Cold Air Intake

[blkdodge]

Looking for some recommendations on a cold air intake on a 2012 Ram 6.7 Cummins.
Thoughts and comments appreciated.

Bhaf is a gimmick unless you're making some real power. Period. Not going to beat stock filtration and a cold air filter, by itself isn't going to free up enough air to spin the turbo that much easier resulting in 100deg egt reduction. And if it does, who cares as long as you're still in the safe range.
Coming from a guy that mods about everything, I wouldn't give $10 for one.

Is the stock intake on the Cummins powered Ram so poorly engineered that the engine is starving for air or running hot? My four Cummins powered Rams had factory cold air intakes and rarely did the air filter minder even move. Other than extra noise and an ultra cool sticker for the window, I see nothing to gain from an after market intake gimmick.

AFE does make quality products. Oil samples always came back with good silicon numbers on my 98 12V. That engine was tuned with no sensors to get fouled.

New truck gets OE filters.

I've used the AFE pro 7 since my'03 Dodge/Cummins had around 6k miles. My trucks have to last many years and wanted to help the Cummins run cooler.
I use the Westach boost/egt gage and find the AFE drop temps in the 75-100 degree range overall over OEM filters when towing or running 85 mph in 100-110 degree hea.
The truck is getting close to 300k miles on the odo. I'm satisfied with the results.

Seriously....WHY?

What do you think it will accomplish, what are you wanting to accomplish.....WHY?

Settle down.....go for a walk, take a deep breath?.........
But I agree, no need unless you're making some serious power. I can't suck the filter minder down on my 07 running around 450/950 at the crank when I hammer down, so that tells me it's flowing pretty good.

My Son's 98 RAM 24V 4x4 hit 103 at 12.78 at Spokane, his truck dynode 430. He only had a screen on the turbo intake.

I am not going to jump on the "you don't need a cold air intake" band wagon like just about everyone has done here since that is not what you asked. You are a grown up and can spend your money as you please.

S@B is highly rated by many tuners. The one thing I noticed in an install video is that you have to cut your MAF sensor in order to extend it to make it fit.

The AFE momentum is another on that is highly recommended by tuners. Very easy to install from what I have seen. If you go with this one then get the Pro-guard 7 filter option. AFE recommends this newly revised filter for all diesels especially this in dusty conditions.

I believe both with give you more turbo noise, but I don't know how much. I am not sure how much both will lower EGTs either. I do know that your biggest restriction on your truck is right where the intake horn comes into the manifold. That is where your heater grid sits and it opening is small even without the heater grid.

Snorkel is about the only true "CAI"

CAI terminology has morphed in to being applied to describe any aftermarket intake, whether it draws air from outside of the engine bay or not.

My '04 Dodge gets its' air from the fender well, not the engine bay. How much cooler do I need? Not much I think. JMHO.

There are only two mods that I would recommend for that truck. The first is a turbo saver. When you turn the engine off it will continue idling until EGT reaches 400. Really nice addition. The other????

Every GM truck with a diesel in it since the 6.2 diesel has had a CAI in it from the factory.

I haven't seen all other years and makes but I would imagine it would be the same.

Agreed for raw horsepower. But. Does it help EGTs run cooler when pulling?

The truck is only going to pull the air it needs for the fuel burned, so if the intake can handle more than you are asking of it already making it less restrictive will gain you nothing. Now if you can get cooler intake air that can help, but then you are looking at bigger more efficient inter cooler or pulling intake air from a cooler location.

There are different requirements or best tuned intake needs between a gasser vs diesel

Diesel has no throttle, so it needs to have as open as possible...whereas with a
gasser and a throttled intake, it needs are way different during low rev's or
power situations

So, not comparing apples to apples between a gasser's intake needs vs a diesel's

Keeping the intake as cool as possible, with-in it's spec temp range is always
best....they why of an inter-cooler exists for forced fed...even diesel

*ANY*

intake system that ingests engine bay air is not worth
the money or time. Reference above about getting the coldest air

Been there done that during my 20's trying most all available low restriction
intake air filters. Good old OEM for me and if available, get the HD versions
From my 64' MGB's side draft Webbers w/o any filters to my Dune Buggy w/o filter.
Not worth the engine rebuilds that caused or contributed to...

Some OEM are not good enough, but that is on a individual basis, IMHO. As stated
above, today's OEM's do a pretty good job of it and as much as folks complain
about CAFE/EPA/etc requirements...they all also improve the breathing (in and out)
of our vehicles today

There are none that I liked and made my own...just because I wanted to...
