K&N air intake??

[boulderhummer]

Hey guys, just had a mechanic buddy of mine install the K&N intake kit (whole kit that replaces the entire stock unit). Couple good things about this kit. I do notice that the truck in more responsive and it sounds a little better. A magnaflow exhaust will be next. Anyone know where i can order that?
The problem I'm having is that the check engine light is on steady. According to our manual, this isn't abnormal. Been on the phone with K&N and 2 Hummer dealers. K N says that the Hummers computer needs about 150 miles so it can adapt to the new [more ] airflow. I know there is an extremely amount of techical knowlege with some of you guys on here. Has anyone put this on their truck, or does anyone have another alternative in regards to the engine light on. I"m about half way to the 150 mile mark, but for some reason i don't think that is going to turn the light off. the dealer said they could hook it up to the computer. i suppose that will just turn the light off for the time being.
thanks for any info guys,,i'll post some pics of the unit.

I just purchased my K&N yesterday. I will install mine by Friday. Thats if it shows up by
Thursday the 29th of September. I will monitor the instrument cluster for any thing unusual.
If I get anything or if I dont get anything indicating effects after installing the air filter I will surely post it.

BoulderHummer,

I assume that your friend dissconnected the negative terminal for a couple of hours during the install? Neither my (5.3) Yukon for my H2 (6.0) had the check engine light issues with the installation of a similar product (Airaid). However, the only issue I ever had was on a F-150. I made the mistake of not dissconnecting the ground and it gave me the check engine light. I called K&N and they told me to follow the above steps and it fixed the issue.

Let us know if it resolves itself.

The only thing that should have been switched over to the new intake is the MAF sensor. Maybe look there first to make sure it isn't damaged and the connector is on tight. If the breather hose is off some air is not being metered and may throw an excessive fuel trim code.

You can try having onstar read the codes to you with the description of the code. If you don't want to use onstar, there is one autoparts store that will read your codes for free - maybe Advanced???. Any OBDII scanner will read the code.

[boulderhummer]

thanks for the infor guys. let me know how you make out badger..
Chevy, what would i do if i have the code read by a computer. i made sure the sensor was on tight and my buddy did disconnet the negative. its a slight possibility that the lack of hooking up the hose from the snorkel to the fuel regulator may have thrown the sensor off. the instructions to the kit shows a 4mm hose is supposed to be connected to the vacum fitting then onto the fuel pressure regulator. Apparently our Hummers don't have a fuel pressure regulater.. so K&N is sending a plug for the opening. I did cap the vacum fitting, so i doubt this is the reason...we'll see

If the intake is drawing in unmetered air from either the crankcase breather or the fuel pressure port then the fuel system will adjust until it hits its limit - then throw a code. Is it possible that the MAF element was installed 180 degrees in reverse - I don't know if this is even physically possible?

[boulderhummer]

i'm not sure Chevy,,,your talking a little over my head with some of your suggestions. i am confident that the system is installed properly, i helped my friend and he is very meticulous about things. i guess i should just take it to the dealer and have them hook it up to the computer. what do you think?
thanks

K&N installed!!!!!!!!!!!!
Took about 45 min. I had no adverse affect with the engine nor did I get any instrument lights on the Drivers instrument cluster. All is great!
The engine looks a lil strange witout that air box and air resenator that has that logo Vortec 3500 on it. Make sure that the hole on the side facing towards you is capped off completely. This hole is for the fuel vent thats normally found on the GMC Canyon or Chevy Colorado. K&N has a plug for that hole Hummers that dont use it. (K&N Part #63-1095) Maybe thats a possibility of why you are getting indicators on your instrument cluster?

Here is a picture of my newest upgrade!

[crotch_rocket_pilot]

Where did you guys purchase this and how much was it?

[crotch_rocket_pilot]

Hmm, nevermind...just read the next thread and it answered my question.

[WhiteH3]

K&N installed the first Air Intake Kit on my H3, at their prototype/testing facility. Dyno'd the vehicle, etc. You can find the dyno charts on my posting in this H3 Tech Discussion area. Installation was about 2300 miles ago. I have not experienced any problems with check engine lights.

[boulderhummer]

cheapest i've seem em is on ebay,,239.00

my check engine light is still on over 200 miles,,guess its time for an appointment....

[kacyk]

How loud is the cabin with the K&N intake system? I had one in my Tundra and it was so loud I hated it. I did have an Airaid Junior in my Yukon and it was quiet.

Is the K&N kit for the H3 loud?

[boulderhummer]

definitely noticiably louder in the cabin when you step on the gas. its a higher pitch sound than the same the one i had on my gmc yukon. (same kit) it must be the big difference in engine size. for me, it is not obnoxious. i do notice the truck is more responsive and pulls better. all i can say to best answer your question is that its probably going to be a higher pitch sound than your Tundra, but for me i'm okay with it because i know the engine is running more efficient and i'm getting more horses that this truck desparately needs..
good luck man
