Wanted to start a quick discussion on air intakes since the situation for our truck seems pretty unique, IMO.

What I mean by that is that in every other vehicle that has aftermarket support, you've got your low end (weapon R, generic autozone, etc.) and then you have your mid and upper range stuff (K&N, Volant, Airaid, etc.)

For our trucks, we have multiple choices in intakes but since they all seem to be about the same price point, I wanted to get a discussion going to see which ones are worth the while or not.

I currently see 3 types of intakes out there:

1.) Open filter (legmaker, K&N*, AEM*, Airaid) (*open filter but heat shielded)

2.) Snorkel type (S&B, Volant)

3.) Topside sealed box (Vararam)


All of these options run in that 300-400 dollar range, with the exception of the legmaker. What I have seen in regards to reviews on the legmaker make me never want to even consider it.

Personally, I will never use an oiled filter. Too much margin of error and I really don't feel as if the oiled filter does anything that a GOOD dry filter can't do.

A friend had the Vararam and sold it because he didn't notice any change, and while I like the concept and love the look it gives the truck (especially with the hemi orange cover) I have to wonder how much of a volume of cold air it can actually get given where it's drawing from.

Conventional knowledge and everything I've learned to this point about automotive performance (across the 12 other cars I've had) seems to indicate that the S&B or Volant design is the most effective. It's filter is heat shielded, sealed at the top from dripping water, and specific efforts are made to draw air from the coolest points possible, furthest away from engine heat. If you weren't going to spring the extra $100 for the cold air snorkel on the S&B (a bit excessive when you're already paying $300 for an intake, IMO), then it looks like the Volant would be the better option because it's openings are a bit bigger.


So who's got what, and what gains have you noticed since adding it? Obviously it won't be earth shattering without exhaust and tune to match, but compared to the stock intake I imagine we should be feeling something.

Imm gonna get the Vara when I get an extra 300 bucks. Id also say the Vara probably gets better the faster you go (forced air in, but dunno for sure.)

I cant attribute my trucks top end pull to just the intake, but she pulls pretty hard from about 3400 up.

I will say I think it aides in the acceleration and the pull, and its definitely NOT starving for air. Id have to hook up my computer to the tuner again and do some logging, but the intake air is cooler (from what I remember) and Im sure its drawing in more air.

Id have to go back to a stock box for a comparison, but I don't wanna hook it all back up.

Personally, I like the vararam so far (5000 km's) and no you cant beat the looks!

I wonder how can that be. Before installing all mods I specially installed Vararam and Diablo only. The power it gaves after 100km/h (60 mph) is absolutely noticeable compare to stock one. Prooved at roll-on with stock truck - about 1 corps from 60 to 100 mph - just for fun, not serious rides.
Also there is to choose from that point of view if any aftermods wil be made. Like exhaust complete (not just a muffler or items from different producers) etc. The filter only will give nothing (in a view of feelng) except some noise and may be a couple of PS in ideal circumstances at the dyno.

So you said you installed the vararam and the diablo tuner...my stance is that any gains you felt were most likely from the diablo tuner rather than the intake. I don't think the intake hurt anything, but I doubt it did much for you in the way of real performance gains.

I'm curious to see what reviews you are talking about on the LMI. The mid tube is an appearance mod and has much bigger gains than you'd expect, but his complete one is no different than an AFE. I've used his hammer and true cold air intakes and they are top notch products. I've personally gone through an AirAid, K&N, S&B, and two different LMIs; I'm now boosted with a filter right on the blower.

Performance-wise on our trucks the Vararam has had the best results but I hate the construction and reliability issues with them, plus I personally hate how it takes over the entire engine bay. The next best performance has been the S&B which has performed just under the Vararam regularly for the track guys, where you see real world gains and not just numbers on a dyno. The Volant hasn't been popular because it has a very restrictive filter (relatively), though amazing filtration, and what I would run if I lived in a dusty environment.

If you are looking for daily driver-type gains then most CAIs are useless. If you want pure performance gains then you need to look at the type of driving you plan to do and buy an intake accordingly.

Top speed driving is served best by an open element filter with zero boxing in as you want volume and IATs will be near ambient anyways from air flow into the engine bay. You also want a comparitively textured surface to reduce the surface drag and increase boundary layer formation length inside the intake tube. This is where an intake like the LMI hammer really shined and truly performed on my '07.

