i just ordered the z-tube with stillen intake and was wondering if anyone has had problems with the set up?... or maybe tips of things that i need to be careful of while installing it.

 

I got the same setup just follow the instructions and you will be fine.
just be wary of the AC lines when installing the parts that is all.
Disconnect the Neg terminal on the battery.

Enjoy afterwards

 

Make sure you plug in the MAF sensor before you fire it up or you might throw a CEL. Also, installing the lower bolt for the HFA is a PITA. Be patient.

 

Is there a noticeable sound difference with the stillen z tube and the stillen CAI? I aleady have the stillen CAI and it sounds great. I just want to know if the stillen z tube makes it louder. Thanks.

 

Hmmm I also have the HKS exhaust sothat in itself is pretty loud at WOT.
The Z-tube def changed the note of the exhaust and I feel like the air that is coming into the throttle body is more linear compared to the G-tube. I also have a Whislte effect after lets 3700RPM and its more pronounbce in my car since i also have the TS hoods and the CAI is right by the vent.

 

Thanks for the input. I have that whistle to from the CAI at about 3700RPM as well. It sounds sick. I have the stillen TD exhaust, but it is no where near as mean sounding as the HKS.

 

i accidentally did this...does it hurt the car/engine?

 

I don't think it does any harm to the engine. I'm just not sure if the CEL goes away or has to be reset by the dealer.

 

thanks for the advise guys!!!

 

Is it just me or does the whistling sound kind of annoying like a squeaking break or something...when i first installe the stillen CAI everything sounded great and then that whistling noise came in ...is it normal?

 

Many members have mention this whistling noise with the Stillen HFAB . . . I don't hear it.

 

O ok i thought maybe mine was defective but understanding this is common..i dunno i find it a little annoying...Pay close attention to your intake and turn music off. U will probably hear it

 

Here are a few notes from my install....

 

I have the Stillen Intake and Stillen Z-tube and I love the combo. I have the whistle too, but I actually like it. Sounds kinda cool to me. All in all I am happy with my setup. My next step is to get a spacer.
