6.4 Intake Manifold Swap: What You Need To Know! 

These engines do not need any type of upper valve train lubrication whatsoever so that extra oil that's in your intake manifold he is simply condensation of the fuel/oil vapours mixed together in the process. When the vapours reach or intake manifold with it, obviously being a lot cooler than inside the engine causes it to condensate similar to your toilet on a humid day and then run down the side of your intake manifold. When I emptied mine, I had at least a half a litre that was taking a precious air space that could've been used for the combustion process. The PCM doesn't compensate for that space taken up by the oil which creates a performance issue. If you clean your throttle body once a year by removing it, you might be able to catch most of the oil before it goes into the actual intake manifold itself like mine had.. it took me 10 hours to wash out all of the engine oil that was caked on the inside of my intake manifold mainly on the bottom. I must've went through a bottle of dawn, dish detergent and hot soapy water along with cover cleaner and a leaf blower to blow everything out to check for any remnants of oil. Then I bought a baroscope to check the insides to make sure everything was moving OK and no more oil was inside. I cleaned up my throttle body as well and then when I put it all back together I thought I had a new truck. I didn't know what happened and then it hit me that all of that space that was being taken up by the oil, not to mention the degradation of the fuel and air mixture entering my intake manifold because of PCV GASES that robbed my fuel of octane. This is why the scan is very important. It doesn't necessarily net you any gains per se in horsepower but as far as performance, it allows your engine to run optimally with your oil lasting longer because it's not diluted from the fuel and air mixture by gases, thus increasing the light expectancy of your engine. as per for air induction system, it's a must an absolute necessity because of the added flow by due to the higher pressures inside the engine cylinders

The 5.7 and 6.4 truck intakes both have active runners and flow very similar numbers

Wow that must be awsome

How many hours power if i exchange 5.7 to 6.4 manifold i have ram 2018

Great idea on the oil sticker. Because them Walmart employees who change the oil, well you know 😂

Why are the switching that say lock ontop the manuiful

I have a 2008 5.7 can the 2014 6.4 manifold work with it.....? Ty

Sweet build. What cold air intake do you run with your 6.4 intake? I have been looking at the sb cold air for 2014-2018 2500-3500, will one of those work out?

With early 5.7 non eagle intake to the 6.4 do you know of any additional things that may be needed other the than 5.7 eagle intake spacer

For someone thats not too inclined on building parts can u rate 1 -10 on difficulty. Dunno if I should just pay someone

Are you still liking the intake manifold? I’m about to pull the trigger, but I’m going to go with the 6.4 injectors. I just can’t find info on which ones to get..

I'm look for intake manifold for my 07 Chrysler Aspen 5.7 slowly working on

My challenger rt 2016 have 3.09 lcd And 6.4 shorty headers And afe s3 intake Is the ported 6.4 intake manifold worth it?

@TunedRAMS so I’m planning on buying one of these but I live where it’s crazy wet all the time do I need to put a cold air intake on the 6.4 or can I use the same air box with modified hosing?

Im planning on doing that to my 20 rebel.but modern muscle extreme told me everything comes with the 6.4 intake. Only thing i had to add is spacers and c.a.i.and bettrr throttle body...any thoughts.

What else do I need with this change? Tune alone? I have flowmeter 50 HD muffler and upgraded air filter with gas paddle commander.

That man just did matt brown dirty 😂😂😂

Does the spacer go on top of the fuel injector?

Do you need a tune right off the bat if im still going to run 5.7 injectors

Hey I jus got an rt Durango what parts do I need jus 6.4 manifold, or they more to it ?

Can you use 5.7 fuel rail on the 6.4

How much horsepower gain?

What throttle body did you use ? 5.7 or 6.4 ?

Upper lubrication? 😮

I’m looking at building my Ram to push 1000HP, I need lots of advice to upgrade my 5.7L. Biggest problem I have is money as I know how expensive it is

When you modify and engine for performance the factory oil recommendation is no longer relevant. 0w40 would be much better.

Gasket between plutonium n intake is blown..... Common problem with them

perhaps the weight of the fuel in the rails account for most of the difference.

You never flipped them over and did the runner size difference lol and it’s heavy cause it’s still full of fuel from your truck 🤦🏾‍♂️

UH!!!!!!!

Are you changing manifold, or huntin fo wabbits

Why don't you put a 6.4 hemi in your truck?
