I'm starting to prepair my self for the KEM/SPARTAN 200 or 250 Tune and i was wonderin what is going to give me the most power and be the best Air Intake for my truck.

The AFE STAGE II w/ Torque Tube

S&B AIR SYSTEM

XDI ??? DONT KNOW TO MUCH ABOUT THEM???

I looked at it but i dont think it would give you the hp and torque increase as greatly

I just installed an aFe stage 2 with the Pro Guard 7 today and love it. It was this one that I got Stealth Automotive. 6.0L Stage 2 Cold Air Intake System w/Pro-GUARD 7 from Raul at Stealth Automotive. I love it so far, the sound is great and there's a noticeable increase in throttle response. The turbo whistle is so good plus with the window open you can really hear it suckin in the air.

Now obviously you would need a different one than that for your 08 my truck is an 06, but I'd recommend this one advanced FLOW engineering : Review v3 :

Shoot Raul a PM and I'm sure he could get one for you quite easily.

Personally, I absolutely despise cold air kits. The filtration of the factory system is hard to beat.

With that said, I postponed putting a CAI on my truck until it was to the point of kicking on the check air filter light even with a brand new filter. At that point I didn't have much choice:rofl:

I ended up going with the AFE myself. So far, I like it. Definitely flows better and provided a pretty sizeable gain in power along with sounding like an overgrown vacuum cleaner. I'd rather stick with the stock intake, but I'm certainly in no way displeased with the AFE.

Thats what i was wanting to hear, Did you do the Turbo Tube Elbo??
 
#11 ·
I see what Matt is saying and it makes senses......I love my AFE Stage 2, but my thought is if you want the most from a CAI then it needs to be open and not sealed in a box like the the factory intake.......if your going to get a CAI thats sealed in a box, why not just get a high flow filter drop in replacement for your stock intake, its the same thing right?
 
#13 ·
So yall both think the best one to go with will be the OPEN AFE STAGE II w/ Torque Tube?? Julian did you get your torque tube installed yet??
 
#12 ·
honestly, every cold air kit is going to make you the sort of BHP that u can count on one hand, MAYBE two. I got the one i thought looked good, and had good filtration. (AIRAID) just my .02 but i really havent seen a diff in any of them other then looks and on occasion sound
 
#16 ·
I didn't notice a change in power at all, but i never dyno'd it before/after, and the noise diff is very slim. Helps to loosen the bolts on the CAI so you can giggle it in easier.
 
#17 ·
went with Airaid because they have done better R&D then the others. No CEL's and the filter works better down to microns unlike other.

I herad some of the early adopters of the AFE and the issues with the CEL so I went with Airaid.

I had a Volant on my old F160 (06) and I hated the sound it made. the truck had a resonace that was terrible.

just MHO

Ill throw a vote at the S&B

I installed a AFE stage II on my Duramax and It was a nice setup. But the "torque tube" is a waste of money :doh: It in no way what so ever does anything on my duramax. The only thing it is is a smooth tube instead of having kinks like my stock one.


Now I did install a S&B on my 99 PSD 7.3 and the kit is awesome! The kit is nice, went together smooth, and has a tube that goes to the front of the truck to draw air from the grille area. The s&B connects to the battery box differently so it even comes with a new battery tray. Its definatly a nice system.

Heres a few pics :thumb:

But the S&B just seems like you could take the stock system and put a high flow airfilter in it. I've always understood that the reason it was COLD AIR was because it didnt have to pass through the tube beside the radiator and the battary which is hot and heating the tube up so the air is not as cold. Not dowing anyone one with the S&B i realize its not throwing codes but KEM programmers is correcting the throwing codes.

Update, I'm going to go with the AFE II Pro Dry Filter system w/ torque tube.

Cold air comes from the outside, any air from inside the engine bay will be much hotter than the air that spends a split second between the radiator and battery.

I have an afe stage 2 and I cannot get the cel to turn off. Does it hurt the truck to drive it with this on? When I scan it, I am not getting any codes. Thanks
 
#23 ·
I don't think it will hurt the truck as long as you don't notice a power difference.
 
#24 ·
It picked up a couple of mpg's the power really didn't change. Seems like it is running ok. Need to get with one of the guys that's tuning with that air cleaner on, would help to maximize gains.
 
#25 ·
Did you get the Oil filter or the Pro Dry Filter. One problem with those Oil ones was that the oil was getting on the sensor and throwing codes... from what i understood. Just curious to which one
 
#27 · (Edited)
If it's setting codes you have to wonder what else it's doing. If the EGR codes are set then does that mean hot air is entering the intake through the EGR system? If so that would be worse than stock air intake hot air. The intake air is cooled by the charge air cooler whereas the EGR is not as far as I know about the EGR on these trucks. Maybe someone knows how it works.

Being a turbo charged engine you can't possibly be gaining much noticeable power increase as a stock engine. Only after other mods have surpassed the demand for air flow provided by the stock system should you see it make a difference other than sound and looks.

That being said it's possible that cold air intakes may provide some performance gains due to colder air. This would depend on conditions and could give less power in very cold weather and cause engine wear and oil use. Looking at the cooler and where it's at I am thinking the air is not too hot. Someone with a gauge could check this out.

I think the main thing with cold air intakes is getting the fuel mapping on the computer to compensate for the added air mass. Otherwise the engine is running leaner than it would for maximum power output. I think without the exhaust modified also they are kind of a waste, you are taking in a lot more air maybe burning efficiently but not expelling it efficiently out the exhaust. I would say they are necessary for a modified engine though, the stock air cleaner is too restrictive for a high output engine. I am not a big ecu controlled engine person, I come from the days of carbs, where when you add more air you rejet and add more fuel, I am sure the computers are the same but way more variables with the emissions.
 
#30 ·
I believe the only way to do any performance mods right is to get with one of the master tuners like Matt over at Spartan Diesel and use his exact set-up air cleaner back through the exhaust with his tuning profile. Every component you buy is different and if you mix and match parts and tunes you will never get a fast reliable set up. Otherwise it's just looks cool and costs a lot of hard earned money, just my previous race experience.

I have a 2008 SD and have just installed the S&B intake on it. I have noticed that it seems to make noise at idle that I have not experenced with the other intakes Airaid/ AFE, I expect it to be louder under power . I was getting about 11.4 mpg on the factory dash monitor. Can I expect an increase in mileage???
 
#33 ·
I just installed the AFE II PRO DRY SYSTEM and TORQUE TUBE and NO CEL!:happydance::happydance: I'll try to get pictures up.
 
#35 ·
I was told by a friend thats an editor of a Diesel Mag that if I like the engine not to run the S&B so I didn't... I'm a big fan of the AirAid, and their warranty too. AFE is a close 2nd and True FLow is my 3rd choice....Other than that, I'd keep it stock, but that my .02

If you running any kind of hot tune on the 6.4s you can't the truck "freaks out" I guess is the best way to put it. It trys to suck in more air then the stock intake will allow and the CEL comes on, power down, not to mention the strange azz noise it makes

I like it, I put the badges on the case. I think it looks really good..
