Cold Air Intake for 07 H3 - Page 2

Guys,

I just received a K&N Air Charger Cold Air Intake P/N #63-1095. After looking on ebay and this forum last week I ASSUMED it was the right one for my H3 unfortunately it isn't. I have an 07 H3 and it simply won't work...

The Mass Air Sensor and mounting bracket that bolts to the intake tube is different that the 06 model and 07. The 07 mass air sensor is so large it won't even go into the hole on the intake tube, nor would the stock bracket align with the holes in the new tube.

I wish I had called K&N first like Obie1 did, I didn't realize the darn thing wouldn't fit, nor did I see anywhere that it wouldn't work.

So....... if someone wants a K&N CAI for an 06 H3, I have one! The vendor will charge me a 15% restocking fee if I return it, I've not talked to them about this yet, not sure if they'd take it back at all after it's been opened. I unwrapped everything out of the box and put the seal around the air dam and bolted the vertical bracket to it. After doing that I was looking at the air sensor assembly on the Hummer and looked at the tube and realized it's not going to work.

If someone wants this one for their 06 let me know before I send this thing back. Please send me a PM if you're interested.

Thanks!

      Sorry to hear that the K&N did not work out. I am a K&N fan and have used them in the past. I pointed out to them that some vendor sites list their CAI's as fittting both 06' and 07' H3's. Their only response was "we do not make a cold air intake for your vehicle". They would not say why.Now I know there's a good reason.
 Your best bet might be to send it back to the vendor. For someone to buy it from you, you might have to make them a better deal than 15% off.
  My patience wore thin so I took HumRluvR's advice and ordered a True Flow.There a couple of interesting twists with the True Flow 1) their tube mounts between the mass air sensor  and the throttle body- so your problem wouldn't be an issue and 2) if your dead set against using a foam element, since they maintain the factory air box, you could run a K&N filter, which they do make for the 07 H3.(All though you have to buy two filters).
 I have every reason to beleive the True Flow will be a good system.
        Good Luck with yours.

 My hummer doesn't have a cold air intake yet but with my old car I did install one. It's a good add-ons to increase performance inexpensively. I've had this vw cold air intake with my bettle. Aside from bringing down the temperature of the air going into a car for the purpose of increasing the power of the internal-combustion engine, it also increases the appeal of a car by changing the appearance of a car's engine bay and creating an attractive intake noise. Hope you get a good one!
 

Peanut..what kinda HUMMER you got?

fishing for a turd???

I own an H2. I know its a shame that such a tough and powerful ride doesn't anything much to boast of in terms of engine function . Soon I am planning on having the CAI my Hummer deserves at present, what it has had many bends and twists that restricted the air flow.

I was looking at my stock intake system, and I was reviewing the resonator box and the accordian like intake tube and the breather box... It's quite a large and convluted system... that doesn't look very effecient.

However, looking at the way all Cold Air Intake systems work, they all have a dam to seal it off from the engine compartment and "Only take in cool outside air". Well, I'm sure they do, but I'm looking at my stock system and I'd have to say it is a cold air intake system as well...

The filter is in a sealed box, so technically it is only intaking air through the hole in the frame and out the right side of the engine compartment. Now isn't that cold air intaking also?

Seems to me that the problem is the filter type, paper is used rather than layered gause as the K&N or the foam systems and a smooth intake tube between the breather box and the throttle body. The True Flow seems to be designed to do just that yet leaves the stock box in place, still a cold air intake system right?

I guess I don't see the difference in the aftermarket air dams and the boxed in stock filter case, they both intake air from the same hole on the right side of the frame and both are blocked off from the engine compartment, just by different methods.

If K&N would make a short tube that connects the throttle body intake to the stock airbox so it uses the stock 07 mass air sensor (which is on the stock breather box) and emission return tube in the filter breather box too. They could change the coned filter in the 06 model with one that would fit the 07 stock intake boxm maybe just use their current OEM replacement H3 barrel filter?

Heck, this unused K&N 2006 intake system I have I could probably cut the tube with a hacksaw and use the provided silicone couplers to fit it between the throttle body intake and the stock filter box with the stock mass air sensor, the accordian tube comes off the stock breather just ahead of the mass air sensor as does the resonator box over the throttle body, just like the True Flow system uses.

Not sure with your car but what I know is about the volkswagen coz a friend had one. This volkswagen cold air intake adds HP to his engine and also improves fuel economy. Mine doesn't have yet. I'm broke right now but soon I'll try that. I heard it's the cheapest to increase HP. Good luck! hope a fond a good one...

