I'm putting the stock air filter system back on.....

[kchummer]

all I gotta say is WOW....I thank anyone who posted anything negative about the K&N filter systems to get me to try the stock setup....I WILL NEVER OWN ANOTHER K&N setup in my lifetime!! My H2 is like a whole new ride....no JOKE!! I cannot believe the power the K&N took away from my ride.....Thanks IRA51 for your post about 3 months ago...I read it and decided that if u (a reputable poster), think the stock is better, than I wanted to see for myself.....and damn!! Either the ole K&N goes on Ebay or turns into a boat anchor, but will NEVER be back under the hood of my Hummer!! thanks again!! ok I'm done ranting now....lol

I have seen first hand that the "oiled" filters can have way too much on them and fawk up the maf sensors.

I had the volant kit on my last H2. The first thing I did was to clean it and get the excess oil out and through it back in. ...dealer suggested that.

The K&N's aren;t all that bad, but again the oil on those things get plugged up and can be problematic to your MAF sensor and cuse bogging once they get compltely full of crap.

fwiw. I plan to run (if I ever sell this damn Alpha and get antoher SUT) the stock setup with Airdoc's kit. It retains the stock airbox and gets rid of the noise dampner.

The biggest thing I've noticed is really how much HOT air the K&N lets in..it is NOT sealed well to be an open filter....the engine heat KILLS the motor...I noticed that the most of all....On a 95 degree day the Hummer became a dog!! that's when I realized it had to be too much hot air getting through the lousy K&N blockoff design.....NM

I know they are suposed to last longer ,but you should see the dirt on them after just one romp through the Sonoran desert. now I will admit I run it long and hard so I should expect it .I vacume them with my shop vac and after about 6 or 7 vacumes it's time for a new filter. I'm thinking of trying the Fram power core # CA9900 at rock auto for $41.00 .and with the $6.00 rebate $35.00 is not too bad

Volant is the only true cold air kit. The OEM setup is not that bad if you use a better flowing filter and and airaid intake tube.

I have an Airaid intake tube brand new in the box, if anyone wants one

As far as intake goes STOCK is wats up
