Looking for some input on the best cold air intake.

What do you do with the truck and what other upgrades do you have planned?

The two intakes that I like are S&B and AFE.

I haul a 10.5 foot camper and tow a 24 foot cargo trailer . I have'nt done any upgrades to the motor just a 3in levelling kit. I was looking at the AFE stage 2 intake, intake manifold and Magnaflow 5in exhaust!! Should i stay with the same brand ??

Thanks,
Ron

Ron,

The AFE Stage II is a great intake, but a word of warning.....you WILL hear your turbo singing. It is a loud intake. I had it originally on my truck before I did the twins and I put the silencer ring back in the turbo because it was so loud.

On the exhaust, I wouldn't do the 5" in your case. Until you start touching over the 500 - 550 HP mark, you really don't need it. Start tossing on something larger than a 66mm turbo (your stock is 54) and then you need the 5" to provide the CFM that the engine is gonna be pushing.

What's your tolerance for noise?....more importantly, are you married and what is your wifes tolerance for noise?

In terms of loudness, the exhaust go like this (from quietest to loudest)

1 - Stock
2 - Diamond Eye
3 - Magnaflow
4 - MBRP
5 - Silverline
6 - Straight Pipe

Let me know of you need pricing on any of those.

AFE stage 2 is a good intake. I have the AEM brute force and I like it, althought I wish the Workhorse would have been available when I bought mine. I believe the brute force and workhorse are the same with the workhorse being larger, (more cfm) filter..
I like the dryflow filter.. i hated oiling the previous cai's i had.

just did a CAI on my '04 5.7 CTD. Went with a K&N kit. Can't go wrong there. I've had one on every truck I've owned and their rep speaks for itself. Def makes the turbo sing....pretty much from didn't notice before to....can't be overlooked now. I don't mind it however. I am about to do a straight pipe and take out the silencer ring.....so I'll let ya know how that works out if your interested. Got my kit on Amazon.com. Can't beat the price. The website says it doesn't fit a 5.9L CTD but if you go to K&Ns website...you realize it is the correct CAI sytem. http://www.amazon.com/57-1532-Fuel-I...3095345&sr=1-1 Hope this helps. Good luck !

You didn't look hard enough then, because I can beat the price.....and I'm only a few minutes away from you in Salem.

Personally, I'm not a fan of K&N on anything turbocharged. They just let too much crap through and you can see it on the compressor wheels when you remove the intake or turbo.

They're okay on the track, but on a street driven truck they just let too much crap through. They're only a 3 layer filter.

You're much better off with an AFE Pro Guard (7 layer) or an S&B (8 layer).

The AFE will outflow the K&N any day and the S&B is the top rated oiled filter for stopping the crud.

K&N is WAY over rated.

I'm no expert....I'll admit that. Still new to the CTD. Since I already have the K&N intake tube and filter....what would you recommend replacing it with when it needs re-oiling ? and where would I find this specific filter you recommend. thanks for the input/opinion/advice.

Sorry brother, I didn't mean for that to sound like I was knocking ya.....

As for the filter.....I'd replace it. I won't run another K&N on a turbo'd vehicle.

When you get a chance, hold that filter up to the light, you can see through it.

For a replacement, you need to take 3 measurements.....

1 - The diameter of the tube
2 - The length of the current filter (or the max length that you feel will fit)
3 - The diameter of the current filter (or the max diamter that you think will fit)

Then we can get you a filter that will fit your existing hardware.

Coal Train, Im gonna be in the market for some upgrades here shortly, prolly tax time. My truck is a bone stock daily driver that i pull a gooseneck horse trailer as often as i can to do some hog hunting. Im gonna just assume from joining this forum the best first to do upgrades are an air intake and exhaust. Ive found a used MBRP 4" turbo back exhaust system and several Banks System stuff like the 6gun intake tube and air intake but am a little skiddish of the Banks stuff seems no one on here likes the setup. so will prolly make a deal on the exhaust only. also have a bone stock auto tranny that I cant afford to kill just yet . But any how what kinda price we looking at for the AFE intake. 2006 2500 4wd quad cab 50,000 miles. Sorry to make a short story long

Jason,

Before you start modding the truck, read this.....

http://www.doghousediesel.com/id12.html

Here are the big questions to answer BEFORE you start buying parts.....

