What's the best Intake/CAI kit??

[DwDrummer]

I'm looking to buy a Intake/CAI for my 08 Tahoe 4.8 and was wondering which was the best performing intake for the money? At this time I'm not planning on putting a aftermarket exhaust so would this hurt the performance of the intake?

I've thought about getting the Airaid Jr tube but didn't know how good it would be. Let me hear your opinions and advice. Thanks!:Handshake:

Thanks,

Biased, but love my AEM.

[AtomicHoe094]

volant....

[Modded]

I say AfE, AEM and Volant are all good.
Truckin proved the Airraid complete intake kit to add 22HP to a 5.3 07 Tahoe, though Airraid said it will only give a 19HP gain.
Airraid def. has the best HP gains that have been proven to me yet.

[DallasD]

I have S&B and it is a nice fit and look. If you are not wanting to spend a lot of money you can look at spectre it looks like the AEM kit but for half price.

[DwDrummer]

Thanks for the help if I get the Airaid JR. kit and don't put exhaust will it help out any??

Thanks,
DwDrummer

[scottrick]

Volant for me.....call them and they might make a deal right now.....

Just changing out that stock intake tube/resonator will make a heck of a difference.

[OKLAGMCRUISER]

if you can find a used UPD lid/tube they are nice too!

I thought it would have to help some. I like the way my factory exhaust sounds now but would like to have a little more power/throttle responce and help the MPG!:Handshake:

[NoChrome]

I made my own for about $75 and I am currently working on a ducted ram air kit for it. I could post pics, but you guys would vomit and the uh condition of my engine bay.

Love my AEM, hit me up if you want one for yours I give a hook to the homies off the forum :cheers:

[nytahoe]

i have the jr kit in my truck. i got it from jenn and bb. seem to help love the sound. cant keep my foot out of it.

[snowjay]

Out of curiosity, anyone know who makes the one for GM?

http://www.gmaccessorieszone.com/Chevrolet/2009/Tahoe/Performance%20Air%20Intake/?tx_gmshopb2b_pi1[type]=gm

It's a little pricey, GMPD has it for $327. Looks cool though.

[Max]

AEM makes the gmpp kit, I wanna say their brute force makes slightly more power but they both utilize an oil-less filter.

[yugoballa823]

i have a k&n and have no complaints

[07Denali]

I just got my Volant today with the powercore (100k/no maint.) filter. Installed in 15 minutes with no instructions necessary. Sounds tame under normal driving, but romp on it and it sounds hugely different!!!

[05nali]

anyone now how the k&n compaires to the aem. i want to get one. price?

That doesn't make any sense, 100k? I clean my filter every 5k, takes 20 minutes.

[MASS-HOE'Z71]

I don't notice too much of a difference between my k&n and the aem a buddy has on his silvy....cept for the price, I got mine with the chrome tube for about $75 from a neighbor but I don't think I would spend the $300+ that they go for new, sounds great tho but I think I'd be just as happy with an aem

[Volant1]

Thats the difference between 8in of filter and 8ft theres more surface area for dirt to cover and nothing for it to stick to

I think Im with max on this one, sure I dont clean my filter every 5k but, 100k is a long, long time. I dont care how bad ass your air filter is, it is eventually gonna run out of places for dirt to stick or its just letting smaller stuff through that would normally clog one up.

[Volant1]

It isnt a Volant filter, its a donaldson, same flute that is in the black hawk helo, your not dealing with a cotton, poly or paper filter its nano fiber, you do not service the filter so there is no break down in microns like serviceable filters, its .001 micron from start to end like I stated above there is nothing for the dirt to stick to so it does not build up, we also put a downward angle on all of the filters so large sand and dirt fall back out of the top, also you do now that every time you service a filter your letting in more dirt right?

[Max]

I'll stick with my aem that collects mad dirt every time I clean it :cheers:

Here is a little food for thought i just picked up this intake off eBay for 67.00 shipped may not be the best or the nicest but it has been working great for me.

Here is the eBay link for the item......

and here is a few pics of it installed

These pics are of the intake installed on my 07 Denali

[dynamitekid]

hey i got a afe Magnum Force air filter box, with afe pipe.. put a airaid throttle body on and makes a differnce on my 07 yukon.. also put 1 chamber flow master with 2 tips out the side.. sounds great

[wot_denali]

Air aid box keep the stock tube and save your money

[JennaBear]

The stock tube is what you should be changing, as that is where all the restriction is. Check out the resonator on that thing.

[vonneffdobermans]

[Blkout02]

What's better arm brute force with oil free filter or aem cai or a kn cai or are they just all pesonnel peference

[JennaBear]

Anything that changes out that stock tube will be just fine. Go with what you want, they all perform pretty close to the same.

[Blkout02]

Is there much a difference between a dry filter and one that contains oil?

[madmac]

Back in the bad old days, resourceful hotrodders simply replaced the air filter with one that was too tall. This left a gap all the way around the air filter lid, bypassing the restrictive snorkel, and thereby increased air flow to the carburetor at a cost of, well, nothing. A four-barrel carb made a wonderful howling noise. For you youngsters, a carburetor was a device... never mind.

In that spirit, when I had a 1975 Volvo with Bosch fuel injection and no money for accessories, I simply drilled dozens of holes in the air filter canister. I have no idea if it got better mileage or more power, but it seemed to have better throttle response off idle and sounded stronger.

Don't get me wrong. I love those polished tubes and dashing red filters, but has anyone tried drilling holes or cutting openings in the stock air box? Of course it would no longer be a true cold air intake, but then most of the ones on the market look like they pull hot air from the engine compartment, too.

I did something similar on my '05 Tahoe. I detailed it here: http://www.tahoeforum.com/showthread.php?t=12062

I now have a '07 Denali and haven't yet looked to see if I can do this again.

[coopiesb]

my .02 cents......... ive ran aem in every vechile ive had

[Excon11]

Im looking at a fujita cold air intake for mine. Any body herd good/bad things about it? Thanks.

[mikeb33]

I looked at the stock tube and it doesn't seem that bad. I do see the ridiculous looking resonator, but how does that hurt? The resonator is an acoustic sound canceling design, how does it hurt airflow? I would think ample diameter and smooth bends would be the most important, which the stock tube seems to have.

[madmac]

By resonator, if you are referring to the closed extension on the air intake projecting toward the driver side, the purpose may be this.

I am no automotive engineer, but if I remember correctly, Yamaha uses a similar arrangement on their ram air intake for the R1 or R6. The idea is that it stores a volume of air held in reserve to be used to aid in transition for sudden throttle openings. But I could be wrong, I often am.

[JennaBear]

The resonator (helmholtz) was put in the tube by GM to make the intake quieter. Here is a good explanation as to how it works:

http://en.wikipedia.org/wiki/Helmholtz_resonance

[mikeb33]

If that is true, I can't see a downside to it.
I still think it is a sound canceling thing. My 05 was louder with the Airaid jr tube, basically the same tube, without the extra chamber, or resonator.
I'd like to see a dyno with and without.

[JennaBear]

If you read that Helmholtz principle link I posted, you will see that it is tuned for great airflow at a specific RPM, in the Tahoe's case ~4K RPM. This is also proven in dyno testing.