Hummer Driver,
 I think you've got the right idea! I just installed my True Flow yesterday. It's a nice system,but very simple. I still can't figure out what a "resonator box" is suppose to do. I think your idea of using your 06' K&N would work if you can get past 2 points. 1) Will the K&N couplers match the size of the throttle body and more importantly the air box? 2) Is the K&N tube bend at the right angle to line them both up? If so, fire up that hack saw and get goin' ! As I stated in a previous post, with the True Flow or any system that retains the stock air box, you can use any filter you want-True Flow foam, stock, K&N, Fram Air Hog. The True Flow filter comes with the arrow shaped retainer that holds it in the air box(like the stock filter) and a hose clamp.(that the stock filter does not have- go figure). The K&N for the 07' is a barrel shaped(not coned) but should work just fine. So lets' see your pipefitting(my occupation) prowess and maybe you can make other 07'/K&N owners happy.

Obie1, I have to tell you brother, I am considering doing just that. The K&N tube looks like it's bent right and of the right diameter to couple to the stock airbox, clamp that sucker on in front of the Mass Air Sensor just like the TrueFlow system does. It gets rid of the resonator box and that accordian shaped intake tube.. and I still get the emissions return in the stock box.

One thing I did measure was the throat of the K&N cone filter and it won't fit on the stock box. I would have to buy the K&N replacement barrel type filter.

The only thing I'm worried about is the alignment of the tube to the stock filter box. Laying it over the stock one it looks right, bends go the right way, etc. However the tube really needs to be inline just right with the stock box inlet sleeve in front of the air sensor. If it's off a few degrees one way or the other I don't know if that will work, the couplers K&N sends with the kit aren't very wide so I don't have a lot of wiggle room.

If I get time this weekend I may take the resonator off again and look at how the K&N tube aligns but I have to do that without cutting it so at best it would be a guesstimate.

I have a problem with the Airaid system for $200.00, all you get is a filter and some funky airdam that replace the top half of the stock selaed brether box. At least with the K&N and the True Flow you get the whole pipe. The Airaid still uses the stock resonator and accordian tube and the lower half of the breather box. Not much for two bills.... heck seems to me you could just put a filter on like a $40 K&N and it would be about the same effect as the Airaid system.

As I stated before, I think the stock H3 intake is a cold air intake. the problem areas in my mind are the paper filter and the accordian tubing and the resonator box. The Airaid only appears to address the filter issue. I can do the same thing with a $40.00 K&N OEM replacement filter...

I think the added HP and torque comes from the intake tube and removing the resonator and stock tube and of course getting the high flow filters.

Hummer Driver,
I think your assessment is right on.Unless you plan on selling your K&N or buying a 06' H3,I say go for it, what have you got to lose. If not you'll have to pop for $200 for a True Flow. If K&N were reading any of these posts,they'd realize we've done their engineering for them. Take their 06' FIPK shorten the tube so it fits between the air box and the throttle body, redesign a cone filter to fit inside the air box and Presto! Part # xxxxx for the 2007 Hummer H3. Where did I put my engineering degree, I know I left it around here somewhere?
All this, just to suck in a little more air. I'm sure you'll figure it out. Then you can suck just as much as the rest of us with peformance intakes.LOL
 
P.S. K&N may not be able to do this due to patent rights.

Guys, I took my resonator box off again last night in the garage, couldn't sleep.....

I was looking at using the 06 K&N tube and modifying it to go into the stock breather box like the True FLow system does.

I didn't pull the breather box, just the resonator and the accordian tubing between the resonator and breather. I looks like the bend on the K&N is just about right, the couplers that K&N sends with the kit is the right size IF I cut the K&N tube short on the breather side.

I'm just scared to death to try it, I can't say 100% that I can get it aligned with the throttle body and the stock breather box but it looks damn close.

I've done some reading on cold air intakes and the consensus is that the resonators are basically a muffler for the intake system. That is all it does, it has baffles in it to quiet down the air sucking into the throttle body just like a muffler does on an exhaust.

That's the main reason the cold air intakes are louder, the ones that replace the resonator and have an air dam that replaces the closed breather box should be the loudest. If you use one like the True Flow system, it uses the closed stock breather and should be quieter than a K&N. The logic is the intake sound at the filter is muffled by the sealed breather box.

One thing that bothers me about the Air Raid system that sells for $200.00 is the fact that it doesn't include a smooth bore tube between the breather and the throttle body, it uses the stock accordian system which I think degrades airflow and still uses the stock resonator box.
Secondly, the Air Raid system uses the bottom of the stock breather box and then uses an air dam to seal against the hood. So for 200 bucks you get a small air dam that replaces the top half of the stock breather (Why? I don't see any benefit to this)... and you get a $40 filter. Am I missing something here??? As far as the Air Raid system, it seems to me that you can get the same performance from their $200 kit as you can simply by changing the stock filter with an Air Raid or K&N OEM replacement. I believe the stock system is a true cold air intake system and it's sealed top and bottom to prevent engine compartment heat from entering the engine. I don't see where the dam improves this one bit on the Air Raid.

