Any suggestions on the best cold air intakes out there? Pics and sites would be great.

Guaranteed........ leave stock.......add a flat K&N and modify the front snorkel. This weekend we found the DUB actually LOST 10hp......and that was back to back dyno runs for each one.

I will guarantee you you will run lower IAT #'s with the stock system.......like 40-50 degrees difference!

40-50 degrees... my IAT is normally only about 1-4 degrees warmer than the air out side when im moving, even if im only going 15-20mph

I have the gs CAI. im not a big fan of there quality, but i do like the k&n filter it came with, and it sounds great...

I vote for the Volant (from Southern Hotrod) with the snorkel mod and brake duct mod.

Just installed the Volant last night. Great quality. Not as blingy as others I have seen. Huge filter, sounds great, and the Butt Dyno said there was a very little gain.

isnt the mopar cai the same as the dub? if so you missed the comment where they lost 10hp from it.

Hmmm - I am not liking the sound of this. Can you give more info on how it is possible to lose hp by adding the DUB? I am not keen on going slower.

I think you would be very happy with a Volant.

I have 1 Volant left in stock. The price is $295 shipped in the 48 continental United States.

I would imagine because of the chrome tube and box. I'm guessing it retains a lot of heat over the stock plastic housing and rubber tube.

I have driven the truck down the highway and then gotten out and touched the tube to check after I installed. Its not hot to touch. :mad: :confused:

Of course I wondered the same thing myself after I installed, so I put that to bed.

Then my second guess is that the box does not seal against the hood allowing hot air from the motor to be sucked into the intake.

That has some merit because the way the box goes on at the bottom, it kind of just rests against the factory lower and does not seal that well.

Still - I would like some more verification that there is a hp loss. I am ok with no gain, but don't like a loss.

I think in general the design of all the CAI's are similar and the mention of HP loss is gonna be hit or miss. All the companies claim certain HP gains on their own website, which is probably backed up by a dyno run back to back as well. It's the modern world, people can prove just about anything while others can prove the exact opposite...Find one you like, or someone's opinion you trust and go with it. I have the DUB and it looks good, made some sounds difference, and I didn't notice a loss in power. It was actually referred from HHP where they do countless dyno runs with different aftermarket accessories.

I've looked into the CAI and once I looked at the factory setup I feel the best bet would be to modify the front scoop behind the grill and run a 3" hose from the brake scoop to the bottom of the filter box, once the silencer is removed. All this can be done under $60

The mopar intake tube in metal and will retain the heat over time and will cause HP figures to go down.

The two changes you just mentioned are referred to as the "snorkel mod" and "brake duct mod".

BTW, the Volant CAI uses a plastic tube as opposed to the metal tube.

All this testing was done last year.......an aftermarket CAI is worth 5-7hp period!!

The Mopar CAI is made by AEM it is a 4" tube that tapers down with the rubber sleeve. The design does not isolate under hood heat.....that is obvious by visually looking at it. You can also invest in a Actron Scanner and monitor you AIT sensor vs the stock box.

The GSM CAI is a 3" CAI tube similar to the stock size it is isolated much more than the Mopar by the sheetmetal box that goes around it. It seems to offer better SOTP throttle response due to the 3" design that will aid with velocity.

The DUB and Airaid use the stock box and some extension so when you close the hood it theoretically seals the filter.

The stock box is in fact sealed. The tube is heavy rubber which in my opinion would be more heat resistant than a metal tube......dont you think?!?! The air is flowing through a flat panel that pulls air directly from the front grille...hhhmmm that would be air cooler than from under the hood. If you slightly modify the snorkel by leaving the right side and floor and just remove enough of the left side you open it to direct incoming air. I personally have seen 30 degrees difference using my AIT sensor. You can even remove the baffle at the bottom of the box more more air if desired.

All this is just my opinion ......some base on dyno test....but what do i know???

I may take the stock inlet tube and drop in K&N to the B&G dyno session. I'm curious to see if the Dub is in fact costing me power.

Honestly, I am just looking for the real deal here. Do I change, do I not change. Do I just change the element to a k&N? I have a 1996 Cherokee with a custom set up in it (pic in icon) and it made a huge difference, but from what I am reading, it's all over the board. I would rather save the money and put it into something cool. Like a supercharger for instance. :)

Talk about on the ball. So the Mopar actually gained over stock? Did you use a K&N drop in or the stock paper filter?

Anyone have an opinion on benefits of using something like the 'thermo tec cold air intake wrap/shield'? General consensus is metal intakes (DUB) causes higher intake air heat, so what about wrapping it for track days or anyday? I like the look of the DUB, gonna go well with my polished intake, BUT I like performance better. Maybe those of us with the DUB can have both. The thermo tec wraps are on Jegs for $45. Need to check fitting, I'm not sure of the parameters of the DUB - this fits anything from 2.5 - 4 inch diameter and up to 36 inches length.

front air scoop mod.

...real quick look through the grill (pass side) see factory scoop...
1) remove grill (puch pins easier than it sounds)
2) pull scoop that point to the left at 90* angle.
3) cut scoop to make it face front
4) widen and tweak if you so desire


duct mod.

Since you prolly won't be lapping Laguna Seca with your truck....
1) pop "cup" out of bottom of factory airbox.....or aftermarker CAI?
2) look at how you can feed a hose to bottom of box.
3) remove pass brake air duct, trim if needed and connect hose.

These 2 tricks alone are probably worth over a tenth and 2 mph?

Goodluck.

I have the DUB and I liked the way it looked, but I was concerned about the fact that it would heat up. So I wrapped it with thermal header wrap. It works very well and love the performance I have gotten from the 4 mods that I have done. I have magna flow with the resonators removed, Dub intake, snorkel mod, and B&G stage 2. I will be doing a stage 2 heads and intake soon and hopefully a supercharger as soon as someone comes out with a twin screw blower. But that may be to long to wait! LOL

WOW!!! all this talk about crappy different cold air intakes and not once did anyone mention the best one. Well, Bwoody that is. So if you want to buy a cold air for the jeep that will make a difference, then buy a Bwoody and forget that snorkel crap. For instance, i had a stock 07 with the snorkel, brake duct mod. I would race my friends stock 06 sti every day, and would lose by a car or two on average. After installing just the Bwoody i am pretty much always even with him, its down to who gets a better launch. With the 180 t-stat and borla s on now i am always ahead a car or two. So do whats right and purchase a Bwoody.

Some good points here...

I refused to run chrome smooth tubes in my Viper due to power loss thru heat-sink...

While the 6.1 does not run as hot as the V10, it still puts out considerable heat...

Regardless...

I installed the Mopar (so as to retain factory warranty)...

I suffered no power loss whatsoever...and the exhaust note is much more aggressive...

While I have no dyno numbers for you, I can guarantee there is no loss of HP due to the metal tube...

If they cause the motor or driveline to fail in any way, they most certainly can (especially the programmers, UD pulleys), even if they are Mopar parts.
For instance hypothetically with a programmer, the reduced torque management and increased hp/tq may at some point cause a premature transmission or other driveline related failure.
They have to prove that the aftermarket part caused the failure in order to void your warranty, but just remember, they'd rather pay their lawyers a percentage than give you a new trans for free.

If that was the case, then would there be a way to prove if that failure was caused by said parts if i where to remove them prior to claiming warranty?

As far as programmers go, Diablo claims no, but we won't know for sure for another week or so. I guess it depends on the specific event/application/dealer in question. For example if your aftermarket CAI caused your motor to hydralock (which again isn't likely) you might have a tough time.
