Air Intake Kits and Intake Manifolds
 

My truck's motor is bone stock and I would like to start looking at some hi-po goodies, that will help with power and fuel mileage.

Concerning the aftermarket air intakes:
1) Are the oil-wetted air filter elements ok to use, or should I look for a dry filter element kit?

2) What are the good air intake kits, S&B, AEM, Bully Dog, etc??

Lastly, are the aftermarket intake maniolds a good, worthwhile upgrade? I see a number of companies making them such as CFM+, Banks, AFE, etc.

Thanks for any and all info!

I cant answer the manifold question but for the turbo side of the intake just make a wilys whistler its cheaper and bigger than the rest. If you havent seen it just do a search for Willys Whistler and enjoy

you wont get a huge increase from the manifold. they might help a little but ive ran the ats arc flow an the banks high ram and neither one were huge increases in power. I would build your own intake with an afe stage 1 or 2 filter. its not that hard to do. if you can work on your truck an intake is very easy to build and it will save you about 2-300 if you make your own setup.

I still have an oiled filter and haven't noticed any issues on my afe II. Some ppl have gone to the prodry filters, but I can't justify one for me right now.

With being a diesel, and having a turbo, what CFM does the 5.9L motor produce or is capable of pulling?

It'll suck a golfball through a garden hose. [laugh][laugh][laugh]

Surely you got a good look at the stock piece while you did the intake swaps?
The stock intake airhorn is like the banana in the tailpipe. Anything would help there.

There are plenty of ppl making 500+hp with the stock horn. It is not terribly insufficient, just looks like it. Aftermarket horns help, but only to a certain extent, even on high horsepower engines.

I didnt notice any increase with the new air intake horn. I felt alittle with the AFE 2 intake. However, for the money I would do the willy intake. I wish I did.
The only real advantage to the aftermarket intake horns is they have already tapped ports for water meth, gas, boost. I bought the GDP one. Simple install and looks nice. My .03

VIDS please!!!

I'm running a dieselpowerproducts cool hose with an amsoil nanofiber drop in filter. I like it a lot. The cool hose isn't that expensive either, you can use it with the stock airbox and upgrade to a conical filter later if you wish.

ya, the air horn upgrade definitely has it's limits, but I just cringe whenever I see the stock horn, the flow restriction in that piece is just ridiculous. [duhhh] I need a beer just thinkin' about it. [verymad]

That's why I went ahead and changed mine. I was also aiming for a better look. The CFM+ helps out a little with the egts. Later on down the road it will serve a better purpose.

This huge dryflow system is the largest that will fit within the stock engine compartment:

I was looking at the CFM+ units, but I ended up with an AFE Bladerunner....should arrive shortly!