I understand the air dam on the K&N intake system. You replace then entire stock breather box so the air dam makes sense, but it simply doesn't make sense on the Air Raid design, seems like fluff to me, I need meat and taters...

I'd love to hear someone's opinion on this, I'm no car mechanic. I'm a software guru, but I did stay at a Holiday Inn Express last week.

I'm not a big fan of Airaid stuff...But I do like their Throttlebody Spacer in the cool red color.

Hummer Cold Air Intake  and K&N cold air intakes are some of the best in the business. this intakes provide the best-flowing filters and lowest-restriction airbox plumbing available today.

I'm getting too paranoid in my old age. 1 post and a link to www.coldairintakedirect.com leads me to suspect that you work for the site?

Good catch there Wu...I would have to agree with you..looks like he is trying to drum a little business.

I noticed when he joined yesterday...Interesting he just don't introduce him/herself and be done with this sly back door crap.

Maybe he'll come around and fess up.  If he does work for them, he should just contact site admins about being a sponsor, or at least represent himself as such.

His profile says he's located in LA...I'm assuming that's Lower Alabama.

To pull this back on subject... I have my 06 K&N sitting in the garage... someone from the forums was looking to buy it, but if they don't i'll cut that beast up and let you know how it turns out lol...Because I would like to use it on the 07 as well.... But I can't think of how the MAF sensor goes into the stock system for the life of me now... Now if I didn't break my digital camera... I would take pictures too lol... I think tonight I'll take a picture with my camera phone and show you how bad I broke my other cam lol..

By the time K&N does thier r&d on their intake for a vehicle that getting close to a year in production, everyone who owns a 07' H3 will have bought another brand or cut up a radiator hose from a 1962 Kenworth to make their own CIA. LOL

Dude, I have the same thing except I bought mine K&N under the assumption it would work on the 07, WRONG... I'm damn tempted to get my hack saaw and cut that damn tube and fit it to my stock breatherbox and stick a K&N filter inside. Get's rid of the resonator box and that stupid accordian center section...

I was super busy this weekend, didn't get to experiment much but it looks like it just may work with the supplied couplers with the K&N CAI system. I needed to take the breather box off and take some measurements on the system before attempting to cut the plastic K&N tube. It's hard to eyeball the alignment but it looks really close to fitting, I just fear after I cut it and try to mate it up with the breather and throttle body it'll be off a half inch or more and I'll be hosed.

Performace Curve hasn't bothered to reply to my two emails asking if I could return it. I talked to K&N and they told me if they don't let me return it to call them and they would try to help. I don't see anything soon for the 3.7L from K&N.

I'd like to sell mine and recoup as much as I can, it's unused but opened. Works only on the 2006 H3. If no one bites, I may have to get the hacksaw out and do some experimenting.

Update:

I was piddling in the garage this evening (late this evening) and decided that I had good luck with the PCMforless Loaner install I just completed that now would be a good time to get out the K&N 63-1095 Cold Air Intake system I had purchased for my 07 that would only fit the 06 model H3. I was close to selling it for a loss this wekend and decided to give it a try.

I got to looking at the True Flow system install and noticed how they were only adding a smooth intake tube between the stock breather box and the throttle body. I really couldn't tell for sure the K&N tube would fit if I cut about 6 inches of it off on the breather side. The bends and angles looked about right although there was no way to check for sure until I cut the tube and test fit it to my engine.

To make a long story short, I took off the stock resonator box and accordian tube between the throttle body and the stock breather box. I cut my K&N intake tube and it took about 4 cuts on the band saw to get it just right. I used the stock silicone straight couplers the K&N came with. I was worried they might not work if the final angles were off more than a degree or two.

I think I'm going to order a 3.5" ID silicone hump coupler for the breather side connection. The system is pretty rigid and that's probably not a good thing. I suppose the stock accordian intake tube absorbs vibration and torque movement from the engine and the fixed breather box. I noticed True Flow uses the hump couplers too and my guess is they do it to allow the tubing to flex some at the humps on either end.

Below are two pics of the K&N intake tube retrofitted to my 07 H3. Basically I've got the same thing as the True Flow system now with the exception of their foam filter. I have a K&N OEM replacewment filter inside my stock breather box. So I now have K&N filtration plus the smooth bore tubing of the K&N intake tube without the resonator box and that darn accordian intake tube.

Sweet job.  It looks great and saved you a bucket of $.  Let us know how the PCM works with the HummerDriver CAI.
