? An Air Gap thru stock ones doesn't do dog....
"5.2 ZJ Hughes Air Gap Intake & Big Gulp TB Dual Exhaust Cam" seriously? You HAD to have read the title of the video before you clicked on it, which lists that is has an Air Gap, Big Gulp, dual exhaust (true dual, and nobody does that on a ZJ with the major PITA that is without running shorties at least, and I happen to know the owner and yes, it does have mid-length headers) and last, cam. The title literally had the answer to your questions, and I'm just wondering how you missed it entirely.
liar that's full throttle passing gear does not kick in un less its floored yours did
Cam Crysler your full of shit it was fucking to the floor struggling.we all seen it
Not true. My ZJ kicks down with medium throttle. At WOT it kicks down way more than what he showed in the video.
That things a dog lol
Anyone wants a m1 with a custom 53mm throttle body, I know where you can get one for way cheaper than this crap
buddy robinson I am interested in the M1 please let me know
