I'm not sure if it's providing better power than the stock airbox, though. It also cuts the the sound of the waste gate dumping down to very quiet, although it doesn't quiet the intake air all that much. One other bonus has been that the idle has less lope now and is overal more stable and less prone to stalling - again it's closer to the stock airbox.
After another close look at the way the stock rubber tube was designed comaperd to the HKS aluminum tube, in addition to the issues with that big blade (turbulence and reduced flow) I also looked at the way dumped air (wastegate) and vaccum for the boost controler were being recyled into back into the intake stream - in both cases the OEM tube looks to have a better design. I also think that sudden change in intake size right at the turbo inlet might be a source of problems.

It does look like using the cone and mounting plate while keeping the OEM rubber pipe worked well in my car. Even with the boost hitting late (bad boost controller) the car put down better power in that configuration than it did with the complete K&N set-up or the OEM air box.
Your mileage may vary, but it might be a way to salvage something from the purchase.

A better man - such as yourself - would not inflict the problem on someone else - - hopefully K & N will pay some attention to this condition
Ive always thought of taking mine out, but honestly no problems to date and going for over a yr now....I hate to spend more money on an intake just to see whats up..maybe I will try the stocker and a drop in...
I test drove an evo for the first time last night and was somewhat disappointed with its performance compared to the STi I test drove, but somehow I remembered being blown away the first time I rode in one. I noticed it stumbling and lurching etc. and the recirc. valve fluttered like an aftermarket or vented to atmos. one, and I finally realized it has a K&N intake on it! At certain rpms if I'd shift or be at part throttle, it really ran like ****. Possibly worse than what some of you have described 9maybe because I'm at about 7500' elevation), but only at shifts and part throttle, it ran perfect the rest of the time, albeit a bit slower than expected. Needless to say, now I know the intake is to blame as I had suspected.
My question is: some of you have said it caused your car to run very rich or lean and even detonating. This car has 26k miles and it's safe to assume it's been run hard for all of them, probably with this intake. Do you think I should worry about the life of this engine due to the amount of A/F changes caused by this intake? It's one of the only ones near me for sale, and I am somewhat inclined to buy it.

I later discovered the culprit for the cars horrible performance was due to the fact that the dork had the recirc. valve on backwards. I bought the car, turned it around, and it works fine now. Still a bit skeptical of the intake though. I took the CF "heat shield" off. I will be changing to another intake when I don't have more important things to spend $ on...
I have recently installed the K&N intake system and have run into nothing but problems. My boost still gets up to around 20-21 psi, but then under hard acceleration, the car seems as though it begins to miss fire/cut out. I am going to re-install the stock intake tube and see if this is the problem.
K&N Typhoon ... I was about to order .. good that i searched.
So you guys dont recommend the K&N typhoon? is there an alternative way.. there is a guy over here with a AEM filter, Looked good and he says its running real good with no issues.
God i miss my 350z.. you just thro anything in that Z and it will gain power, No need for a flash... next thing I will soon hear is a flash whenever i refuel the car. whats up with all the ecu reflash... is it that sensitive .. or is it that dumb