Drag racing is best served by a sealed true cold air intake because you don't want to be pulling in hot engine bay air and have the pcm pulling timing at the low/mid speed to compensate for high IATs. If your only goal is to drop IATs then you have to look at the materials as well as the sealing. Metal tubes and heat shields can heat soak from the engine bay temps and this will warm up the intake charge when sitting at idle which can cause pulled timing in the first half of the track; Composite or carbon fiber are insulators and work best for preventing heat soak. I ran a modified LMI true cold air with the best results of any of my N/A tubes for this because I couldn't find a BFI for my '07. On the 4th gens the S&B and Vararam are the intakes of choice, even without the scoop on the S&B.

Now, look at the stock intake... it's already a true cold air intake but with a ****** mid-pipe and a poor paper filter. Dropping in a high flow dry filter and replacing the midtube with a better one (like the LMI midtube) that doesn't have the baffles to reduce noise and you're at the same 'performance' level as the K&N.

And on a side note, if anyone ever tells you they are running a CAI on a turbo diesel or boosted engine then feel free to call them an idiot because the intake charge is being raised 150F and a 5-10F decrease prior to entry into the compressor means SFA except to be another mod they can say they've done.

I agree with this statement.

How contributory.


Do a search on intakes in this section of the forum. Not one single comprehensive thread with information and experiences, including all different iterations of intakes for our trucks.

But hey, carry on.

Just remember, intakes are completely subjective, which is why a comprehensive thread has never been put together. Everybody wants something different and at the same time nobody wants to be told that the mod they did is useless or a waste of time, so you will ALWAYS get "I installed X intake and I'm happy with it". A few years ago I did a long winded thread on throttle bodies and all it did was create a major headache for me. I've been asked to do one about intakes but I refuse everytime because no matter what you put in front of people they will always disagree and claim they know better because they read it on the internets.

The combo will also make a BIG difference, so you can't just take the intake alone and say which is better.

yeah, that's why I wrote:

and that's why i'm telling it will work with all mods concerning intake and exhaust only. As I wrote before - each part separately brings nothing but when you put it together you have the real result.

you want a true fact, CAI look perrdy compair to stock ones. you want a good looking intake when you open the hood, get the one you like, you want an intake that provides power... invest in a kennebell or pro charger and quit complaining

You hit the nail on the head.

I was also curious as to what issues he was referring to the LMI. Granted I never installed one on my Ram, LMI is very popular on the Challenger and Charger forums and I have run tests that show that it drastically reduces the time it takes to recover from heat soak.

Well I agree and disagree on the intake...I bought a vararam back before I had a tune and I noticed nothing from it over the stock box..Sent it back to vararam no questions asked for a full refund..After I got the tune I decided to try it again just to see..Me and a buddy raced 4 times with me having the stock box then I swapped on the vararam and we raced 4 more times..The results went from him pulling me 4trucks to 100 to me having him a half a truck at 100 so I can say it def helped out..This was during cool weather!The 1st vararam I had was during hot weather so maybe that's why it didn't do anything for me and maybe it was because of the lack of a tune.I guess it's 1 of those every truck is different basis.I don't agree with their claims on their website but in the sense that they offer a no questions asked money back it's kind of hard not to beat because I don't think any of the other intake companies offer that.I also had the vararam on my 2010 LS3 Vette and they basically claimed the same gains and I can say that it put a lot of air in the engine from the design but I didn't see the gains that they claimed once again.They claimed 3.5-4 tenth off the 1/4 and +4 mph in the 1/4.Judging by what they claim that means the ARH long tubes and drag radials were only worth .1 tenth and 0mph which I don't believe!

I have 3 CIA. Before the Cam/Head mod I ran the Volant with the ram snorkel. After the Install, I noticed the speed at 100MPH really slowed. Bought the Vararam, the truck will hit 120 like a hot knife through butter. I like all my intakes. Personally it is better to run a closed box intake for reasons I will leave out for now. I did a couple mods with the vararam to make it alittle better. 1) removed the weather striping on the hood and black ducked taped evey hole and sealed the liner to the hood. 2) doubled faced taped 1 1/4 inch air conditioning strips over the existing weather strips on the vararam for a tight seal where the hood liner changes depth. NO WATER splashing up in the back corners. 3)left the ram snorkel in and modded it for fresh air in the engine compartment.

Who knows if any of it made a difference, but its fun trying to figure a solution to a problem.