1 - What do you do with the truck EVERYDAY?

2 - What would you LIKE the truck to do?

3 - How much power do you REALLY want to make?

Answer those questions honestly and we can get you on the path to getting the right parts the first time, rather than compromise parts for a short time.

It's a lot cheaper to get the right part, the first time.

And, Banks isn't bad.....it's just expensive and doesn't yield the power that others do for the amount you pay.

As for the exhaust....what do you want the truck to sound like?

9 times out of ten its just me in the truck, I love to hear an engine work. Ive always been a gas guy up until i bought my Dodge. Anything from mustangs to my current 67 Camaro. So I like loud. I have already removed my silencer ring off my turbo. That helped some but not near enough. I dont have huge plans for making extreme hp but since its possible would love to show some people up from time to time. The truck is my daily driver and hope it will be for a while. I know the tranny up grades are vital so will not do a whole lot until that can be taken care of. I really want to be able to boil the tires like your pic and have to refrain myself for fear of killing the tranny. Do you reccomend any gauges over the next set such as manual and digital. I like the pillar set-up.

Jason,

On the gauges, it's all a matter personal preference if you want analog or digital. Some folks like the analogs, some like the digital.

For an everyday driver, you want to keep the power mild until you do the trans upgrades. The stock trans can only handle 40 - 60 HP over stock before it starts slipping and heating up.

Do the gauges first, then intake and exhaust. After that, a good torque converter and valve body go a long way.

Power wise, if you do the analog gauges, you'll do fine with a Smarty Jr. If you want the digital gauges and power in one package, go with the Edge Juice with Attitude.

was wondering what it would cost for a cai system for my 2005 quad diesel 2wd, total stock, don't want it much louder than stock, just want better milage and towing, what do you recommend. I might level the truck up by torsion bars, thanks

For a daily driver, running a stock turbo, I really like the S&B.

S&B has a nice set up. 8 layer filter vs a 7 layer on the AFE and a 3 layer on the K&N.

It has a full air box that draws air from the oem location and from the bottom. The lid is also removeable for additional air.

I'll shoot you a PM with a price on one.

Best way to increase mileage on a diesel is add more timing.

But, in order to do that, you need a tuner or module.....preferably a tuner.

Now, to be flat honest, NONE of the mileage claims by most of the manufacturers is even remotely close. If you see 1/2 - 1 MPG increase, you're doing pretty good.

The onle that allows you the most flexibility with the timing and rail pressure is the Smarty. But, for someone that is mostly stock and wants the truck to tow and daily drive, you don't need anything more than a Smarty Jr.

Even running all the BS that I am on this truck, I stll get 16 - 18 MPG in day to day driving and 20 - 21.5 on the highway, depending on speeds and terrain. Those are hand calculated numbers, not crap from the overhead lie-o-meter.

Well thanks alot Coal Train for your honest answers. That's what I have been wanting to hear, but do you still recommend the cai and maybe the free flow muff, I also found out by looking under my truck I do not have the adjustable torsion bars, just springs so that means I have to get the 2" lift to level the truck. Some said I should get an alignment after that, doesn't seem like it should move it that much to require an alignment??

Yes, definitely do the air intake and muffler replacement. Those are the two worst parts of the air path on the truck. Along with a gauge set, those are two things that you do want to do.

As for the leveling kit, yes, you need either coil spacers or springs replacements.

The alignment is good to get after the level, but the main thing you'll need is the steering wheel to be recentered. When you do the level, it's going to force the steering wheel to be cocked slightly to one side due to the change in height affecting the steering components. That's usually to only affected part.
