Help with cold air intake

Went to put the cold air intake on the H2 Sunday and ran into some problems. All the hardware was not there so I had to find some bolts and nuts that would work. But the main issue is securing the black tube onto the engine. I can get the clamp to stay on the rubber piece where it attaches to the engine but the second clamp that is to hold the tube on to the same rubber piece can not grip enough of the plastic tube to keep hold. On the black tube, there is a round lip where it would seem that you have to get the clamp in front of but for some reason I can not get it to hold. After a drive, the black tube is being barely hit with the fan blade.

Any suggestions from any of you that has installed this on an H2?

If i can chip in with two pennies:

I've seen and considered the things like Airraid cold air intakes and filters, and ultimately decided against them for these reasons

First, the factory intake is a closed box. The Airraid just has that rubber thing that presses against the hood, and in all probability the factory intake gets a cooler breath of air than the Airraid, as the Airraid almost certainly sucks some hot air from the engine compartment.

Second, the oil in the filters worries me as i've had problems with those and mass-air sensors in the past.


I do like the high pitched whistle you get at full throttle with the Airaid system, though.


I don't mean to be a downer, and i really don't know how to install the thing. CAn you swing over to where you bought the intake and ask them?

No I bought it off Ebay.

The sound of the air sucking in is way cool and it definitly makes the H2 quicker than stock. Along with the Corsa exhaust, its a super mean sounding rig.

Also, K&N is full of $hit when they say it can be installed in 90 minutes. i had 3 hrs on this thing yesterday and still not fitting right. I think I need to take off the tube and attach the one clamp to make sure its secure b4 securing it to the engine.

For over $300, this should be a real easy thing to put on. But of course its not :(

most everybody is full of crap about install times. for example, i had to order new parts and spend 3 hours to install some of the chrome and all.

good luck with it, man

My K&N went on real easy and without a hassle in about and hour and a half..taking my time and I even modified the black heat shield to fit snugger to the fender panel and front end area..the biggest headache was getting on that black weather stripping..But a ll in all a piece of cake...Blade, oiling is an issue if you over oil the filter after cleaning..But cleaning should not be necessary for at least 10,000 miles...But the brand new factory oiled on is nothing to concern yourself with in regards to the MAF...I noticed your paranoia about this in another post too..so don't worry.

did you ger the polished or plastic? I have pics of the polished one under this catagory under magnaflow install.

I bought the plastic one mainly because K&N's site said it gave more HP. Does it really? No clue and I am sure the average person could not tell.

I did remove the tube last night, placed the clamp where it needed to go to prevent it from slippng off and reinstalled. this was backwards from what the manufacture said but it worked like a charm and only took one try.

I can definitly feel it push me back in the seat which was missing with just the exhaust mod.

And when your wife says to knowck it off, then you know you have gotten the desired effect :)

Well worth the $315 shipped.

Can you tell a big difference in the exhaust tone and the intake noise?

With the Corsa exhaust rumble, I hear nothing from under the hood unless I sit there and try to hear it. If I open the hood and have someone use the gas pedal, I can hear it sucking air as it should. I dont really notice any exhaust tone difference but I can definitly tell it has more pep than before. I am still not at the Escalade speed but I am a whole lot closer. Outside of reprograming the computer or doing major engine mods, this is about as quick as the H2 will get. So I am content where it is as I dont want to do major stuff to the engine or alter the computer.

It is really cool and worth the money in my humble opinion.

I agree BT, I'm not planning SuperCharger and all, I'm quite Pleased with my Volant CAI and Magnaflow exhaust. Very noticeable difference!!

I can't speak for the H2 in this matter but on the (Avalanche) 5.7L Chevy engine with both the Corsa and K&N FIPK installed I can ...
I know GM at the time would void the warranty due to the oil in the filter or if you over lubed it after cleaning it. I actually ended up removing my K&N and just cutting a hole in the stock air box to increase the airflow. It worked in my opinion just as well as the FIPK and there was no noticeable change in exhaust tone.

I've looked at the H2 K&N kits and though I'm tempted I think I'm just going to save myself the money cut a hole in the stocker instead. This assuming the stock box has the usual tiny a$$ holes as everything else I've seen.

I talked to my Hummer dealer and they say the intake wont void the warranty.

I have to say you can hear the set up sucking in air, but in my humble opinion, thats the coolness factor kicking in. Who would not want to hear their engine gaining more power while driving? Thats just soooo cool to me and even if I did not get a HP increase, its still way cool to hear it.

Yep, but I thought that was about it too. Sounded real good with the hood up and listening to it but did very little for exhaust note. As far as HP goes .. yep, I thought it added a little and definitely looked good (I had the chrome version) doing it. Personally I'm rather sick of "gaining a little" horse power wise. I drove a RAM SRT-10 (8.1L V10 Viper engine) for about 2 years as a (summer) daily driver and every time that thing took a breath it was 3 bucks worth of gas LOL! In comparison my H2 is an economy vehicle hehehe. It was fun though, I'll admit that!
I guess here in my umm .. older days I'm just as happy with the stock performance of the H2 as I was blasting down a straight piece of road at 120+ with a Porsche trying to keep up hehehehe ....
