    :smileydan:Ok, last Saturday, I "cheese boxed" my intake following instructions that Nick PM'd me.

    I'm happy to report first, no engine light. Second, the mileage has increase almost 50-70 miles to the tank believe it or not. I'm floored that it made that much of a difference.

    I just wanted to say thanks Nick and thanks to the person that wrote that up. I don't have the link as it's back over "there" and I have no reason to return to it.

    Matt, I am curious if that would make a better improvement than a CAI which I have (BullyDog RFI) the older design. I know the factory intake is good up to 500hp and also filters tenfolds better than any aftermarket design. Could you PM the design as well? thanks -Justin ps thanks for the site.. me likey...me wanna helpy...

    kennedy has a pic on his site that shows how to cheese box it, lets more air flow to the filter faster....or it should

    FWIW...I've asked a couple CAi makers to show flow, and hp improvments if any..never heard 1 word from them...I won't name the makers, but all have heard of them.

    Also, there was a test done re: cai's and the Duramax stock airintake with the ac delco filter..guess which one won..:biggrin5:

    The link and instructions that were given me by Nick (Unit453)

    http://www.kennedydiesel.com/
    - Click on tech tips
    - Click on duramax tips
    - Click on dmax air intake mods


    Tires I have on it are 17" Hummer rims. 265/70/17

    Told Nick it was a rough idea - will know better on this tank though and keep you updated. I'm honestly shocked, I REALLY didn't believe it would make much of a difference at all. Overall, unless I miscalculated, it's an average of about 1.5 miles per gallon. Needless to say, I'm ecstatic! :hurray:

    Anything for better MPG's

    Question, will this mode work on a 2006 model? Seems that everything was talking 01-05 even the filter replacement. Or did I read this wrong? :errr:

    Matt, I was just wondering what year your truck is? I might have missed it so be gentle if i did. I was thinking that the best thing for an LBZ was to simply remove the airbox baffle ( the little plastic thing that looks like a fan blade) via the PPE airbox mod. Also this might be a little off topic but where is the best place to buy a replacement donaldson filter? I remember reading a while back about a new filter that was developed in part by Amsoil that was suppsoed to be a good alternative to the stock filter.

    Where is the instructions on how to do this for an 04.5 LLY? Does it make much of an improvement on the 04.5-05 or is this mostly for the 06+ trucks?

    Per kachurak's post above:

    http://www.kennedydiesel.com/
    - Click on tech tips
    - Click on duramax tips
    - Click on dmax air intake mods

    That will work for your LLY. If you don't want to remove that much plastic, you can use a hole saw and "swiss cheese" your airbox in the same places shown in Kennedy's pictures.

    I went with a full blown S&B intake that I am very pleased with, but needed that due to the big tune that I am running.

    What has me thinking that the OEM Filter is pretty much best, is...on the new Volant Intakes, doesn't the filter that they use look identical to the OEM Donaldson Filter?
