I have one of these and they work as advertised, a nice increase in both low and top end power and when combined with a tune is awesome

 

How hard is it to remove that intake manifold?
Sounds like a worthy mod.

 

It's pretty easy. Underdog has a really nice video on it. https://youtu.be/WnngSThaAMs

 

I saw the video, not gonna bother.

 

Looks like 75-80% of the work will have to be done anyway when changing plugs, so seems that would be a good time to consider swapping the manifold, if you don't want to bother otherwise.

 

Took me about 20-30 minutes . 100 bucks for 10-20 horsepower is pretty cheap and cost effective . ?

 

What most people don't realize is how restrictive the factory tune is, and any airflow type mods make a big difference. I did Intake, Manifold, Throttlebody and exhaust all before I got my tune and got gains. The tune was just icing on the cake

 

I've got a coule questions.about this now and am highly curious!

#1. Is this something that can be backdated onto earlier Pentastar V-6s as well, my 200 is a 2012.

#2. Do you need the whole intake, or just the lower half and is the top half the same shape on these as they are on the earlier FWD 3.6l like the Avenger/200, Journey, and Caravan/T&C?

 

1: Yes . It should bolt on to any 2011-2019 pentastar v6

2: Just the lower . And new gaskets .

 

I was on the fence about doing a ported lower but now w your info, I will be doing when plug time comes around. Pretty good gains for the $. Thanks!

 

I just made this a sticky.

 

I just linked this to AvengerForumz' 3.6l section and NAXJA's KL Cherokee section too, just in case there might be interest on either one.

 

Excellent post..!!!...I also will be looking into this...Thanks

 

I'm not touching mine because I had an Oil Leak and they replaced gaskets down there, so I wouldn't want to mess it up, plus I spin the wheels all the time as it is when I step on it, so more power would make it worse, plus it's not the most reliable car I've ever had to say the least, so I may not keep it for as long as I originally planned.

 

Modifying a vehicle for better performance is always a risk, no matter what the aftermarket modification is.

That's one thing I don't miss about my first gen 200 is that it was FWD. It's nice to be able to just go when I hit the pedal, regardless of if the road is wet or dry or if coming out of a corner etc...

 

This post is about higher flowing lower intake manifolds . A friend of mine turned me on to a discovery he made . Apparently on the 2016 and up Grand Cheerokees 3.6s and all the new vehicles with start/stop technology , they went with a different intake manifold that works on our cars. Its also part of the Pentastar Upgrade Engine (PUG) that used in the 2018 JL's.

I'm running it out of the box on my car and it picked up mid-range and top end. I could feel the power coming on much sooner .

In this picture , the top is the manifold out of the box. The bottom picture is a fully ported stock manifold . See how much bigger then port is ?

Part number 05281803aa is the new design and it's pretty inexpensive .
It runs 104.78 on some sites.

What about everyone else ?

I'm that guy btw?

 

Seems a little difficult for a first timer. Kinda scary.......... but if that’s what you have to do to change the plugs then you’d be dumb if you didn’t do the manifold it’s right there.

Thank You for video was really well done.

I bought the parts but was leery of doing this myself. "Fortunately" my car developed an oil filter housing leak which necessitated disassembly of the part that I had. I gave it to the service advisor and asked him to have the tech substitute my part for the old one when re-assembling the manifolds. Problem solved and I did not have to get my hands dirty... not that there is anything wrong with that!

 

Thanks for sharing this information, have been looking to see what else I can do to increase the power of my 200C and will be doing this in the future.

 

New to the forum posting but have read and done searches. Aren't there an issue with the larger opening of the lower and matching it with the proper upper? I know the flow and volume of the lower is larger but wouldnt that mean the port opening would be smaller on the upper? Everything I have searched and read(Even off Overkills site) is that there is no need to port the upper but just wondering if it's worth it to buy the entire manifold setup. This is on a 2011 btw.

 

I believe just the bottom ports where it goes into the cylinder head is bigger. no need to change the upper. doing mine in the spring ill post the results here.

 

Ah ok. That makes a little more sense. The picture in the first post made the top opening appearance seem bigger to me also.

 

Has anyone done anything with the exhaust crossover Y pipe.

It looks terribly torturous but possibly not as bad as it looks.

Thanks
Randy

 

No, but I had some catless downpipes made .

 

Where can I, get an upper intake And bigger TB for my 2015 200S 3.6?
thank you!

You mention the 3.6L GRAND CHEROKEE above , my question is regarding my 2016 Jeep CHEROKEE KL 3.2L
pentastarv6performance.com shows the same part for the 3.2L Cherokee KL, however, the Mopar parts sites does not reflect they are compatible.

Are you able to confirm that the lower intake part number 05281803AA WILL fit a 3.2L 2016 CHEROKEE KL 3.2L?
Also, is part number 05281803AA an actual upgrade from part 5184199AF?

Sorry for the late reply. Yes. It will 100% fit a KL. It's an upgrade over the stock lower .

 

Ugh. Mine went through 2 oil filter housings within a year. First time I didn't have the larger lower manifold yet...I took everything apart again to put that in. And a month ago is when the filter housing was leaking for the second time. I can now take apart and put everything back together with my eyes closed lol.

 

I have a 2016 Chrysler 200 S 3.6 does it already have the PUG upgrade? I don’t want to buy a new one for no reason and I can move on to the plug upgrade and supercharger

 

No car to date has received the pug update. The 200 never received the pug upgrade.

 

I don't think that the 200 ever got the PUG. It began on the Grand Cherokee in 2016.
For all the PUG improvements, there is a 2-step (lo lift/hi lift) valvetrain and a cooled EGR, etc.
Basically the top half of the engine is needed for the full benefit of the upgrade. Then there is the matter of the 2-step lift control harness and the PCM that controls it. An immense job.
I think that I would start with a wrecked, unmolested 2016+ Grand Cherokee as a parts donor. Whether PROXI could accept an alien control module on the bus is another concern.
Not a big boost in horsepower, but a very flat torque output through-out the RPM range.
No Direct Injection yet, the fuel (sulfur-less) refinement technology hasn't caught up yet.
