Looking to purchase a CAI

[BigRed76]

I have an 08' Denali and wanted to know what is the best intake out there for it. Also .... does anyone have (or can someone please shoot) a short video of what the intake sounds like when you turn off the car with the hood open? I remember years ago installing a CAI and when I turned off the car you heard a hiss that I was told was the air rushing out (not sure if I was being fed $hit or if that was true) but want to hear an actual intake LIVE .... thanks in advance!

Some of them do make a nosie at shut down (K&N) or similar. You should look into AEM Brute ForceDry Flow filter, it does not make any sound on shut down. It is a great CAI and made the most power on the dyno when compared to the K&N, Fram, Outlaw, GMPP CAI. Good luck!

Not sure what sound you are talking about at shut down? I have had the best in both Volant and K&N and never heard anything at shut down. Both intakes are great, highly recommend either of the two. AEM is also a good product, I have never ran one in a truck, but I have in other cars that I have owned. To be honest, I dont think there is any real HP differences between the "GOOD" CAI's. Just get one with an enclosed air filter box, otherwise you suck in to much hot air which defeats the purpose of a CAI

Not quite so. We dyno tested several CAI and there are power differences between them. Also the whole "eclosed" air box deal is not true. My IAT are 5* above ambient temps and its open element filter.

Interesting. I think I would have to see it to completely believe that.

What is it that you need to see? If you want to see the dyno graphs and all the logged data go on silveradoss.com and under the bolt on section it is a sticky there about it titled CAI WARs.

i started with the airaid tube and a k/n drop in filter. it made the engine louder. i just installed an afe stage 1 kit..its pretty much a closed box with cone filter..now my truck seems more quiet..i am pleased..no hissing but i know what you are talking about, my 95 yukon did that. if you get something enclosed you shouldnt hear much

I am happy with my Vararam intake...I wrote a review when i installed it...

It goes back to a LONG discussion on closed box intakes vs. open filters. IMO more air flow through an open filter is better than channeled closed off air flow because it restricts the amount of air

With that said, I replaced my stock paper filter with a K&N drop in filter. Only reason I didn't go with an open filter is they get dirty fast!!! Plus I get more power from my tune than I would ever get from an open filter and these trucks won't ever see the power levels that you really need an open filter for

Art was helping at the dyno for the results I posted in my intake thread.

bummer that the volant kit tested was the 15953 that we stopped making 5 years ago in real world conditions a closed box will out perform a open element kit any day, any one can get a high number with the hood open and a fan blowing on the filter. But dont take my word for it just look at everyones products now everyone is going to closed box CAI's

 

[JennaBear]

Who tested it? I would be interested in the results?

Very interesting. That is what I have always thought, glad someone can finally back me up on that.

 

[JennaBear]

Anyone can get good HP numbers on a DynoJet, but IATs are what are really going to matter.

Everyone is NOT going closed air boxes. The real tests are INDEPENDENT parties so there is no biased results. We have dyno AND street tested serveral CAI and let me tell you my OPEN box CAI (AEM Brute force) is only 5* above abient temps. Also do YOU have any proof of what you are stating? Have YOU tested serveral CAI? Just curious.....

 

[Volant1]

A 5* above outside temp reading is going to change up and down as you drive so you cant base results off one reading, As for proof everyone in the intake ind knows one another we share parts, filters, ideas. its not like chevy vs ford where everything happens behind closed doors. We have s&b and AFE guys over here ALL the time we also buy there filters, As for closed box and everyone going to them AEM, K&N, Banks, S&B, AFE and every other real intake company currently and are producing closed CAI's

LOL.... I really hope you are joking. I never said that the 5* ambient temps would not fluctuate. Of course they are going to fluctuate with stop and go traffic and what have you. Aslo you never answered my questing about real world testing? What software do you use to log data on other CAI to compare different IAT?

First time you stated "My IAT are 5* above ambient temps and its open element filter"

As you can see you stated it twice so what I wrote was not a joke, We use autodyn30 software at volant

 

[WICKEDOWESIX]

Well that's too bad you can not take you autodyn 30 software on the street for some real street and track testing to log the IAT. For the record, the open element CAI outperformed the closed box CAI on every aspect metric from MAP, IAT recovery, power output......

how do you all feel about all enclosed but the side facing the fender? any diff?
