    Default New airfilter kit

    I visited a friend a few weeks back to see about getting a price on a case of oem air filters for my 2011 Silverado, I must have whined a little to much about not being able to find a Dryflow style replacement filter.
    My friend told me he'd hook me up and send a case of filters to the house and bill me later.
    One week later this showed up on my door step.

    A new K&N Blackhawk Dryflow air filter replacement system.
    Now all I have to do for payment is do a write up on performance, mpg gains, and install.
    Then get an after install Dyno tune completed in a few weeks.

    I think he's a nice friend, especially since he works for a Toyota dealer.
    I suspect he pulled a few strings, the kit was set-up and boxed for a 6LTR Denali and it came directly from K&N.
    After looking around Im seeing the same kit isnt available from most vendors for the 5.3 yet. And there were a few slight inconsistancies on the install that I had to work out. After I got finished I found a hand written note in the bottom of the box with a phone number to call if I had any install problems.
    So far the only issue I have is they didnt polish the K&N name block, just left it milled smooth. The next nice day I get time I'll polish it out and highlight the letters with black paint so it stands out better.

    I guess I did it "half way". I got the Airaid MIT tube and left the stock box and dropped in an Amsoil Ea Air filter. I think the tube is really the weak link in the intake system. The stock box is CAI already, just the stock filter is not the best. I wanted good flow, but I live on gravel roads and wanted excellent filtration. That is why I got the Amsoil air filter.

    But I have to admit, the OP intake he put on really looks good!
    Hey there, VA, what do ya' say? How many vets did you kill today?

    My original intentions were to retain the stock air box, change the supply tube, and add a dryflow filter, much like cowpie has done, and I may later put the stock air box back in with the K&N supply tube and a drop in dryflow filter.
    But with the price of this set-up I had to at least try it out.
    Claims are for an additional 12hp and 3mpg, I dont feel the hp but at the start of the second week I am seeing a gain in mpg, wont claim final #'s yet, I need a few more tanks of fuel to ensure this last tank isnt a fluke.
    The K&N leaves to many holes in the engine compartment to allow hot air intrusion for my taste, its winter now, Ill see the real truth in the summer heat.
