hey there guys just curious but has anyone here tried to do an intake manifold mod of any kind? i was looking at gen coupe IMF an theres are all aluminum and was thinking of trying to grab one an see if i could make it fit but i quickly saw that there upper IMF and lower IMF have a completely different design compared to our NF 3.3s, theres go in an almost 3x3 parallel setup and ours is an inline 1x6 setup...looks kinda similar to a tiburons. so has anyone(im eyeing you mainly on this V!) here got a clue if the lower intake manifold that mates to our block would be swapable (yes i just made that up) with a Gen coupes 3.8 or any other lambda powered vehicle that may have a better intake manifold. this is all high hopes though cause im sure there would be a cel or some other list of issues to deal with that i havent accounted for yet.

I have also looked into this and the spacer thats made for the gencoupes. For starters the manifold on the gen coupe would be facing
the wrong way if attached to the Sonata. The intake inlet would be facing the belts. So anything after market you would have the same issue. Assuming this was not an issue I am pretty sure their would be some kinda issue with the variable intake runners as I am sure the programming for the 2 different cars are different. With that said I am fairly confident the lower intake manifold would bolt to our head. However if the head ports are different (which I doubt) it wont fit. Hope this helps!!

hah dang i completely forgot about the orientation of the 3.8. i was just thinking hey grab one upper and lower IM rotate em 90 degrees counter clockwise and bolt right on hah since the manifold itself would technically face in the right direction that way ahh so much for being optimistic lol, maybe tomorrow ill visit the salvage yard...they just got in a 3.3 NF if it isnt damaged ill snatch the IM off of it and see about porting the plastic lol.
here is option 2. the new Azera is a detuned version of the gencoupe..... That manifold might work?
ah yea thats right and that would be a more likely bolt in fit but still id make sure to grab both upper and lower IM just to be on the safe side. heh ah today was a bust at the salvage yard they didnt want to let me pull the parts off the motor cause theyre trying to sell it complete....only had like 50k on it. although i did grab that fender well that i lost =)
Hey V so i was bored and was doing some looking around and found this!
what ya think...im kinda interested in grabbing it.

ok guys well i attempted to install the 3.8 manifold and unfortunately failed
but it isnt all bad, luckily ill be able to get a full install here soon =)
The issue i ran into is that even though they look very close to being perfect fits but alas it will not work right off. the fuel rail mounting points for the sonata are about 1/4-1/2 inch on the rear rail too long and nearly a whole inch too long on the front rail, also the hard pipes that connect to the rails is just slightly a bit too close for the upper intake to mount just right so ill be getting the fuel rails and fuel line assembly soon to. but other then that i still test mounted the new intake and it will fit just fine although it is a bit taller then the stock unit thus there may be an issue with trying to re mount the dsm upper strut bar. sorry i dont have any pics of when i mounted it but my phone died but anyways here are some pics an a vid of the 3.8s

The 3.8 runners look bigger in the mani its self. This actually helps me with one question I had for my next big project 
hah so you gonna join me an take the plunge on one two?
oh yea you can see the difference also the pics dont show it as well but there is a good difference between the angles on the lowers on how shallow and sharp the angles are between them. also the injectors fit a bit tighter in the 3.8 but they mount in just fine...its just the mounting points for the fuel rails that differs

One so bi gI have to wait til next year when thecar is paid off haha! BTW ru gonna get us a dyno? If there is improvement I might take the plunge! I just have soooooo many project cars im working on right now!!
INSTALLED!!!!
Ok guys well i finally was able to install the manifold! and gotta say it looks great.
Anyways for anyone who is looking to do this there are a few parts you will need and a couple of bits you will have to rig so they will fit properly, and some things that will either have to be left slightly dangling or you could always go and purchase all the proper parts from the 3.8 azera to make it totally fit to oem specs.
On a difficulty scale from 1-10....1 being changing the box air filter and say 10 being an engine swap id say this is right around a 3-4...its a bit of a pain and will take between 2-3 hours depending on how prepared with the essential parts tools and space to get things together.
Now for the important part. Yes it adds power, but from my driving there is no difference sound or power wise from idle-4000RPM but after that point the car just sails along and pulls much quicker then before from 4k-redline and makes a much throatier roar too, now for those of you who dont know what the reason is behind changing the upper and lower intake manifold is because its a form of mechanical tuning that changes the power band giving better power at higher rpm and they also have better air flow to all cylinders then the stock intake manifolds . I will be doing a dyno here soon to verify the results as much as possible .
oh and here are some pics and needed parts
azera 3.8
Upper Intake Manifold
Lower Manifold
Fuel rails/Injectors....hah the one my set came off only had 45K miles on it so yay newer cleaner injectors hah
pcv gases nipple(part#292123C300)
Manifold gasket (part#29215 3C301)
left and right bank lower intake manifold gaskets
(part#284113C612 & 284113C622) now you dont need these but i changed mine since i just hit 90k and the oems were burnt
Throttle Body gasket( I got mine from FELPRO since the dealer wanted $22 for it vs $8 from them)
part#61560
The one on top is the azera 3.8s the bottom is the stock NF 3.3 ones

and this is it installed
